C#操作word文档（三）
1. C#调用word打印信封
public static bool PrintEnvelope(string from, string to)
{
//
//string temp = Properties.Resources.EnvelopeTemplate.Replace("«ReturnAddress»", from).Replace("«ReceiverAddress»", to);
string temp = Properties.Resources.EnvelopeTemplate;
string TempPath = System.Windows.Forms.Application.ExecutablePath.ToString().Trim().Substring(0, System.Windows.Forms.Application.ExecutablePath.ToString().Trim().LastIndexOf(@"//") + 1) + "Envelope.xml";
if (File.Exists(TempPath)) File.Delete(TempPath);
System.IO.FileStream fs = new System.IO.FileStream(TempPath, System.IO.FileMode.CreateNew);
System.IO.StreamWriter sw = new System.IO.StreamWriter(fs,Encoding.UTF8);
sw.Write(temp);
sw.Close();
object fileName = TempPath;
object readOnly = false;
object isVisible = true;
object missing = System.Reflection.Missing.Value;
object range = Microsoft.Office.Interop.Word.WdPrintOutRange.wdPrintCurrentPage;
Microsoft.Office.Interop.Word.Application wordApp;
//Document d = new DocumentClass();
try
...{
object o = Marshal.GetActiveObject("Word.Application");
wordApp = o as Microsoft.Office.Interop.Word.Application;
}
catch
...{
wordApp = new ApplicationClass();
}
Document d = wordApp.Documents.Open(ref fileName, ref missing, ref missing,
ref missing, ref missing, ref missing, ref missing, ref missing, ref missing,
ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);
//replace
d.Envelope.ReturnAddress.Text = from;
d.Envelope.Address.Text = to;
//object findText="«ReturnAddress»";
//object replaceWidth=from;
//wordApp.Selection.Find.Execute(ref findText, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref replaceWidth, ref missing, ref missing, ref missing, ref missing, ref missing);
//object findText2 = "«ReceiverAddress»";
//object replaceWidth2 = to;
//wordApp.Selection.Find.Execute(ref findText2, ref missing, ref missing, ref missing, ref missing, ref missing, ref readOnly, ref missing, ref missing, ref replaceWidth2, ref missing, ref missing, ref missing, ref missing, ref missing);
//
d.Activate();
d.PrintOut(ref missing, ref missing, ref range, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);
d.Close(ref readOnly, ref missing, ref missing);
File.Delete(TempPath);
return true;
}
2.C#实现Word中表格信息读取
很多时候，会有很多信息存放在Word文档中。而我们需要把这些信息提取出来，另做它用。而Word的格式是ms的机密，不知道有没有NB人可以对其做字符流的分析，反正我是没这能力也没这打算。所以就只能用ms提供的组件来进行编程。但ms没有提供托管的类库，而是提供了对com组件的PIA转换。具体添加，使用和相关知识，可以参见kaneboy's blog中的http://blog.joycode.com/kaneboy/articles/67688.aspx。高手的讲解，很是清晰。
而我想做的是对word文档中的表信息进行提取。网上很难找到相关的代码（打开一个已有文档，对其内容进行分析），但我觉得这种工作是很有意义的。写了一段小的Demo，如下：
object oFileName = @"C:/Documents and Settings/liush/My Documents/TestDoc.doc";
object oReadOnly = true;
object oMissing = System.Reflection.Missing.Value;
Word._Application oWord;
Word._Document oDoc;
oWord = new Word.Application();
oWord.Visible = true;//只是为了方便观察
oDoc = oWord.Documents.Open(ref oFileName, ref oMissing, ref oReadOnly, ref oMissing, ref oMissing,
ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing);
//MessageBox.Show(oDoc.Tables.Count.ToString());
for (int tablePos = 1; tablePos <= oDoc.Tables.Count; tablePos++)
{
Word.Table nowTable = oDoc.Tables[tablePos];
string tableMessage = string.Format("第{0}/{1}个表:/n", tablePos, oDoc.Tables.Count);
for (int rowPos = 1; rowPos <= nowTable.Rows.Count; rowPos++)
{
for (int columPos = 1; columPos <= nowTable.Columns.Count; columPos++)
{
tableMessage += nowTable.Cell(rowPos, columPos).Range.Text;
tableMessage = tableMessage.Remove(tableMessage.Length - 2, 2);//remove /r/a
tableMessage += "/t";
}
tableMessage += "/n";
}
MessageBox.Show(tableMessage);
}
如果看过了上面kaneboy的文章（这是一个系列的之一），再看这段代码应该不会很难理解。打开一个已有文档，然后遍历其中的所有的表。这里只是简单的将信息显示出来，具体实践上可以对这些信息进行分析。做完这些后，终于找到了一些官方的支持文档，地址如下：
http://msdn2.microsoft.com/zh-CN/library/y1xatbkd.aspx
其中的word任务有对word各种操作的简单代码事例，用vb和c#写的。看完之后，我想每个人都会明白vb对com的支持比c#不是简单明了一点两点。（可以看下这个http://blog.joycode.com/kaneboy/archive/2005/08/03/61489.aspx）同样的代码，用vb实现打开word文档的操作，代码如下：
Dim fileName As String = "C:/Documents and Settings/liush/My Documents/TestDoc.doc"
Dim isReadOnly As Boolean = True
Dim wordApplication As Word.Application = New Word.Application()
Dim wordDocument As Word.Document
wordApplication.Visible = True
wordDocument = wordApplication.Documents.Open(fileName, , isReadOnly)
所以，下次我要做COM操作的时候，我还会回归我可爱的VB的。但是，用了太久的C#毛病越来越多了，动不动就习惯性加括号，加分号。。。
3.C#读取Word中的表格
其实，MicroSoft提供了很多类和借口供程序员们使用。最近一个项目中，需要对Word中的表格进行操作：因为老板要求将内部控管系统做成Web版的，以便更好地跟台湾沟通，但是网络很慢，所以在网页上输入一些数据就很讨厌，SO，需要制订一个规格的文文件，比如Word，填写好文档后上传到FTP上，我们再用一支程序扫描这些文文件，自动添加到数据库中。。。一开始的时候，觉得好没方向啊，到网上搜了一下，发现原来有很多前辈早在N年前就已经开始这方面的工作了。
{
try
{
object fileName = "E://BB.doc";
object readOnly = false;
object isVisible = true;
object missing = System.Reflection.Missing.Value;
// 打开要操作的 Word 文檔
Word.Document oWordDoc = oWordApp.Documents.Open(ref fileName, ref missing,ref readOnly,
ref missing, ref missing, ref missing, ref missing, ref missing, ref missing,
ref missing, ref missing, ref isVisible,ref missing,ref missing,ref missing,ref missing);
string strProjName = nowTable.Cell(2, 2).Range.Text.ToString();
string strAssignEmployeeName = nowTable.Cell(3, 2).Range.Text.ToString();
string strAssignDate = nowTable.Cell(3, 4).Range.Text.ToString();
string strPreFinishDate = nowTable.Cell(4, 2).Range.Text.ToString();
string strChargeEmployeeName = nowTable.Cell(5, 2).Range.Text.ToString();
string strDesc = nowTable.Cell(8, 2).Range.Text.ToString();
string strRem = nowTable.Cell(8, 3).Range.Text.ToString();

使用模板
如果您要使用自动化功能创建的文档都是通用格式，则利用基于预设格式的模板的新文档来开始创建过程会更加容易。与从头创建文档相比，将某个模板与 Word 自动化客户端配合使用有两大优点：
| • | 您可以对整个文档中的对象的格式设置和布局施加更多控制。 |
| • | 可以使用较少的代码创建文档。 |
object oTemplate = "c://MyTemplate.dot"; oDoc = oWord.Documents.Add(ref oTemplate, ref oMissing, ref oMissing, ref oMissing);
object oBookMark = "MyBookmark"; oDoc.Bookmarks.Item(ref oBookMark).Range.Text = "Some Text Here";
object oStyleName = "MyStyle"; oDoc.Bookmarks.Item(ref oBookMark).Range.set_Style(ref oStyleName);
object oStyleName = "MyStyle"; oWord.Selection.set_Style(ref oStyleName); 5.总结下C#将WORD转PDF
首先安装WORD和WPS(2005个人版就OK了)
操作ＷPS配置说明
using WPS;
1.运行Dcomcnfg.exe
2.组件服务――计算机――我的电脑――DCOM配置――找到WPS文档
3.点击属性
4.选择“安全性”
5.选定“使用自定义访问权限”和“使用自定义启动权限”
6.分别编辑权限，添加Everyone（ASPNET,VS Developers,Debugger User）
7.选择“身份标识”，在选定“交互式用户” 即可
9.在Web.config里加
object MissingValue=Type.Missing;
WPSApp = new WPS.ApplicationClass();
WPSApp.Visible = false;
object Unknown =Type.Missing;
String upPath;
upPath=Server.MapPath("tempup//" +Request.Cookies["code"].Value +"//");
if(!Directory.Exists(upPath))
Directory.CreateDirectory(upPath);
object wpsurl = upPath +upfile.PostedFile.FileName.Substring(upfile.PostedFile.FileName.LastIndexOf("
//"),upfile.PostedFile.FileName.Length - upfile.PostedFile.FileName.LastIndexOf("//"));
//string wpsurl=Source2.ToString();
object wpsurls=wpsurl+".pdf";
WPS.Document WPSDocument = WPSApp.Documents.Add(ref wpsurl, false, 0, true);
WPSDocument.ExportPdf(wpsurl+".pdf","","");
db.dbconn conn = new dbconn();
string sql;
sql=@"update maindata set pdf_furl='"+wpsurls+"'";
conn.doexecsql(sql);
object save = false;
WPSApp.Quit(ref save,ref Unknown,ref Unknown);
System.Runtime.InteropServices.Marshal.ReleaseComObject(WPSApp);
6.C#操作word,如何进行查找和替换？
说明：请在工程中引用“Microsoft Word 9.0 object library”的Microsoft COM组件。该组件提供的类和方法来读取Word文档。
using System;
using System.IO;
using System.Reflection;
using Word;
//----------------------------------------------------------------------
string WordContent = "";
object saveChanges = WdSaveOptions.wdDoNotSaveChanges;
Word.Application app = new ApplicationClass();
try
{
object fileName = fileDoc.Value;
object optional= Missing.Value;
object visible=true;
if(File.Exists(fileName.ToString()))
{
Word.Document doc = app.Documents.Open(
ref fileName,
ref optional,
ref optional,
ref optional,
ref optional,
ref optional,
ref optional,
ref optional,
ref optional,
ref optional,
ref optional,
ref visible);
object first = 0;
object units = WdUnits.wdCharacter;
object last=doc.Characters.Count;
Range range= doc.Range(ref first, ref last);
//替换
#region 方法一，特点是非常简单
//Word.range.Text = range.Text.Replace(txtOldValue.Text, txtNewValue.Text);
#endregion
#region 方法二，特别是可以实现复杂的查找替换
Word.Find finder = range.Find;
finder.ClearFormatting();
object missingValue = Type.Missing;
object findStr = txtOldValue.Text;
object replaceStr = txtNewValue.Text;
object replaceArea = Word.WdReplace.wdReplaceAll;
if (finder.Execute(ref findStr, ref missingValue, ref missingValue,
ref missingValue, ref missingValue, ref missingValue,
ref missingValue, ref missingValue, ref missingValue,
ref replaceStr, ref replaceArea, ref missingValue,
ref missingValue, ref missingValue, ref missingValue))
{
//Text found,and replaceed
//range.Select();
}
#endregion
WordContent = "成功替换 " + txtOldValue.Text + " at " + DateTime.Now.ToString();
saveChanges = WdSaveOptions.wdSaveChanges;
}
else
{
WordContent = "指定目录下的无该文件";
}
txtContent.Text = WordContent;
}
catch(Exception Ex)
{
txtContent.Text = Ex.Message ;
}
finally
{
//退出保存
object originalFormat = Missing.Value;
object routeDocument = Missing.Value;
app.Quit(ref saveChanges, ref originalFormat, ref routeDocument);
app = null;
}
8.ASP.NET 2.0,C#----利用GridView控件导出其他文件（导出Excel，导出Word文件）
// 注意，在Visual Studio2005平台下，如果使用GridView导出文件，
//就必须重载VerifyRenderingInServerForm方法
public override void VerifyRenderingInServerForm(Control control)
{
}
///
/// 导出到文件的方法，
///
///
private void toFiles(int Model)
{
string strFileName = DateTime.Now.ToString("yyyyMMdd-hhmmss");
System.Web.HttpContext HC = System.Web.HttpContext.Current;
HC.Response.Clear();
HC.Response.Buffer = true;
HC.Response.ContentEncoding = System.Text.Encoding.UTF8;//设置输出流为简体中文
if (Model == 1)
{
//---导出为Excel文件
HC.Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(strFileName, System.Text.Encoding.UTF8) + ".xls");
HC.Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。
}
else
{
//--- 导出为Word文件
HC.Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(strFileName, System.Text.Encoding.UTF8) + ".doc");
HC.Response.ContentType = "application/ms-word";//设置输出文件类型为Word文件。
}
System.IO.StringWriter sw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htw = new System.Web.UI.HtmlTextWriter(sw);
this.GridView1.RenderControl(htw);
HC.Response.Write(sw.ToString());
HC.Response.End();
}
//-导出为Excel文件
protected void ToExecl_Click(object sender, EventArgs e)
