C#实现对Word文件读写
手头上的一个项目报表相对比较简单,所以报表打印采用VBA引擎,通过定制Word模版,然后根据模版需要填充数据,然后OK,打印即可。
实现方法:首先需要引用VBA组建,我用的是Office2003 Professional,Dll版本号为Microsoft Word11.0
另外当然还需要引用Interop.Word.Dll.
代码如下:
///
#region 打开Word文档,并且返回对象wDoc,wDoc
///
///
打开Word文档,并且返回对象wDoc,wDoc
///
///
完整Word文件路径+名称
///
返回的Word.Document wDoc对象
///
返回的Word.Application对象
public
static
void
CreateWordDocument(
string
FileName,
ref
Word.Document wDoc,
ref
Word.Application WApp)
{
if
(FileName
==
""
)
return
;
Word.Document thisDocument
=
null
;
Word.FormFields formFields
=
null
;
Word.Application thisApplication
=
new
Word.ApplicationClass();
thisApplication.Visible
=
true
;
thisApplication.Caption
=
""
;
thisApplication.Options.CheckSpellingAsYouType
=
false
;
thisApplication.Options.CheckGrammarAsYouType
=
false
;
Object filename
=
FileName;
Object ConfirmConversions
=
false
;
Object ReadOnly
=
true
;
Object AddToRecentFiles
=
false
;
Object PasswordDocument
=
System.Type.Missing;
Object PasswordTemplate
=
System.Type.Missing;
Object Revert
=
System.Type.Missing;
Object WritePasswordDocument
=
System.Type.Missing;
Object WritePasswordTemplate
=
System.Type.Missing;
Object Format
=
System.Type.Missing;
Object Encoding
=
System.Type.Missing;
Object Visible
=
System.Type.Missing;
Object OpenAndRepair
=
System.Type.Missing;
Object DocumentDirection
=
System.Type.Missing;
Object NoEncodingDialog
=
System.Type.Missing;
Object XMLTransform
=
System.Type.Missing;
try
{
Word.Document wordDoc
=
thisApplication.Documents.Open(
ref
filename,
ref
ConfirmConversions,
ref
ReadOnly,
ref
AddToRecentFiles,
ref
PasswordDocument,
ref
PasswordTemplate,

ref

ref

thisDocument
=
wordDoc;
wDoc
=
wordDoc;
WApp
=
thisApplication;
formFields
=
wordDoc.FormFields;
}
catch
(Exception ex)
{
MessageBox.Show(ex.Message);
}
}
#endregion
调用上面静态方法,打开目标文件并且把DataGrid中数据填充到对应Word标签中去
///
#region Word填充数据(For Example)
///
///
Word填充数据
///
private
void
WordLoadData()
{
Word.Document wDoc
=
null
;
Word.Application wApp
=
null
;
sysFun.CreateWordDocument(
"
E:\\监测报告(new).dot
"
,
ref
wDoc,
ref
wApp);
//
对标签"C"进行填充
object
bkmC
=
"
C
"
;
if
(wApp.ActiveDocument.Bookmarks.Exists(
"
C
"
)
==
true
)
{
wApp.ActiveDocument.Bookmarks.get_Item
(
ref
bkmC).Select();
}
wApp.Selection.TypeText(
this
.txt1.Text);
object
bkmG
=
"
TWaterTable3
"
;
object
unit;
object
count;
//
移动数
object
extend;
extend
=
Word.WdMovementType.wdExtend;
unit
=
Word.WdUnits.wdCell;
//
把DataGrid中数据填充到标签TWaterTable3上
if
(wApp.ActiveDocument.Bookmarks.Exists(
"
TWaterTable3
"
)
==
true
)
{
wApp.ActiveDocument.Bookmarks.get_Item
(
ref
bkmG).Select();
for
(
int
i
=
0
;i {
if
(i
==
0
)
{
count
=
1
;
}
else
{
count
=
0
;
}
//
需填充5列数据
wApp.Selection.Move(
ref
unit,
ref
count);
wApp.Selection.TypeText(gridEX1.GetRow(i).Cells[
0
].Text);
count
=
1
;
wApp.Selection.Move(
ref
unit,
ref
count);
wApp.Selection.TypeText(gridEX1.GetRow(i).Cells[
1
].Text);
wApp.Selection.Move(
ref
unit,
ref
count);
wApp.Selection.TypeText(gridEX1.GetRow(i).Cells[
2
].Text);
wApp.Selection.Move(
ref
unit,
ref
count);
wApp.Selection.TypeText(gridEX1.GetRow(i).Cells[
3
].Text);
wApp.Selection.Move(
ref
unit,
ref
count);
wApp.Selection.TypeText(gridEX1.GetRow(i).Cells[
4
].Text);
//
换行
wApp.Selection.MoveRight(
ref
unit,
ref
count,
ref
extend);
}
}
}
#endregion
然后就OK了,在对标签表控制要注意列循环和换行.
