1.添加引用：
Aspose.Cells.dll（我们就叫工具包吧，可以从网上下载。关于它的操作我在“Aspose.Cells操作说明 中文版 下载 Aspose C# 导出Excel 实例”一文中的说。这里你暂时也可不理会它。）
即使没有安装office也能用噢，这是一个好强的大工具。
2.编写Excel操作类
using System;
using System.Collections.Generic;
using System.Text;
using Aspose.Cells;
using System.Data;
public class AsposeExcel
{
private string outFileName = "";
private string fullFilename = "";
private Workbook book = null;
private Worksheet sheet = null;
public AsposeExcel(string outfilename, string tempfilename) //导出构造数
{
outFileName = outfilename;
book = new Workbook();
// book.Open(tempfilename);这里我们暂时不用模板
sheet = book.Worksheets[0];
}
public AsposeExcel(string fullfilename) //导入构造数
{
fullFilename = fullfilename;
// book = new Workbook();
// book.Open(tempfilename);
// sheet = book.Worksheets[0];
}
private void AddTitle(string title, int columnCount)
{
sheet.Cells.Merge(0, 0, 1, columnCount);
sheet.Cells.Merge(1, 0, 1, columnCount);
Cell cell1 = sheet.Cells[0, 0];
cell1.PutValue(title);
cell1.Style.HorizontalAlignment = TextAlignmentType.Center;
cell1.Style.Font.Name = "黑体";
cell1.Style.Font.Size = 14;
cell1.Style.Font.IsBold = true;
Cell cell2 = sheet.Cells[1, 0];
cell1.PutValue("查询时间：" + DateTime.Now.ToLocalTime());
cell2.SetStyle(cell1.Style);
}
private void AddHeader(DataTable dt)
{
Cell cell = null;
for (int col = 0; col < dt.Columns.Count; col++)
{
cell = sheet.Cells[0, col];
cell.PutValue(dt.Columns[col].ColumnName);
cell.Style.Font.IsBold = true;
}
}
private void AddBody(DataTable dt)
{
for (int r = 0; r < dt.Rows.Count; r++)
{
for (int c = 0; c < dt.Columns.Count; c++)
{
sheet.Cells[r + 1, c].PutValue(dt.Rows[R][c].ToString());
}
}
}
//导出------------下一篇会用到这个方法
public Boolean DatatableToExcel(DataTable dt)
{
Boolean yn = false;
try
{
//sheet.Name = sheetName;
//AddTitle(title, dt.Columns.Count);
//AddHeader(dt);
AddBody(dt);
sheet.AutoFitColumns();
//sheet.AutoFitRows();
book.Save(outFileName);
yn = true;
return yn;
}
catch (Exception e)
{
return yn;
// throw e;
}
}
public DataTable ExcelToDatatalbe()//导入
{
Workbook book = new Workbook();
book.Open(fullFilename);
Worksheet sheet = book.Worksheets[0];
Cells cells = sheet.Cells;
//获取excel中的数据保存到一个datatable中
DataTable dt_Import = cells.ExportDataTableAsString(0, 0, cells.MaxDataRow + 1, cells.MaxDataColumn + 1, false);
// dt_Import.
return dt_Import;
}
}[/R]
3. Word导出
//设置文件类型
// saveFileDialog为一个对话框控件
//如果没有人工具栏中拉，
//可以：SaveFileDialog saveFileDialog1=new SaveFileDialog();
saveFileDialog1.Filter = "导出Excel (*.xls)|*.xls|Word (*.doc)|*.doc";
saveFileDialog1.FilterIndex = 1;
saveFileDialog1.RestoreDirectory = true;
saveFileDialog1.CreatePrompt = true;
saveFileDialog1.Title = "导出文件保存路径";
//saveFileDialog1.ShowDialog();
//string strName = saveFileDialog1.FileName;
//设置默认文件类型显示顺序
//saveFileDialog1.FilterIndex = 2;
//保存对话框是否记忆上次打开的目录
saveFileDialog1.RestoreDirectory = true;
//点了保存按钮进入
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
//获得文件路径
string localFilePath = saveFileDialog1.FileName.ToString();
//获取文件名，不带路径
string fileNameExt = localFilePath.Substring(localFilePath.LastIndexOf("\\") + 1);
//获取文件路径，不带文件名
string FilePath = localFilePath.Substring(0, localFilePath.LastIndexOf("\\"));
//给文件名前加上时间
string newFileName = DateTime.Now.ToString("yyyyMMdd") + fileNameExt;
//在文件名里加字符
//saveFileDialog1.FileName.Insert(1,"dameng");
saveFileDialog1.FileName = FilePath + "\\" + newFileName;
System.IO.FileStream fs = (System.IO.FileStream)saveFileDialog1.OpenFile();//输出文件
StreamWriter writer = new StreamWriter(fs);
writer.Write("tttt");//这里就是你要导出到word的内容，内容是你什么你自已DIY
writer.Flush();
writer.Close();
fs.Close();
}
4. 导出datatable到excel
DataTable dt = null;
if (ds_all.Tables[0] != null)
{
dt = ds_all.Tables[0];
}
else {
MessageBox.Show("没有数据记录", "*^_^* 温馨提示信息", MessageBoxButtons.OK);
return;
}
//上面只是取datatable，你自己diy
AsposeExcel tt = new AsposeExcel(saveFileDialog1.FileName, "");//不用模板, saveFileDialog1是什么？上面已经说过
bool OK_NO = tt.DatatableToExcel(dt);
if (OK_NO)
{
MessageBox.Show("导出成功", "*^_^* 温馨提示信息", MessageBoxButtons.OK);
}
else
{
}
5. Excel导入
private void 导入ToolStripMenuItem_Click(object sender, EventArgs e)
{
string localFilePath = "";
//点了保存按钮进入
if (openFileDialog1.ShowDialog() == DialogResult.OK)// openFileDialog1不要再问我这是什么！
{
//获得文件路径
localFilePath = openFileDialog1.FileName.ToString();
}
AsposeExcel tt = new AsposeExcel(localFilePath);
DataTable dt;
try
{
dt = tt.ExcelToDatatalbe();
}
catch (Exception ex)
{
return;
}
//有了datatable你自己就可以DIY啦,下面是我自己的你不用理
if (ddlResidence.SelectedValue == "违章确认")
{
if (dt.Rows[0][9].ToString() != "违章确认")
{
return;
}
row = dt.Rows.Count;
if (row <= 0) return;
for (int i = 0; i < dt.Rows.Count; i++)
{
bllviola.Up_Confirmed_ByVnum(dt.Rows[i][6].ToString(), dt.Rows[i][9].ToString());
}
this.GridView1.DataSource = dt;
GridView1.DataBind();
}
