winform中如何把datagrid中的数据写入excel2003中，有详细代码更好

Answer 1

参考下
private void CreateExcel(string strName,DataTable dt)
{
Excel._Application excel= new  Excel.ApplicationClass();;
int rowIndex=1;
int colIndex=0;

System.Reflection.Missing miss = System.Reflection.Missing.Value;
Excel.Workbooks  objbooks = (Excel.Workbooks)excel.Workbooks;
Excel.Workbook   objbook  = (Excel.Workbook)(objbooks.Add(miss));
Excel.Worksheet  objsheet = (Excel.Worksheet)objbook.ActiveSheet; foreach(DataColumn col in dt.Columns)
{
colIndex++; 
excel.Cells[1,colIndex]=col.ColumnName;    
} foreach(DataRow row in dt.Rows)
{
rowIndex++;
colIndex=0;
foreach(DataColumn col in dt.Columns)
{
colIndex++;
excel.Cells[rowIndex,colIndex]=row[col.ColumnName].ToString();
}
}
                            

objsheet.SaveAs (strName,miss,miss,miss,miss,miss,Excel.XlSaveAsAccessMode.xlNoChange,miss,miss);

objbook.Close(false,miss,miss);
objbooks.Close();
excel.Quit(); //System.Runtime.InteropServices.Marshal.ReleaseComObject();
System.Runtime.InteropServices.Marshal.ReleaseComObject(objsheet);
System.Runtime.InteropServices.Marshal.ReleaseComObject(objbook);
System.Runtime.InteropServices.Marshal.ReleaseComObject(objbooks);
System.Runtime.InteropServices.Marshal.ReleaseComObject(excel);
GC.Collect();
}

Answer 4

DataGrid数据导入Excel 
出处    
 
 if(DataGrid1.Items.Count==0)
    {
     Response.Write("<script>alert('对不起,你没有查询到任何记录,不能导出数据')</script>");
    }
    else
    {           Response.Clear(); 
     Response.Buffer= true;
     Response.Charset="GB2312";
     Response.AppendHeader("Content-Disposition","attachment;filename=FileName.xls");
     Response.ContentEncoding=System.Text.Encoding.GetEncoding("GB2312");
     //设置输出流为简体中文
     Response.ContentType = "application/ms-excel";
     //设置输出文件类型为excel文件。
     this.EnableViewState = false;
     System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN",true);
     System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad);
     System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
     DataGrid1.RenderControl(oHtmlTextWriter);
     Response.Write(oStringWriter.ToString());
     Response.End(); 
}
