Dai ma ru xia :
private void btnExcel_Click(object sender, System.EventArgs e)
{
Response.Clear();
Response.Buffer= true;
Response.ContentType = "application/vnd.ms-excel";
Response.Charset = "";
this.EnableViewState = false;
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
this.ClearControls(DataGrid1);
DataGrid1.RenderControl(oHtmlTextWriter);
Response.Write(oStringWriter.ToString());
Response.End();
}


private void ClearControls(Control control)
{
for (int i=control.Controls.Count -1; i>=0; i--)

我只知道windows的
昨天刚学的，这种问题自己先搜索以下
1添加com组件 microsoft excel10.0 object library
2 using Excel
3 public bool TransToExcel(string storeprocedureName)
{
try
{
Excel.Application myExcel=new ApplicationClass();
object filename=System.IO.Directory.GetCurrentDirectory();
System.DateTime.Now.ToFileTime().ToString()+".xls";
object nothing=System.Reflection.Missing.Value ;
myExcel.Workbooks.Add(nothing);
SqlServer ss=new SqlServer();
DataSet ds=ss.ExcelDataSet(storeprocedureName);
for(int i=0;i<ds.Tables[0].Columns.Count;i++)
{
myExcel.Cells[1,i+1]=ds.Tables[0].Columns[i].ColumnName; }
for(int i=0;i<ds.Tables[0].Rows.Count;i++)
{
for(int j=0;j<ds.Tables[0].Columns.Count;j++)
{
myExcel.Cells[i+2,j+1]=ds.Tables[0].Rows[i][j].ToString();
}
}
myExcel.ActiveWorkbook._SaveAs(filename,nothing,nothing,nothing,nothing,nothing,XlSaveAsAccessMode.xlExclusive,nothing,nothing,nothing,nothing);
myExcel.Visible=true;
return true;
}
catch(Exception ee)
{
MessageBox.Show(ee.ToString());return false;
}
