DataGrid里的数据导出成xls文件

本文介绍将DataGrid里的数据导出成xls文件

代码如下：（写在导出按钮的Click事件里）

 

string conn=System.Configuration.ConfigurationSettings.AppSettings["Connection"];
try
{
SqlConnection myConn=new SqlConnection(conn);
myConn.Open();
SqlDataAdapter myDa=new SqlDataAdapter("select * from Customers",myConn);
DataSet myDs=new DataSet();
myDa.Fill(myDs,"Customers");
DataTable myDt=myDs.Tables["Customers"];
StringWriter mySw=new StringWriter();
mySw.WriteLine("CompanyName/tAddress/tCity/tCountry/tPhone");
foreach(DataRow myDr in myDt.Rows)
{
mySw.WriteLine(myDr["CompanyName"]+"/t"+myDr["Address"]+"/t"+myDr["City"]+"/t"+myDr["Country"]+"/t"+myDr["Phone"]);
}
mySw.Close();
Response.AddHeader("Content-Disposition", "attachment; filename=test.xls");
Response.ContentType = "application/ms-excel";
Response.ContentEncoding=System.Text.Encoding.GetEncoding("GB2312");
Response.Write(mySw);
Response.End();
}
catch(SqlException ex)
{
Console.WriteLine("Exception in AdminList:"+ex.Message);
}
