ASP.NET导出Excel

public void ExPort(){

System.IO.StringWriter sw = new System.IO.StringWriter();

string sql="";

Datable dt=DBhelper.qery(sql);//查询出要导出内容的表

String s="";

int rowcount = 50;//导出的行数

int ColumnCount = dt.Columns.Count;//d导出表的列数

for (int i = 0; i < rowcount; i++)

{

for (int j = 0; j < ColumnCount; j++)

{

s = s + dt.Rows[i][j] + "\t";

}

}

sw.WriteLine(s.Trim());

s = "";

}

sw.Close();

Response.AddHeader("Content-Disposition", "attachment; filename=RechargeSearch.xls");

Response.ContentType = "application/ms-excel";

Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");

Response.Write(sw);

Response.End();



}

效果图如下
