error message after converting datatable to excel in asp.net c#
在 asp.net c#
中将数据表转换为 excel 后出现错误消息
下面是我正在使用的代码
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", "Customers.xls"));
Response.ContentType = "application/ms-excel";
DataTable dt = ds.Tables[0];
string str = string.Empty;
foreach (DataColumn dtcol in dt.Columns)
{
Response.Write(str + dtcol.ColumnName);
str = "\t";
}
Response.Write("\n");
foreach (DataRow dr in dt.Rows)
{
str = "";
for (int j = 0; j < dt.Columns.Count; j++)
{
Response.Write(str + Convert.ToString(dr[j]));
str = "\t";
}
Response.Write("\n");
}
Response.End();
错误信息是
![Your trying to open different format or corrupted file ][2]
点击确定后打开,但我不想显示此消息....
我哪里出错了...
谢谢...
您的内容类型有误。您正在创建 CSV 输出,而不是 Excel。将内容类型更改为 text/csv 并将文件扩展名更改为 .csv.
