所以就寫了這段程式供以後使用
public static void CreateExcel(DataTable dt, string fileName)
{
StringBuilder sb = new StringBuilder();
// Print Header
for (int i = 0; i < dt.Columns.Count; i++)
{
sb.Append(dt.Columns[i].ColumnName);
sb.Append("\t");
}
sb.Append("\n");
// Print Content
for (int i = 0; i < dt.Rows.Count; i++)
{
for (int j = 0; j < dt.Columns.Count; j++)
{
sb.Append(dt.Rows[i][j]);
sb.Append("\t");
}
sb.Append("\n");
}
string temp = string.Format("attachment;filename={0}", fileName);
HttpContext.Current.Response.ClearHeaders();
HttpContext.Current.Response.Charset = "UTF-8";
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.Default;
HttpContext.Current.Response.AppendHeader("Content-disposition", temp);
HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
HttpContext.Current.Response.Write(sb.ToString());
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();
}
