.net导出excel

在网上找了几个导出excel的信息，但有些不是很理想，所以把找到的比较好的记录下来。

      下面是方法：

  public void CreateExcel(DataTable dt, string FileType, string FileName)
        {
            Response.Clear();
            Response.Charset = "UTF-8";
            Response.Buffer = true;
            Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
            Response.AppendHeader("Content-Disposition", "attachment;filename=\"" + System.Web.HttpUtility.UrlEncode(FileName, System.Text.Encoding.UTF8) + ".xls\"");
            Response.ContentType = FileType;
            string colHeaders = string.Empty;
            string ls_item = string.Empty;
            DataRow[] myRow = dt.Select();
            int i = 0;
            int cl = dt.Columns.Count;
            for (int j = 0; j < dt.Columns.Count; j++)
            {
                ls_item += dt.Columns[j].ColumnName + "\t"; //栏位：自动跳到下一单元格  
            }
            ls_item = ls_item.Substring(0, ls_item.Length - 1) + "\n";
            foreach (DataRow row in myRow)
            {
                for (i = 0; i < cl; i++)
                {
                    if (i == (cl - 1))
                    {
                        ls_item += row[i].ToString() + "\n";
                    }
                    else
                    {
                        ls_item += row[i].ToString() + "\t";
                    }
                }
                Response.Output.Write(ls_item);
                ls_item = string.Empty;
            }
            Response.Output.Flush();
            Response.End();
        }

如何使用：

CreateExcel( ts.getdata(), "application/ms-excel", "Excel" + DateTime.Now.ToString("yyyy-MM-dd HHmmss") + ".xls");//调用函数
