数据导出到Excel中

自己修改后的一个数据导出到Excel的方法,粘出来与大家共享.

只需要将             System.Web.HttpContext.Current.Response.Charset =              System.Web.HttpContext.Current.Response.Buffer =              System.Web.HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding(             System.Web.HttpContext.Current.Response.AppendHeader(             System.Web.HttpContext.Current.Response.ContentType =                                        DataRow[] myRow = dt.Select();
             ;
                          ; k < dt.Columns.Count; k++)
             {
                 ))
                 {
                     colHeaders += dt.Columns[k].ToString() +                  }
                                  {
                     colHeaders += dt.Columns[k].ToString() +                  }
             }
             System.Web.HttpContext.Current.Response.Output.Write(colHeaders);
                          {
                 ; i < cl; i++)
                 {
                     ))
                     {
                         ls_item += row[i].ToString().Replace(                     }
                                          {
                         ls_item += row[i].ToString().Replace(                     }
                 }
                 System.Web.HttpContext.Current.Response.Output.Write(ls_item);
                 ls_item =              }
             System.Web.HttpContext.Current.Response.Output.Flush();
             System.Web.HttpContext.Current.Response.End();
 
         }
