关于导出EXCEL出现的问题

[zym7511]

在某些客户的电脑上导出EXCEL文件，导出来的不是EXCEL文件，却是.aspx格式的文件,

请问谁知道为什么???有什么解决方法，在网上也没找到同类问题

求解决方案！！！！！！

以下是导出EXCEL代码
/// <summary>
/// 动态创建Grid
/// </summary>
/// <returns></returns>
private GridView CreateGrid()
{
GridView gdvGrid = new GridView();
gdvGrid.AutoGenerateColumns = false;
BoundField bf1 = new BoundField();
bf1 .HeaderText = "采购员名称";
bf1 .DataField = "采购员名称";
gdvGrid.Columns.Add(bf1 );
return gdvGrid;
}
/// <summary>
/// 导出Excel方法
/// </summary>
/// <param name="ctl"></param>
private void ToExcel(System.Web.UI.Control ctl)
{
Response.Charset = "UTF-8";
Response.AppendHeader("Content-Disposition", "attachment;filename=Excel.xls");
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.ContentType = "application/ms-excel";

ctl.Page.EnableViewState = false;
System.IO.StringWriter tw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter hw = new HtmlTextWriter(tw);

ctl.RenderControl(hw);

Response.Write(tw.ToString());
Response.End();
}

/// <summary>
/// 绑定动态表格及调用ToExcel方法
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void btnToExcel_Click(object sender, EventArgs e)
{
GridView gdvGrid = CreateGrid();
divshow.Controls.Add(gdvGrid);
DataSet ds = new DataSet();
ds = GetListFromProc();
gdvGrid.DataSource = ds.Tables["NoticeInvoiceDetail_DS1"];
gdvGrid.DataBind();

Control table = gdvGrid.Controls[gdvGrid.Controls.Count - 1];
ToExcel(table);

divshow.Controls.Clear();
}

改成

[code=C#]
public static void gSendGridInfoToExcel(Gridview GridX)

{


//赋值对象

//如果绑定数据源是DataTable和DataSet,取得行数
if (GridX.DataSource is System.Data.DataSet || GridX.DataSource is System.Data.DataTable)
{

}

}

{

}

}
if (list.Equals(System.DBNull.Value))
{
break;
}
objarr=list.ToArray();
excelCell = xSt.get_Range(excel.Cells[i+2,1],excel.Cells[i+2,iVisable]);

}
}

//数据行
for(i=0;i<iRows;i++)

}

break;
}
objarr=list.ToArray();

excelCell.Value2 = objarr;
}

}
dtTest.Dispose();

excel.Visible=true;

}
catch (System.Exception e)
{
throw e;
}
finally
{
excelCell=null;
xBk=null;
xSt=null;
excel=null;
GC.Collect();
}

}

[code]

或者找一个方法替换一下


传入Gridview 就行了。

此方法导出不支持下载软件下载
要关闭下载软件与浏览器的关联，用系统自带的文件下载
