將ASP.NET Gridview轉換為Excel

Question

我有一個帶有Gridview的頁面，當單擊按鈕時，我應該將數據從Gridview導出到.xls文件。 我已經嘗試了很多方法。 這是我的代碼：

protected void export_Click(object sender, EventArgs e)
    {
        Response.ClearContent();
        //Response.Buffer = true;
        //Response.ClearHeaders();
        //Response.CacheControl = "no-cache";
        //Response.AddHeader("Pragma", "no-cache");
        Response.AddHeader("Content-Disposion","attachment; filename=Clients.xls");
        Response.ContentType = "application/excel";
        StringWriter swriter = new StringWriter();
        HtmlTextWriter hwriter = new HtmlTextWriter(swriter);
        grid.RenderControl(hwriter);
        Response.Write(swriter.ToString());
        Response.End();
    }

問題是當我單擊按鈕時，它正在導出aspx文件。 我已經嘗試了Stackoverflow中的所有答案以及其他來源的答案。 但是，我無法糾正它。 我需要確切的理由以及可能的解決方案。（我也嘗試將Content-type為"application/excel" ， "application/vn" ， "application/vn-excel" 。）

您只需遵循以下代碼，即可正常工作。

 protected void cmdExport_Click(object sender, EventArgs e) { Response.Clear(); Response.AddHeader("content-disposition", "attachment; filename=SupplierList.xls"); Response.ContentType = "application/vnd.xls"; System.IO.StringWriter WriteItem = new System.IO.StringWriter(); System.Web.UI.HtmlTextWriter htmlText = new HtmlTextWriter(WriteItem); GridView1.AllowPaging = false; DataTable dtSupplier = (DataTable)ViewState["dtSupplier"]; GridView1.DataSource = dtSupplier; GridView1.DataBind(); GridView1.RenderControl(htmlText); Response.Write(WriteItem.ToString()); Response.End(); } 

希望這會幫助你。 謝謝
