在网站上查看ASPX时,我在单元格中找到了一个文本很少的表格,例如:
tab.Rows[1].Cells[1].innerHtml = "Booked :"
(在很多行和单元格中,但每个单元格中有不同的文本)
现在我只想点击一个按钮,表格中的数据将被下载到Excel文件中。
表ID:标签
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
//Table tbl = new Table();
TableRow tr = new TableRow();
TableCell tcel = new TableCell();
tcel.Text = "id";
tr.Cells.Add(tcel);
TableCell tcel1 = new TableCell();
tcel1.Text = "id1";
tr.Cells.Add(tcel1);
tab.Rows.Add(tr);
}
}
protected void Button1_Click(object sender, EventArgs e)
{
string filename = "ExportExcel.xls";
System.IO.StringWriter tw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
//DataGrid dgGrid = new DataGrid();
//dgGrid.DataSource = tbl;
//dgGrid.DataBind();
//Get the HTML for the control.
tab.RenderControl(hw);
//Write the HTML back to the browser.
//Response.ContentType = application/vnd.ms-excel;
Response.ContentType = "application/vnd.ms-excel";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + "");
this.EnableViewState = false;
Response.Write(tw.ToString());
Response.End();
}
用watraplion回答修改,但仍然没有回答.. 错误在:
DataTable dt = dt; //Use of unassigned local variable 'dt'

试试这个:
aspx设计视图:
<body>
<form id="form1" runat="server">
<div>
<asp:Table ID="Table1" runat="server">
</asp:Table>
</div>
<div>
<asp:Button ID="btnExport" onclick="btnExport_Click" Text="Export" runat="server">
</div>
</form>
</body>
aspx.cs(代码隐藏)
protected void Page_Load(object sender, EventArgs e)
{
TableRow tr = new TableRow();
TableCell tcel = new TableCell();
tcel.Text = "id";
tr.Cells.Add(tcel);
TableCell tcel1 = new TableCell();
tcel1.Text = "id1";
tr.Cells.Add(tcel1);
Table1.Rows.Add(tr);
}
protected void btn_Click(object sender, EventArgs e)
{
string filename = "ExportExcel.xls";
System.IO.StringWriter tw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
//Get the HTML for the control.
Table1.RenderControl(hw);
//Write the HTML back to the browser.
//Response.ContentType = application/vnd.ms-excel;
Response.ContentType = "application/vnd.ms-excel";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + "");
this.EnableViewState = false;
Response.Write(tw.ToString());
Response.End();
}

首先要说的是,你要做的就是不要导出到excel,但你发送一个带有错误标题的html来欺骗浏览器用excel打开这个内容。
这个解决方案有很多问题,擅长自我会警告用户内容与扩展不同,因为你发送html并且你的响应标题说这是一个excel文件。我可以打赌,客户端上的一些反恶意软件或服务器上的类似软件会阻止此响应,因为提供的内容不同于头文件中声明的恶意软件行为。
使用专用的excel库会更好更容易,例如EPPlus,请查看ASP.NET ashx处理程序,它将DataTable导出到真正的excel文件:
