Question

我想根据相应的链接按钮ID在新窗口中打开我上传的文档。文档以DB中的完整路径保存。

<asp:LinkButton ID="lnkstdres" runat="server" Text='<%#Eval("Alias") %>' CommandArgument='<%#Eval("Idinst") %>' CommandName="StudentRes" OnClick="lnkstdres_Click"></asp:LinkButton>  

protected void lnkstdres_Click(object sender, EventArgs e)
    {

    }

我不知道该怎么做。谢谢

Answer 1

if( ( File1.PostedFile != null ) && ( File1.PostedFile.ContentLength > 0 ) )
{
    string fn = System.IO.Path.GetFileName(File1.PostedFile.FileName);
    string SaveLocation = Server.MapPath("Data") + "\\" +  fn;
    try
    {
        File1.PostedFile.SaveAs(SaveLocation);
        Response.Write("The file has been uploaded.");
    }
    catch ( Exception ex )
    {
        Response.Write("Error: " + ex.Message);
        //Note: Exception.Message returns a detailed message that describes the current exception. 
        //For security reasons, we do not recommend that you return Exception.Message to end users in 
        //production environments. It would be better to put a generic error message. 
    }
}
else
{
    Response.Write("Please select a file to upload.");
}

我正在为我的问题发布解决方案。

var name = prompt("What's your name?");
if (name === '') {
    name = prompt("Try again");
alert(name);
}
