推荐答案

在aspx文件中:

<asp:FileUpload ID="FileUpload1" runat="server" />
         <asp:Button ID="Button1" runat="server" Text="Upload" 
            onclick="Button1_Click" />
            <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>

在后面的代码中:

protected void Button1_Click(object sender, EventArgs e)
{
    string filename = Path.GetFileName(FileUpload1.FileName);
    FileUpload1.SaveAs(Server.MapPath("~/") + filename);
    Label1.Text = "Upload status: File uploaded!";
}
