fileupload控件

 ASP网页中的代码:

 <form id="form1" runat="server">
    <div>
   
        <asp:FileUpload ID="FileUpload1" runat="server" /><br />
        <asp:FileUpload ID="FileUpload2" runat="server" /><br />
        <asp:FileUpload ID="FileUpload3" runat="server" /><br />
        <asp:FileUpload ID="FileUpload4" runat="server" /><br />
        <asp:Button ID="Button1" runat="server" Text="上传" onclick="Button1_Click" />
        <asp:Label ID="Label1" runat="server" Text=""></asp:Label>

    </div>
   
    </form>

方法中代码:

 protected void Button1_Click(object sender, EventArgs e)
    {
        string filepath = Server.MapPath("~/upload");
        HttpFileCollection uploadFile = Request.Files;
        Label1.Text = "";
        for (int i = 0; i < uploadFile.Count; i++)
        {
            try
            {
                HttpPostedFile userpostfile = uploadFile[i];
                if (userpostfile.ContentLength > 0)
                {
                
                    Label1.Text += "<u>文件#" + (i + 1) + "</u><br/>";
                    Label1.Text += "文件内容类型" + userpostfile.ContentType + "<br/>";
                    Label1.Text += "文件大小" + userpostfile.ContentLength + "<br/>";
                    Label1.Text += "文件名" + userpostfile.FileName + "<br/>";

                    userpostfile.SaveAs(filepath + "\\" + Path.GetFileName(userpostfile.FileName));
            //userpostfile.FileName 如果这种方法不行,并不是代码的问题,而是浏览器的问题,改一下兼容模式就好了,因为有的浏览器
                    //提交的方式不同,有的只是提交filename,而有的却是把整个路径全部提交上去,所以会报错.
                }
            }
            catch (Exception ex)
            {
                Response.Write(ex.ToString());
            }
        }

    }
