Question

有人能告诉我这段代码有什么问题吗？我正在尝试使用这段代码上传一个mp3，当我尝试这样做时，我得到一个“Internet Explorer无法显示网页”

<asp:FileUpload ID="FileUpload1" runat="server" />

<asp:Button ID="upload" runat="server" Text="GO" OnClick="btn_Click" /><br /><br />
<asp:Label ID="Label1" runat="server"></asp:Label>
<script runat="server">
protected void btn_Click(object sender, EventArgs e)
{
    if (FileUpload1.HasFile)
    {
        string fileExt =
           System.IO.Path.GetExtension(FileUpload1.FileName);

        if (fileExt == ".mp3")
        {
            try
            {
                FileUpload1.SaveAs(Server.MapPath("~/Uploads/" +
                   FileUpload1.FileName));
                Label1.Text = "File name: " +
                    FileUpload1.PostedFile.FileName + "<br>" +
                    FileUpload1.PostedFile.ContentLength + " kb<br>" +
                    "Content type: " +
                    FileUpload1.PostedFile.ContentType;
            }
            catch (Exception ex)
            {
                Label1.Text = "ERROR: " + ex.Message.ToString();
            }
        }
        else
        {
            Label1.Text = "Only .mp3 files allowed!";
        }
    }
    else
    {
        Label1.Text = "You have not specified a file.";
    }
}



    </script>

使用web.config中的以下内容增加http maxRequestLength - 它应该可以正常工作。默认情况下它限制在4mb。

<system.web>
  <httpRuntime executionTimeout="240" maxRequestLength="20480" />
</system.web>
