Fileupload無法在Microsoft IE和Microsoft Edge瀏覽器中使用ASP.NET WebForm

我在VB.NET中有一個代碼只是爲了上傳ASP.NET WebForm中的文件。它在Firefox，Chrome和Safari中完美運行。但是相同的代碼無法將上傳的文件保存在Microsoft Internet Explorer和Microsoft Edge中，但應用程序中沒有任何錯誤或異常。我需要某人的幫助來解決這個問題。我的.aspx代碼和代碼隱藏文件的代碼是如下：Fileupload無法在Microsoft IE和Microsoft Edge瀏覽器中使用ASP.NET WebForm

WebForm1.aspx的

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm1.aspx.vb" Inherits="FileUploadTest.WebForm1" %> 

<!DOCTYPE html> 

<html xmlns="http://www.w3.org/1999/xhtml"> 
<head runat="server"> 
    <title></title> 
</head> 
<body> 
    <form id="form1" runat="server"> 
     <div> 
      <asp:FileUpload ID="Uploader" runat="server" /> 
      <asp:Button ID="cmdUpload" runat="server" Text="Upload" /> 
     </div> 
    </form> 
</body> 
</html>

代碼隱藏文件

Imports System.IO 

Public Class WebForm1 
    Inherits Page 

    Dim uploadDirectory As String = "C:\Uploads\" 
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 

    End Sub 

    Protected Sub cmdUpload_Click(sender As Object, e As EventArgs) Handles cmdUpload.Click 
     Dim uniqueGuid As String = Guid.NewGuid.ToString 

     Dim tmpUploadDirectory As String = uploadDirectory & "\" & uniqueGuid 

     If Not Directory.Exists(tmpUploadDirectory) Then 
      Directory.CreateDirectory(tmpUploadDirectory) 
     End If 

     For Each f As HttpPostedFile In Uploader.PostedFiles 
      f.SaveAs(Path.Combine(tmpUploadDirectory, f.FileName)) 
     Next 
    End Sub 
End Class
