我有一个类型文件的输入,当我尝试执行请求时。文件在更新面板中包裹时,它总是返回一个空的httpfilecollection。为什么???
这是CodeBehind :(在httpcontext.current.request.files ...始终为0。)
Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
Dim uploads As HttpFileCollection
uploads = HttpContext.Current.Request.Files
For i As Integer = 0 To (uploads.Count - 1)
If (uploads(i).ContentLength > 0) Then
Dim c As String = System.IO.Path.GetFileName(uploads(i).FileName)
Try
uploads(i).SaveAs("C:\UploadedUserFiles\" + c)
Span1.InnerHtml = "File Uploaded Sucessfully."
Catch Exp As Exception
Span1.InnerHtml = "Some Error occured."
End Try
End If
Next i
End Sub
此示例来自ASP.NET网站...但是我的应用程序非常相似。
没有正确的解决方案
