Asp.net Telerik AsyncUpload试图重命名文件get IOException

我想重命名我的文件。但我有个例外。它表示该进程无法访问该文件，因为它正被另一进程使用

这是我的代码：

asp.net：

<telerik:RadAsyncUpload ID="rauKachelUpload" runat="server" ChunkSize="0" Localization-Cancel="Löschen" Localization-Remove="Entfernen" Localization-Select="Auswählen"
  Culture="de-DE" Skin="MetroTouch" MaxFileInputsCount="1" OnFileUploaded="rauKachelUpload_FileUploaded">
</telerik:RadAsyncUpload>

无需尝试重命名我的文件，即可正常工作

有人知道我做错了什么吗

谢谢你的阅读。

在尝试重命名文件之前，需要确保fileStream已正确关闭，因为特定文件将由fileStream对象保存。您可以在img.Dispose语句之后尝试fileStream.Close

Protected Sub rauKachelUpload_FileUploaded(sender As Object, e As FileUploadedEventArgs)

    Try
        Using fileStream As Stream = e.File.InputStream
            Using img As System.Drawing.Image = System.Drawing.Image.FromStream(fileStream)
                Dim h As Integer = img.Height
                Dim w As Integer = img.Width
                img.Dispose()
                Dim fileName As String = e.File.GetName()
                If w = MaxWidth And h = MaxHeight Then
                    rauKachelUpload.TargetFolder = "img/kachel_grafik"

                    Dim TimeStamp As String = DateDiff("s", "01/1/1970 12:00:00 AM", DateTime.Now)
                    fileName = "KI_" & TimeStamp & WelcheSparteUndGröße

                    KachelPfad = "~/img/kachel_grafik/" & fileName
                Else
                    KachelFalsch = True
                End If
                If KachelFalsch = False Then

                    e.File.SaveAs(fileName)

                    Page.ClientScript.RegisterClientScriptBlock([GetType](), "CloseScript", "redirectParentPage('VermittlerBearbeiten.aspx?ID=" & VermittlerID & "&KBFN=" & KachelPfad & "&NA=true" & "&fwg=" & WelcheSparteUndGröße & "&Ang1=" & hfAng1CHK.Value & "&Ang2=" & hfAng2CHK.Value & "&Ang3=" & hfAng3CHK.Value & "&Ang4=" & hfAng4CHK.Value & "&AngSrc1=" & hfKachelIMGSrcBaufi.Value & "&AngSrc2=" & hfKachelIMGSrcImmo.Value & "&AngSrc3=" & hfKachelIMGSrcPhoto.Value & "&AngSrc4=" & hfKachelIMGSrcAsse.Value & "');", True)
                Else
                    rnfIconNichtErzeugt.Visible = True
                End If
            End Using
        End Using
    Catch ex As Exception
        rnfIconNichtErzeugt.Visible = True
    End Try

End Sub
