End Sub

解决方案

< blockquote>



无论你编写的代码是否正确，我都没有检查你的代码。可能是Path中的问题。



ex：



Image1.ImageUrl = @〜/ + YourPath;

The following code I use to show image in an image control but it can not show image,How can I solve this problem.

Protected Sub UploadButton_Click(sender As Object, e As EventArgs)
If FileUploadControl.HasFile Then
Try
Dim filename As String = Path.GetFileName(FileUploadControl.FileName)
FileUploadControl.SaveAs(Server.MapPath("~/") & filename)
temp = "~/" & filename
StatusLabel.Text = "Upload status: File uploaded!"
Image1.Visible = True
Image1.ImageUrl = temp
Catch ex As Exception
StatusLabel.Text = "Upload status: The file could not be uploaded. The following error occured: " + ex.Message
End Try
End If
End Sub

解决方案

hi,

Whatever the code you written seems correct, i didn''t checked your code. may be the problem in Path.

ex:

Image1.ImageUrl = @"~/" + YourPath;
