No one can give you solutions unless you give the exact details of when this occurs, including details of the file and the code that you are using.

Dim fileStream As New IO.FileStream(mapPath & "\" & filename, FileMode.OpenOrCreate)
If (fileStream.Length) > 50000 Then
System.Web.HttpContext.Current.Response.Write("{success:false, errmsg:'File size is large imagesize}")
Exit Sub
End If

thank u for suggestion its very useful for me... i have found the solution with the help of ur code... and also i have done with some extra lines of code that is...

Dim inputStream As Stream = HttpContext.Current.Request.InputStream
inputStream.CopyTo(fileStream)

After execution of these lines.. we can get the length of the file...

Thank u friend.....

You are probably trying to re-open the filestream, try this.

VB

Dim fileStream As New IO.FileStream(mapPath & "\" & filename, FileMode.OpenOrCreate)
    If (fileStream.Length) > 50000 Then
    System.Web.HttpContext.Current.Response.Write("{success:false, errmsg:'File size is large imagesize}")
    fileStream.Close() 'Be sure to close the filestream.
    Exit Sub
End If

Good luck.
