Re: How is this conditional able to execute?

I only put the values that way to show what they are. I wasn't actually
assigning anything.

This code is in a loop. Most of the time, returndata is the empty string.

networkStream = tcpClient.GetStream()
Dim bytes(tcpClient.ReceiveBufferSize) As Byte
networkStream.Read(bytes, 0,
tcpClient.ReceiveBufferSize)
Dim returndata As String =
Trim(Encoding.UTF8.GetString(bytes))

If returndata.ToString <> "" And returndata.ToString
<> ClientForm.ReturnData Then
ClientForm.ReturnData = returndata
returndata = Nothing
Else
End If
End If

bytes always has a length of 8193. Up until about the 35th element of its
array, the values are non zero. After that they are all zero. Possibly I'm
not seeing something that is kept in bytes when I assign it to returndata?
Although returndata appears to be the empty string, it may have some other
value.
