Using remoting to implement file transfer

Because the job needs to write a file transfer stuff
Using the System.Runtime.Remoting
Client Interface classes:
Namespace Nail.Net.Remoting.Trans
Public Interface Itransfile
Function SendFile (ByVal FileName as String, ByVal bytes () as Byte, ByVal CLIENTCRC As Integer) As Integer
Function Comparefile (ByVal FileName as String, ByVal CLIENTCRC as Integer) as Boolean
Function Getfiledet (ByVal FileName as String) as Integer
Function GetFileInfo (ByVal FileName as String) as Byte ()
Function GetFileInfo (ByVal FileName as String, ByVal Length as Integer) as Byte ()
Function GetFileInfo (ByVal FileName as String, ByVal Point As Integer, ByVal Length as Integer) as Byte ()
Property Servertranssavefilepath () as String
Property Servertempfilepath () as String
End Interface
End Namespace
Client class: (Implementation of File transfer here) (with 1 forms after the form code I'll post it) (please add a reference System.Runtime.Remoting. NET default is the server-side class that is not referenced)
