Introduction
We can use Microsoft SOAP protocol to transfer any files between a client and a server. It's easy through firewall and also it is cross flatform.
Background
I was going to develop a mobile software for Pocket PC but I found there were not enough resouces to use on mobile operating system. Finally, I found Web services can solve the problem.
Using the code
There are two parts on the sample which includes: a Windows client and Webservice server code. Both of these source codes are listed below.

public string WriteBinarFile(byte[] fs, string path, string fileName)
{
try
{
MemoryStream memoryStream = new MemoryStream(fs);
FileStream fileStream = new FileStream(path + fileName, FileMode.Create);
memoryStream.WriteTo(fileStream);
memoryStream.Close();
fileStream.Close();
fileStream = null;
memoryStream = null;
return "File has already uploaded successfully";
}
