Transfer any files on Web services by c#

[subcom]

Introduction
We can use Microsoft SOAP protocol to transfer any files between client and server.It's easy through firewall and also it cross flatform.

Background
I was going to develop an mobile software on pocket pc,but I found there were tiny resouces to use on mobile operating system.finally,I was finding Web services can solve the problem.

Using the code
There are two parts on the sample which included: Windows client and Webservice server code.

Blocks of code should be set as style "Formatted" like this:

{
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。";
}

please use code tags when posting code..

before you do, there's not much chance anyone will help you

True the person should use code tags. But I don't think they are looking for any help. They are just giving a sample for people to look at and hopefully learn from (and a bit of advertising as well...).

heh, my point exactly... I didn't even read his post.. just looked at all that text floating around and figured I'd tell him about the wonders of code tags
