I've given my self a little project, a) to get my teeth back into programming and b) to issue a http request via a proxy server in C# so that our internet connection at work does not time out.

firstly is this possible in C#? I've seen lots of tutorials on socket programming, and not one was of help, most were all unix/linux bassed, written bt anti microsoft poeple in the early 90's. can any one offer me a decent tutorial for socket programming with my mingw32 compiler and will i need extra header files??

answers on a postcard please

muffdust: Try the help file/msdn library that comes with Visual Studio .NET

It has very good examples and detailed explaination. Admittedly the examples are in VB.NET but its not hard to convert it to C#.

You'll probably want to look at the Socket class - Overview which has an Example for making a HTTP request via a TCP connection.

Wish you were here....

PS: You might want to check out http://www.codeproject.com/buglist/udpclientbug.asp which reports a bug with Socket.Available and UDPClient.Receive.

The front of this postcard shows a snapshot of the squid web proxy source code. The reverse bears this missive:

There's no reason why it shouldn't be possible in C#; the .Net framework has a set of classes for doing sockets stuff, and it might even have a class or two that will pull down a file over http, through a proxy. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlr... is a good point for you to start looking at such things.

However. Mingw32 is not, nor has it ever been, a C# compiler. I believe it has C, C++, and whatever else gcc supports these days. If you want to use C#, get the .Net SDK from microsoft.

If you want to use Mingw32, a suitable tutorial would be http://www.ecst.csuchico.edu/~beej/guide/net/html/ - it has a note on getting stuff to work with windows.

Or get Mono from go-mono.org!

thanks.. since I've posted I've got a copy of visualstudio.net on my work computer so I think I'll give it a try with that.
