.NET Web Service & Scokets


I need a web service written in .net. the web service will accept IP address, Port and text message as input.

then, the web service will connect using TCP sockets to the server, send the text message and return the result in JSON format.

The text message must be encrypted. our encryption function was written in Delphi (attach) with your bid let me know if you can rewrite this code in .net. if not, I can write a DLL that will handle the encryption part.

the web service should also send an email to admin in case it encounter any problems with connection.

Attached crypt DLL. function details:
function CryptStr(str, Key : AnsiString; DecryptStr : boolean) : AnsiString;

added stdcall
function CryptStr(str, Key : AnsiString; DecryptStr : boolean) : AnsiString; stdcall;

This DLL should work without memory error.

function CryptStr(str, Key : pchar; DecryptStr : boolean) : pchar; stdcall;

Skills: .NET, ASP, C# Programming
