i am trying to make a program in c# based off another program that was written in java i would like to know if anyone nows what syntax you use to link other source files to your program.
in other words the c# equivalent to java's import code.

Overview
Java Language Conversion Assistant is a tool that automatically converts existing Java-language code into Visual C#® for developers who want to move existing applications to the .NET Framework.

Java Language Conversion Assistant provides developers using Visual Studio .NET 2003 a quick, low-cost method of converting Java-language applications to Visual C# and the .NET Framework. These applications can then be extended to utilize XML Web services and the complete .NET developer platform, including ASP.NET, ADO.NET, and Microsoft Windows® Forms.

This is a blurb from Microsoft, the software is a free download from them. Should give you a clue about the import question.

thank you.
