How to create a DLL in C language?

Answer 1

Creating a simple C# application:

1. Start Visual Studio .NET.
2. Go to File->New->Project.
3. Select Visual C# Project. From the �Templates�, you can either select �Console Application�, or an �Empty Project� just like it was described above.
4. Give the name to your application.
5. Press OK.

Into the specified class, insert the following two lines: Collapse | Copy Code

[DllImport("TestLib.dll")] public static extern void DisplayHelloFromDLL ();

In C#, keyword extern indicates that the method is implemented externally.

Your code should look something like this: Collapse | Copy Code

using System; using System.Runtime.InteropServices; // DLL support class HelloWorld { [DllImport("TestLib.dll")] public static extern void DisplayHelloFromDLL (); static void Main () { Console.WriteLine ("This is C# program"); DisplayHelloFromDLL (); } }

Please, note that System.Runtime.InteropServices is required for operations with the DLL.

(The answer in very good, the question is wrong.)
