Example C# NET library

One advantage of the NET environment is that you can mix the compiled object files from different languages to one program. To test this we use a small class definition that is written in C#, compile it to a library and use this to show how to access the parts of the class definition from within a HBasic program.

C# program (library)

SInce this program has no entry point we will call it a library. Apart from the missing entrypoint there are no other differences between a normal program and a library.

You can find the sourcecode for this example in the code_examples/csharp folder of yout HBasic directory. The example program is called csharp_class_example.cs. To create a compiled library from it compile it with the NET compiler with

cscc -shared -o FooBar.dll csharp_class_example.cs

or create a csharp project in HBasic, load the sourcecode and insert

-shared -o FooBar.dll

into compiler options of project.


using System;

namespace FooBar;
{
   public class MyClass
   {
      /* Example of constructor method. */

      public MyClass()
      {
         Console.WriteLine( "Constructor of MyClass" );
      }
   
      /* Const value. */
      public const int MyConst = 12;

      /* Field */
      public int MyField = 34;
      public int Field2 = 444;

      /* Method. */
      public int getval()
      {
         return( 1234 );
      }

      /* Property. */

      public int MyProperty
      {
         get 
         {
             return MyField;
         }
         set 
         {
            MyField = value;
         }
      }

      /* Event definition. */

      public event EventHandler MyEvent;

      /* Enum definition. */
      public enum myenum 
      {
         val1 = 3, 
         val2 = 8
      }
   }
}
Example FooBar.cs: C# class definition that should be instantiated in HBasic.

After you have created the compiled library FooBar.dll you may include FooBar.dll into your HBasic project with the package editor.
