"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Nope, .NET doesn't have multiple inheritance feature as of .NET 1.1

C# supports single class inheritance only.  Therefore, you can specify only one base class to inherit from.  However, it does allow multiple interface inheritance.

TransBindCommented:
An interface looks like a class, but has no implementation.  The only thing it contains are definitions of events, indexers, methods and/or properties.  The reason interfaces only provide definitions is because they are inherited by classes and structs, which must provide an implementation for each interface member defined.


public class DumpTruck: IEngine, IBody
{

void IEngine.Test()
{
Console.WriteLine("This is the Engine TEst");
}
void IBody.Test()
{
Console.WriteLine("This is the Body TEst");
}

Another example for u

1:  //  Multi.cs -
 2:  //-----------------------------------------------------------
 3:
 4:  using System;
 5:
 6:  public interface IShape
 7: {
 8:     // Cut out other methods to simplify example.
 9:     double Area();
10:     int Sides { get; }
11:  }
12:
13:  public interface IShapeDisplay
14:  {
15:     void Display();
16:  }
17:
18:  public class Square : IShape, IShapeDisplay
19:  {
20:     private int InSides;
21:     public  int SideLength;
22:
23:     public int Sides
24:     {
25:        get { return InSides; }
26:     }
27:
28:     public double Area()
29:     {
30:        return ((double) (SideLength * SideLength));
31:     }
32:
33:     public double Circumference()
34:     {
35:        return ((double) (Sides * SideLength));
36:     }
37:
38:     public Square()
39:     {
40:        InSides = 4;
41:     }
42:
43:     public void Display()
44:     {
45:        Console.WriteLine("\nDisplaying Square information:");
46:        Console.WriteLine("Side length: {0}", this.SideLength);
47:        Console.WriteLine("Sides: {0}", this.Sides);
48:        Console.WriteLine("Area: {0}", this.Area());
49:     }
50:  }
51:
52:  public class Multi
53:  {
54:     public static void Main()
55:     {
56:        Square mySquare = new Square();
57:        mySquare.SideLength = 7;
58:
59:        mySquare.Display();
60:     }
61:  }

Output
Displaying Square information:
Side length: 7
Sides: 4
Area: 49
