Class Inheritance

Gareth_Hastings

I'm just starting to get my teeth in to C# and so far I think its going quite well. I used to do quite a bit of coding in Delphi which brings me on to my current problem. In Delphi you used to be able to create your own class using a Thread class as its base example: -------------------------------- TMyClass = Class(TThread) .... Public FVariable : string; End; Var MyClass : TMyClass; MyClass := TMyClass.Create(True); MyClass.FVariable := 'Test'; -------------------------------- MyClass now has all the functions/procedures and variables of a normal thread class. I would like to do the same thing in C# but I can't inherit from system.threading.thread because it's sealed. I suspect there might be another approach to this but I can't find much on google. I guess I am not searching for the right things here. I guess I'm trying to do this the Delphi way when I should be doing them the C# way!!! Any ideas anyone? Thanks

In C# threads are handled differently. You create an instance of System.Threading.Thread and pass ThreadStart delegate to the constructor. ThreadStart delegate represents a method that thread will run.

public static void RunMe()
{
{
//Run code here
}
}

public static Main()
{
Thread myTread = new Thread(new ThreadStart(RunMe));
}

If you are looking for the syntax of classes for C#, the following is a simple example:

public class TrafficLight
{
// constructor
TrafficLight(){}

// private variable
private Color \_color; 

// public property
public Color LightColor
{
   get{return \_color;}
   set{\_color = value;}
}

public virtual void ChangeColor(Color newColor)
{
    LightColor = newColor;
}

}

public class DeluxeLight : TrafficLight
{
// constructor
DeluxeLight(){}

public overrides void ChangeColor(Color myColor)
{
   //.... overriding the base class method
}

}
