C++ to C# porting

How can I port this code (c++) to c#?

template <class entity_type>
class State {
public:
    virtual void Enter(entity_type*) = 0;
    virtual void Execute(entity_type*) = 0;
    virtual void Exit(entity_type*) = 0;
    virtual ~State() { }
};

Assuming that really is a purely abstract base class, which is what it looks like:

interface State<T>
{
    void Enter(T arg);
    void Execute(T arg);
    void Exit(T arg);
};

The exact argument passing convention is awkward though. Without knowing exactly what you want to do it is hard to say exactly what you should do in C#. Possibly, void FunctionName(ref T arg) might be more appropriate.

public abstract class State<entity_type>
    {
        public abstract void Enter(entity_type obj);
        public abstract void Execute(entity_type obj);
        public abstract void Exit(entity_type obj);
    }

This seems to work :D

you can write like this

abstract class State<T> : IDisposable where T : EntityType
{
    public abstract void Enter(T t);
    public abstract void Execute(T t);
    public abstract void Exit(T t);

    public abstract void Dispose();
}

fix your T to EntityType class.

Some thing of the sort:

interface State<T> : IDisposable
{
    void Enter(T t);
    void Execute(T t);
    void Exit(T t);
}
