[Mono-devel-list] Exception in small generic c# program

[Martin Willemoes Hansen]

Hello!

When running the program below I get an exception:

using System;
using System.Collections;

class Hello {

	static void Main()
	{
		MyGenericClass<int> foo = new MyGenericClass<int>();
		foo.Generic = 10;
		Console.WriteLine (foo);

		MyGenericClass<string> bar = 
				new MyGenericClass<string>();
		bar.Generic = "Hello, World!";
		Console.WriteLine (bar);

		MyGenericClass<double> baz = 
				new MyGenericClass<double>();
		baz.Generic = 10.5D;
		Console.WriteLine (baz);
	}
}

class MyGenericClass<T> {

	T var;

	public T Generic {
		set { var = value; }
	}

	public override string ToString()
	{
		return var.GetType().ToString();
	}

}

This is the output I get when running the program.
I use Mono Beta1

System.Int32
System.String
 
Unhandled Exception: System.NullReferenceException: A null value was
found where an object instance was required.

Can someone here verify if this a bug?
