Brick Wall script doesn't work.

Unity Engine
1

So the manual (http://unity3d.com/support/documentation/Manual/Instantiating%20Prefabs.html) gives me this script:

So I copied it and changed it into this because I did it in C#:

for(int y=0; y<5; y++)
		{
			for(int x=0; x<5; x++)
			{
				GameObject cube = GameObject.CreatePrimitive(PrimitiveType.Cube);
				cube.AddComponent(Rigidbody);
				cube.transform.position = Vector3(x,y,0);
			}
		}

And the errors I get are these:

Assets/Scripts/brick_wall.cs(12,51): error CS0119: Expression denotes a type', where a variable’, value' or method group’ was expected

Assets/Scripts/brick_wall.cs(12,38): error CS1502: The best overloaded method match for `UnityEngine.GameObject.AddComponent(string)’ has some invalid arguments

Assets/Scripts/brick_wall.cs(12,38): error CS1503: Argument #1' cannot convert object’ expression to type `string’

Assets/Scripts/brick_wall.cs(13,59): error CS0119: Expression denotes a type', where a variable’, value' or method group’ was expected

What’s going on?

Is there no help to be had with this issue?

		for(int y=0; y<5; y++)
		{
			for(int x=0; x<5; x++)
			{
				GameObject cube = GameObject.CreatePrimitive(PrimitiveType.Cube);
				cube.AddComponent<Rigidbody>();
				cube.transform.position = new Vector3(x,y,0);
			}
		}

Thank you Alienchild, that worked.
