Defining new data-types

[vbzero]

public class UInt1024
		{
			uint value;

			private UInt1024(uint value)
			{
				//
				// TODO: Add constructor logic here
				//
				if(value < MinValue | value > MaxValue) throw new ArgumentException();
				this.value = value;
			}

			public static implicit operator UInt1024(uint x)
			{
				return new UInt1024(x);
			}

			public static implicit operator uint(UInt1024 x)
			{
				return x.value;
			}
		}

This defines a new data-type UInt1024. At this moment this
only works like as an usual uint32 data-type.

The value is always given as an uint and so the UInt1024
result will also be equal to an uint.

I now want to give the UInt1024 type a 1024-bit register
to manage numbers. So the values have to be in another
format too.

Any ideas to this problem?

thx!
