Is there a simple way to determine type size in C#?

Is there a way to say something like:

sizeof(type)? Or type.Size?

Right now I am looking at using code like:

if (type.Equals(typeof(int)))
    return sizeof(int);
else if (type.Equals(typeof(long)))
    return sizeof(long);

etc, etc, for every single data type.

There must be an cleaner solution, no?

Maybe you can go Convert.ToString(type.MaxValue, 2).Length / 8 ?

Try Marshal.SizeOf()

If this is for data access, you can do type.GetTypeCode() (which is a member of IConvertible), which gives you a nice enum to switch on.
