Indeed it is; I'm not sure why you're confused about this when a
one-line C# program will give you the answer :-)  typeof(int) is
converted by the C# compiler into the following IL:

ldtoken    [mscorlib]System.Int32
call       class [mscorlib]System.Type [mscorlib]System.Type::GetTypeFromHandle(valuetype [mscorlib]System.RuntimeTypeHandle)

which makes it pretty clear that System.Int32 is specified at compile
time.

No; however there are several common interfaces these types implement,
such as IConvertible.
