How can I get the primitive name of a type in C#?

I have the following code in C#:

        Assembly sysAssembly = 0.GetType().Assembly;
        Type[] sysTypes = sysAssembly.GetTypes();
        foreach (Type sysType in sysTypes)
        {
            if (sysType.IsPrimitive && sysType.IsPublic)
                Console.WriteLine(sysType.Name);
        }

This code outputs:

Boolean, Byte, Char, Double, Int16, Int32, Int64, IntPtr, SByte, Single, UInt16, UInt32, UInt64, UIntPtr,

I would like to replace Boolean by bool, Byte by byte and so on when possible, without relying on a fixed array or dictionary. Is there a way to do this?

This is a good answer by Skeet, too

How can I get the primitive name of a type in C#?

The answer is, YOU CAN, and without a dictionary.

Type t = typeof(bool);

string typeName;
using (var provider = new CSharpCodeProvider())
{
  var typeRef = new CodeTypeReference(t);
  typeName = provider.GetTypeOutput(typeRef);
}

Console.WriteLine(typeName);    // bool
