Reserved word Aliased type
sbyte System.SByte
byte System.Byte
short System.Int16
ushort System.UInt16
int System.Int32
uint System.UInt32
long System.Int64
ulong System.UInt64
char System.Char
float System.Single
double System.Double
bool System.Boolean
decimal System.Decimal
Paragraph 21 Because a simple type aliases a struct type, every simple type has members. [Example: For example, int has the members declared in System.Int32 and the members inherited from System.Object, and the following statements are permitted:
int i = int.MaxValue;      // System.Int32.MaxValue constant  
string s = i.ToString();    // System.Int32.ToString() instance method  
string t = 123.ToString();   // System.Int32.ToString() instance method  
end example]
2 The simple types differ from other struct types in that they permit certain additional operations:
