The predefined types in C# are:

Unsigned integer (
byte,ushort,uint,ulong) -
Real number (
float,double,decimal)
-
-
Logical (
bool) -
Character (
char)
-
- Reference types
-
String (
string) -
Object (
object)
-
Predefined types in C# alias Framework types in the System namespace. There is only a syntactic
difference between these two statements:
int i = 5; System.Int32 i = 5;
The set of predefined value types
excluding decimal are known as
primitive types in the Common Language Runtime
(CLR). Primitive types are so called because they are supported directly via instructions in compiled
code, which usually translates to
direct support on the underlying processor.
