C# Primitive Data Types.

primitive type is a data type in c# language which is understandable by the C# compiler . in C# int , string , float etc... data types are considered as primitive types . during compilation usually primitive types are converted into MSIL types.

Ex: if you write int x=20 ; in C# language during compilation the code is converted as shown below .

Int32 x=20;

Note: Int32 is MSIL equivalent for int primitive type . question copied from below weblink .
