A constant field or local variable can be initialized with a constant expression which must be fully evaluated at compile time. void Calculate(int Z) {   const int X = 10, X1 = 50;   const int Y = X + X1; //no error, since its evaluated a compile time   const int Y1 = X + Z; //gives error, since its evaluated at run time } You can apply const keyword to built-in value types (byte, short, int, long, char, float, double, decimal, bool), enum, a string literal, or a reference type which can be assigned with a value null. const MyClass obj1 = null;//no error, since its ev...
