immutability - How to declare a local constant in C#?

Question

How to declare a local constant in C# ?

Like in Java, you can do the following :

public void f(){
  final int n = getNum(); // n declared constant
}

How to do the same in C# ? I tried with readonly and const but none seems to work.

Any help would be greatly appreciated.

Thanks.

Answer 1

In C#, you cannot create a constant that is retrieved from a method.

A constant expression is an expression that can be fully evaluated at compile time.
