If a method in a class has a const variable such as:
public void MyMethod()
{
const int myVariable = 5;
// blah
}
will myVariable be initialized only once (when the method is called for the first time I believe) or everytime the method is called ?
Neither. Never. Constant are used primarily at compile time. It isn't a variable nor a field. The literal value 5 will be used by any code that uses the constant ("ldc.i4.5") - but the constant itself isn't needed for that at runtime.
Never. What will happen is that the compiler will burn in that variable into the method: as if it never existed, and just put the value where you put the const's name.
e.g.
public double MyMethod()
{
const int anInt = 45;
return anInt * (1/2.0) + anInt;
}
will get compiled to:
public double MyMethod()
{
return 45 * (1/2.0) + 45;
//actually that would also be calculated at compile time,
//but that's another implementation detail.
}
