Constant initialing problem

Question

const int Value = 541564; // Works without problem.
But when I tried this...
const int Value = Convert.ToInt32(Console.ReadLine());
I got this error : The expression being assigned to 'Value' must be constant.
So it means Console.ReadLine() isn't a constant but 541564 is.
Then I tried this one:
int InitialValue1 = Convert.ToInt32(Console.ReadLine());
const int Value = InitialValue1;
Again the same error.
This also won't work:
int InitialValue2 = 5343543;
const int Value = InitialValue2;
Any idea about why cannot assign a constant using user input.
Is there a way to solve this??
I asked this question because I am curious to know why :)
Thanks!!

Answer 1

Constants are something that you set and then it stays the exact same. What you're wanting is a variable, not a constant. Variables can be changed and can accept user input.

For example:

private const float pi = 3.141592;

The value of pi never changes. It's always the same. As such, you can easily assign that value to a constant and then can use it as needed. If you're changing, convert, doing anything other than setting a constant value, then use a variable instead.
