What you really want is to compute the result, isn't it?

Why do you want to use String if you can declare f as int?
It will make that code easier.

PS. Why do you want to make it like that by the way?

C#

string f = "A=(C*D)+(L*K)*B";
f =  f.Replace("C", "10"); // replace for each character like this

To solve your problem, you could use a lookup table:

C#

Dictionary<string,> dictionary = new Dictionary<string,>();
	dictionary.Add("C", 10);
	dictionary.Add("D", 12);
        dictionary.Add("L", 14);
        dictionary.Add("K", 15);
        dictionary.Add("B", 13);

And then in a loop to change all letters to numbers

C#

if (dictionary.ContainsKey("С"))
{
    int value = dictionary["С"];
}

Good luck!
