how would i make it so if i type "x" "x" will happen

meper

I'm trying to make a simple calculator so when I type a, s, m, or d it would go to the method I want it to go to but when I try to write "if ( a = Console.ReadLine()) {Addition();} it just says "Cannot implicitly convert type 'string' to 'bool'" but how would I do that?

here is my code

static void Start()

        {    

            string a = "a";

             Console.Write("type a for addition, s for subtraction, m for multiplication, or d for division: ");

             if ( a = Console.ReadLine() );

            {

                Addition();

            }

        }

im mostly just trying to say how would i use whatever i typed in an if statement

edit -i got it to work :)

static void Start()

        {   

            string asmd;

            string a = "a";

            string s = "s";

            string m = "m";

            string d = "d";

            

             Console.Write("type a for addition, s for subtraction, m for multiplication, or d for division: ");

            asmd = Console.ReadLine();

            if (asmd == a)

            {

                Addition();

            }

            else

            {

                Start();

            }

            if (asmd == s)

            {

                Subtraction();

            }

            else

            {

                Start();

            }

            if (asmd = m)

            {

                Multiplication();

            }

            else

            {

                Start();

            }

            if (asmd == d)

            {

                Division();

            }

            else

            {

                Start();

            }

        }

You could have just written the chars under "" (say, "a" for addition) and checked directly instead of declaring so many variables (which is extremely memory inefficient).
