Solution 1

Look at your code:

C#

static int Getanswer(char answer)
    {
    string result;  
    ...
    return result;
    }

Your method is defined as returning an integer, but you are explicitly telling it to return a string. You can't do that: change the definition of the method to return a string and that'll fix it:

C#

static string Getanswer(char answer)
    {
    string result;  
    ...
    return result;
    }
