[Solved] C# – No overload for method “getal” takes 1 argument


The error is saying there’s not method getal that has a string parameter.

You’re invoking getal with txtNumber.text (string) as argument and the compiler is looking for a getal method with a string parameter and can’t find it. The existing getal method doesn’t take any parameters.

public int getal(string x)
        {
            _a += _a;
            return _a;
        }

Of course you still need to define what you are going to do with the string parameter “x” defined in getal but now it compiles.
