Converting String to Int32 Trouble

Question

I'm having trouble converting an string to Int32 when calling it. This is what I'm struggling with.

public static int GetProgramLength()
{
    Console.WriteLine("Please enter program length:");
    return Int32.TryParse(Console.ReadLine);
}

Its telling me,

No overload for method, "Try Parse" takes 1 argument.

I already fixed the () after the readline, I just forgot to put it on here. — Kevin Ware, Dec 10 '15 at 04:23

You need to specify the out value to use Int32.TryParse() the result of TryParse is stored to the out parameter(outParam will be 0 if it failed to convert the input string),and also it will return a boolean value to indicate whether the conversion is success or a failure;

So you have to correct your code as like the following:

int outParam=0;
Console.WriteLine("Please enter program length:");
Int32.TryParse(Console.ReadLine(),out outParam);
return outParam;

Or, since the result of the Try is not being checked, just use `.Parse()` — Erik Funkenbusch, Dec 10 '15 at 05:30
