Actions and Func Objectives
Challenge Task 1 of 3
In the Program class, declare a public Func field named Square that takes an int and returns an int. Use an anonymous method to assign a delegate that takes an int parameter named number and returns the result of number * number.
My attempt #1:
using System;
namespace Treehouse.CodeChallenges { public class Program { public Func<int,int> Square = delegate(int number) { return number * number; }; } }
When checking work:
Bummer! Did you declare a Func that takes an 'int' and returns an 'int'?
My attempt #2:
using System;
namespace Treehouse.CodeChallenges { public class Program { Func<int,int> Square = delegate(int number) { return number * number; }; } }
Bummer! Did you declare a 'public Func'?
using System;
namespace Treehouse.CodeChallenges
{
public class Program
{
Func<int,int> Square = delegate(int number)
{
return number * number;
};
}
}

you need to separate the <int,int> like this;
public Func<int, int>

I think your first attempt was the closest :)
The challenge engine it seems is really fussy on this one ... I used your code ... and the check work return information
Bummer! Did you declare a 'public Func'?
// make it public and for syntactic craziness separate your argument and return type
// i.e. public Func<int, int>
Func<int,int> Square = delegate(int number)
{
return number * number;
};
Nice work (crazy checking requirement aside)
