How to shorten boolean function

I have to shorten boolean function to one line. I'm a begginer in C# and I have no idea, how to shorten it.

    static bool mod(int number) 
    {
        if (number % 3 == 0)
        {
            return true;
        }
        else
        {
            return false;
        }
    }

Use simply number % 3 == 0, either inline, or as the function body. If you do retain it as a function then do consider renaming the function to mod_by_3 or similar.

In C and C++ you can ace it with the considerably clearer !(number % 3).

I'm the winner? Expression bodied functions are new in C#6

static bool Mod(int number) => number % 3 == 0;

Just return the expression inside the if-statement:

static bool mod(int number) 
{
    return number % 3 == 0;
}

You want this: 

static bool mod(int number){    
   return number % 3 == 0;
}
