Passing fixed size array as parameter, ensuring array is proper size

Is there a way to specify the array size when an array is a parameter to a method? e.g.
static void MyMethod(int[] array)
{
    //Array must be exactly 3 elements in size.
}

<example>
int[] array = { -5, -6, -7 };
MyMethod(array);  //OK

int[] array2 = { -5, -6, -7, -8 };
MyMethod(array2); //compiler error

Open in new window

or do I have to construct an entire class consisting of one 3 element int array just so I can ensure the array is the correct size? (I'm guessing I have to go with the class.)

You cannot define the array size for method parameter, inside the method you can check for array size before doing any logic.

But that makes it a runtime error. I was hoping to catch it at compile time.
