// create a dictionary

How do you pass arrays -- specifically, an array of integers of unknown length -- as arguments to methods in C#?

void MyFunction(int[] myarray)
{ }

int[] arr = {2,4,6};
MyFunction(arr);

void MyFunction(params int[] myarray)
{ }

int[] arr = {2,4,6};
MyFunction(arr);

MyFunction(2,4,6);

int[] someArray = new int[] { 1, 2, 3 };
someMethod(someArray);

public void someMethod(int[] arrayArgument) {
   Console.WriteLine(arrayArgument.Length.ToString());
}
