Example: generic method c#

//Swaps the lhs and rhs variables. T is a type given as an argument 
//and can be used in the method like a type. (It doesn't have to be "T", it can
//be anything).

static void Swap<T>(ref T lhs, ref T rhs)
{
    T temp;
    temp = lhs;
    lhs = rhs;
    rhs = temp;
}

public static void TestSwap()
{
    int a = 1;
    int b = 2;

    Swap<int>(ref a, ref b);
    System.Console.WriteLine(a + " " + b);
