Generics refer to the use of type parameters, which provide a way to design code templates that can operate with different data types. Specifically, it is possible to create generic methods, classes, interfaces, delegates, and events.
Generic Methods
In the following example, there is a method that swaps two integer arguments.
static void Swap(ref int a, ref int b)
{
int temp = a;
a = b;
b = temp;
}
To make this into a generic method that can work with any data type, a type parameter first needs to be added after the method’s name, enclosed between angle brackets. The naming convention for type parameters ...
