c# generics

generics to write a class or method that can work with any data type. When the compiler encounters a constructor for the class or a function call for the method, it generates code to handle the specific data type.

It helps you to maximize code reuse, type safety, and performance

·         Use generic types to maximize code reuse, type safety, and performance.

·         The most common use of generics is to create collection classes.

public class GenericList

{

    public void Add(T input) { }

}

class TestGenericList

{

    private class ExampleClass { }

    static void Main()

    {

        // Declare a list of type int.

        GenericList list1 = new GenericList();

        list1.Add(1);

        // Declare a list of type string.

        GenericList list2 = new GenericList();

        list2.Add("");

        // Declare a list of type ExampleClass.

        GenericList list3 = new GenericList();

        list3.Add(new ExampleClass());

    }

}
