Generics and generic collections

Generics: The use of parameterized types to implement multiple data types on the same piece of code. Use the parameterized type to abstract the type for flexible reuse.

Using system;using system.collections.generic;using system.linq;using system.web;using System.Web.UI;using System.web.ui.webcontrols;public partial class fanxing:system.web.ui.page{    protected void Page_Load (object sender, EventArgs e)    {        int obj = 2;        test<int> test = new test<int> (obj);        Label1.Text = "int:" + test.obj;        String obj2 = "Hello World";        test<string> test1 = new test<string> (OBJ2);        Label2.Text = "String:" + test1.obj;    }    Class test<t>           //1,  Test is a generic class. T is the type of paradigm to instantiate. If T is instantiated as an int, then the member variable, obj, is of type int, and if T is instantiated as a string, then obj is the string type.                       {public        T obj;        Public Test (T obj)        {            this.obj = obj;        }    }}
