Generic
When we look at the term “generic”, unrelated to the programming world, it simply means something that is not tied to any sort of brand name
Generic in C#.net
By using a generic type parameter T you can write a single class that other client code can use without incurring the cost or risk of runtime casts or boxing operations.

Use generic types to maximize code reuse, type safety, and performance.
The most common use of generics is to create collection classes.
The .NET Framework class library contains several new generic collection classes in the System.Collections.Generic namespace. These should be used whenever possible in place of classes such as ArrayList in the System.Collections namespace.
You can create your own generic interfaces, classes, methods, events and delegates.
Generic classes may be constrained to enable access to methods on particular data types.
Information on the types used in a generic data type may be obtained at run-time by means of reflection.
Creating Our First Generic Type
public class Genric_Kartik<K>
{
private K k;
public K Kartik
{
get
{ return k; }
set
{k = value; }
}
}
And on button click I call my generic type, so it depends on you like where you want to assign a value for Ur generic type
protected void Button1_Click(object sender, EventArgs e)
{
Genric_Kartik<string> str = new Genric_Kartik<string>();
Genric_Kartik<int> str1 = new Genric_Kartik<int>();
str.Kartik = “HI REW”;
str1.Kartik = 23423;
Response.Write(str.Kartik);
Response.Write(str1.Kartik);
}
Generic Collections
Collection of a Type that we create, which we used to represent a GenricCollection in our system. Here is the definition for that class:
public class GenricCollection
{
protected string Myname;
protected int Myage;
public string MyName { get { return Myname; } set { Myname = value; } }
public int MyAge { get { return Myage; } set { Myage = value; } }
}
protected void Button1_Click(object sender, EventArgs e)
{
System.Collections.Generic.List<GenricCollection> Kartik = new System.Collections.Generic.List<GenricCollection>();
for (int x = 0; x < 5; x++)
{
GenricCollection GC = new GenricCollection();
GC.MyName = “The Sign OF Success !!”;
GC.MyAge = x;
Kartik.Add(GC);
Response.Write(GC.MyName);
Response.Write(GC.MyAge);
}
}
