Generic classes with more example in c#

Generic classes provide generic nature to classes and data member datatypes. When creating Generic classes we will create classes, data members ... we will define with place holders <>
Class classname <Placeholder>
{
...
}
While creating object for the generic class we will specify the data type, then onwards class will bind to specific data type

classname<int> obj = new classname<int>();

Example

public class Generic<T>
{
// Data Member
T empID;

// Constructor
public Generic(T eVal)
{
empID = eVal;
}

public void Show()
{
Console.WriteLine("Employee Id - {0}", empID);
}

}

public class MainClass
{
public static void Main()
{
Generic<int> genObj1=new Generic<int>(20);
genObj1.Show();
Generic<string> genObj2=new Generic<string>("EMP1");
genObj2.Show();
}
}


In the above example while we are creating instance, if we pass the place holder value then the class will be created in the inline memory withe the specified type.
