Applications in. net

The most obvious application of the template method mode is tostring (). We know that all objects in. Net inherit from the object, and the object has a tostring method. The specific object can implement its own tostring method.

Public class persons
Public String firstname {Get; set ;}
Public String lastname {Get; set ;}

Public override string tostring ()
Return string. Format ("{0} {1}", firstname, lastname );

class Program
{< br> static void main (string [] ARGs)
{< br> Persons P = new persons ();
P. firstname = "Li";
P. lastname = "Sheng";
system. console. writeline (P. tostring ();
system. console. readkey ();
}< BR >}
