C # Write adapter Mode

1. Create an old class
Public class OldClass
{
Public string [] names = new string [3] {"", "Computer composition principle", "computer architecture "};
}


2. Create a new interface to meet current needs
Public interface INew
{
Void SelectData ();
}
3. Create an adapter to convert the string array in the old class into a generic one;
Public class Adapter: INew
{
Private OldClass data = new OldClass ();
Public void SelectData ()
{
List _ Course = new List ();
_ Course. AddRange (data. names );
Foreach (var a in _ Course)
{
System. Console. WriteLine ();
}
System. Console. ReadLine ();
}
}
4. Call the output in the main function;
Class Program
{
Static void Main (string [] args)
{
INew _ new = new Adapter ();
_ New. SelectData ();
}

}
