[C# ] 繼承的使用範例 - class

繼承


範例:

	using System;
	using System.Collections.Generic;
	using System.Linq;
	using System.Text;
	using System.Threading.Tasks;
	namespace Test
	{
	class Program
	{
	static void Main(string[] args)
	{
	inher testInher = new inher();
	Console.Read();
	}
	}
	class ExampleClass
	{
	public ExampleClass()
	{
	Console.WriteLine(" 00 message of ExampleClass: in class ExampleClass()");
	}
	}
	class inher : ExampleClass
	{
	public inher()
	{
	Console.WriteLine(" 01 message of inher(): in class inher : ExampleClass");
	}
	}
	}
	//==============================
	// run result as following:
	//==============================
	// 00 message of ExampleClass: in class ExampleClass()
	// 01 message of inher(): in class inher : ExampleClass

執行結果:

 00 message of ExampleClass: in class ExampleClass()
 01 message of inher(): in class inher : ExampleClass

可以看到，當透過 new 實體化 testInher 變數時候，會依序執行 建構式 ，
因此會出現上列message
