摘要:C# override 改寫tostring

這個範例實作了employee類別的多載，並用override 改寫了tostring

因為id,name 是private，所以我們再建立一個建構函式public Employee(string id, string name)

來達成多載的目的，使得employee可以在宣告後，直接將id name的值給employee

以下是employee.cs


	public class Employee
    {
        private string id;
        private string name;
        public Employee()
        {            
        }
        public Employee(string id, string name)
        {
            this.id = id;
            this.name = name;
        }    
        public override string ToString()
        {
          //  return base.ToString();
            return "編號:" + id +",姓名"+name;
        }
    }

以下是MainWindow.xaml.cs


	private void button1_Click(object sender, RoutedEventArgs e)
        {
            Employee john = new Employee("1","JOHN");
            Employee andy = new Employee();
            label1.Content = john.ToString();
            label2.Content = andy.ToString();
        }
