c中base的用法
c中base的用法的用法你知道嗎？下面小編就跟你們詳細介紹下c中base的用法的用法，希望對你們有用。
c中base的用法的用法如下：
1、調(diào)用基類中的重名方法
[csharp]
public class Person
{
protected string ssn = "444-55-6666";
protected string name = "John L. Malgraine";
public virtual void GetInfo()
{
Console.WriteLine("Name: {0}", name);
Console.WriteLine("SSN: {0}", ssn);
}
}
class Employee : Person
{
public string id = "ABC567EFG";
public override void GetInfo()
{
// Calling the base class GetInfo method:
base.GetInfo();
Console.WriteLine("Employee ID: {0}", id);
}
}
class TestClass
{
static void Main()
{
Employee E = new Employee();
E.GetInfo();
}
}
/*
Output
Name: John L. Malgraine
SSN: 444-55-6666
Employee ID: ABC567EFG
*/
2、調(diào)用基類的構(gòu)造方法
[csharp]
ublic class ActionCancelEventArgs : System.ComponentModel.CancelEventArgs
{
public ActionCancelEventArgs() : this(false) {}
public ActionCancelEventArgs(bool cancel) : this(false, String.Empty) {}
public ActionCancelEventArgs(bool cancel, string message) : base(cancel)
{
this.message = message;
}
public string Message{ get; set;}
}
