查看override的IL
Override示例
下面我们看一个Override的Example
namespace MyCollection
{
public class MyBase
{
public virtual string Meth1()
{
return "MyBase-Meth1";
}
public virtual string Meth2()
{
return "MyBase-Meth2";
}
public virtual string Meth3()
{
return "MyBase-Meth3";
}
}
class MyDerived : MyBase
{
// 使用 override 关键字重写虚方法 Meth1:
public override string Meth1()
{
return "MyDerived-Meth1";
}
// 使用 new 关键字显式隐藏
// 虚方法 Meth2:
public new string Meth2()
{
return "MyDerived-Meth2";
}
// 由于下面声明中没有指定任何关键字
// 因此将发出一个警告来提醒程序员
// 此方法隐藏了继承的成员 MyBase.Meth3():
public string Meth3()
{
return "MyDerived-Meth3";
}
}
public class VirtualExample
{
public static void Main()
{
MyDerived mD = new MyDerived();
MyBase mB = (MyBase)mD;
System.Console.WriteLine(mD.Meth1());
System.Console.WriteLine(mD.Meth2());
System.Console.WriteLine(mD.Meth3());
System.Console.WriteLine("以上为类MyDerived的显示结果！\n");
System.Console.WriteLine(mB.Meth1());
System.Console.WriteLine(mB.Meth2());
System.Console.WriteLine(mB.Meth3());
System.Console.WriteLine("以上为MyBase的显示结果！\n");
System.Console.WriteLine("按任意键退出...");
System.Console.ReadLine();
}
}
}
