C#如何使用接口

public interface IMyInterface
{
    void MyMethod();
    int MyProperty { get; set; }
    event EventHandler MyEvent;
}

public class MyClass : IMyInterface
{
    public void MyMethod()
    {
        // 实现方法
    }

    public int MyProperty { get; set; }

    public event EventHandler MyEvent;
}

public void MyFunction()
{
    IMyInterface myInterface = new MyClass();
    myInterface.MyMethod();
    myInterface.MyProperty = 10;
    myInterface.MyEvent += MyEventHandler;
}

private void MyEventHandler(object sender, EventArgs e)
{
    // 事件处理程序
}

public interface IMyInterface
{
    void MyMethod();
}

public class MyClass1 : IMyInterface
{
    public void MyMethod()
    {
        Console.WriteLine("MyClass1.MyMethod()");
    }
}

public class MyClass2 : IMyInterface
{
    public void MyMethod()
    {
        Console.WriteLine("MyClass2.MyMethod()");
    }
}

public void MyFunction(IMyInterface myInterface)
{
    myInterface.MyMethod();
}

public void Main()
{
    MyFunction(new MyClass1());
    MyFunction(new MyClass2());
}

MyClass1.MyMethod()
MyClass2.MyMethod()
