有什么方法可以使这个工作代码更简单吗?

 public partial class Form1 : Form
{
    private CodeDevice codeDevice;
    public Form1()
    {
        InitializeComponent();
        codeDevice = new CodeDevice();
        //subscribe to CodeDevice.ConnectionSuccessEvent and call Form1.SetupDeviceForConnectionSuccessSate when it fires
        codeDevice.ConnectionSuccessEvent += new EventHandler(SetupDeviceForConnectionSuccessState);
    }
    private void SetupDeviceForConnectionSuccessState(object sender, EventArgs args)
    {
        MessageBox.Show("It worked");
    }
    private void button1_Click(object sender, EventArgs e)
    {
        codeDevice.test();
    }
}
public class CodeDevice
{
    public event EventHandler ConnectionSuccessEvent = delegate { };
    public void ConnectionSuccess()
    {
        ConnectionSuccessEvent(this, new EventArgs());
    }
    public void test()
    {
        System.Threading.Thread.Sleep(1000);
        ConnectionSuccess();
    }
}

WinForm事件订阅到另一个类

如何订阅其他课程'c#中的事件?

WinForm事件在另一个类.net 2简化委托

如果你不认为你可以简化:

public event EventHandler ConnectionSuccessEvent = delegate { }

即使在c#3 +中你也只能做

public event EventHandler ConnectionSuccessEvent = () => { }

但是你可以简化

codeDevice.ConnectionSuccessEvent += new EventHandler(SetupDeviceForConnectionSuccessState);


codeDevice.ConnectionSuccessEvent += SetupDeviceForConnectionSuccessState;
