恢复对象中包含的几个值 c#

Question

我在我的按钮中开始活动：

private void button1_Click(object sender, EventArgs e)
{
 _info.Event(value,data); // _info declared above for call from other class
 _info.Event(value2,data2);
}

我的表格：

public Form1()
{
 _info = new Info();
 _info.NewData += CustomEvent;
}

并用于显示：

private void CustomEvent(object sender, MyEvent e)
{
 textBox1.Text = (e.data).ToString();
 textBox2.Text = (e.data).ToString(); //only this value show in both textboxs
}

我的问题是：我尝试使用我的事件来恢复多个值，但我不知道如何分隔对象中的值以便在不同的文本框中显示它们？

这是一个关于如何使用 delegates:
的例子 当然，您可以更改委托中的参数。我选择了"string data"和"bool success"，但是你可以改变它们。

public class Foo
{
    public delegate void MyDataDelegate(string data, bool success); //create a delegate (=custom return/param type for event)
    public event MyDataDelegate OnMyEvent; //create event from the type of the early created delegate

    private void myMethod()
    {
        //do something 
        bool success = true;
        OnMyEvent?.Invoke("some data", success); //invoke event (use "?" to check if it is null). Pass the params
    }
}

public class MyClass
{
    Foo myFoo;

    public MyClass()
    {
        myFoo = new Foo();
        myFoo.OnMyEvent += OnMyEventtriggered; //subscribe to the event in the costructor of your class
    }

    private void OnMyEventtriggered(string data, bool success)
    {
        //do something
    }
}
