推荐答案

您可以使用委托.

您将在您的form1中添加一个委托签名:

You can use delegates.

you will add a delegate signature to your form1:

public delegate void Passchangeobject(MyObject obj);

然后在您的事件下更改对象时，您将使用将添加到form2中的函数来调用委托.

and then when your object is changed under your event, you call your delegate with the function that you will add in your form2

Passchangeobject delchange = new Passchangeobject(f2.GetChanges);
//f2 is your form2
delchange(ms);

并且应该将GetChanges函数添加到form2

And you should add GetChanges function to your form2

 public void GetChanges(MyObject ms2)
{

            textBox1.Text = ms2.GetName();
            // you do here whatever you want

}

它应该可以工作

it should work
