Question

class Form1: Form
{
    public void showNewDialog()
      {
         Form2 = new Form2();
         diagForm.showDialog(this);
         diagForm.Dispose();
      }
}

在上述法典中,<代码>diagForm的所有人财产被设定为NUL。如何确定 Owner property to Form1 instance?

Answer 1

You can set the owner this way :

class Form1: Form
{
.
.
.
    public void showNewDialog()
    {
        Form2 diagForm = new Form2(){ Owner = this };
        diagForm .showDialog();
        diagForm .Dispose();
    }
}

If you check the Owner in the diagForm constructor it will be null, but if you check it in the onLoad event it will be form1

Answer 2

f.Owner = this;

它只是公有财产,因此你可以直截了当。

Answer 3

If you check Owner property in Shown event in Form2, you ll find that it s set to Form1.
