从另一张FORM中取回隐藏的FORM

Question

我有两种形式Form1,并Form2

我打开Form2从Form1上button_Click

Form2 obj2 = new Form2();
this.Visible = false;
obj2.Show();

然后我想回到Form1可见的(处置Form2)在我离开的控件的相同状态.....

Answer 1

你Form2什么都不知道Form1.它需要一个引用(你可以通过添加一个Form类型属性Form2并Form1在构造后分配给它):

//In Form2
public Form RefToForm1 { get; set;}

//In Form1
Form2 obj2 = new Form2();
obj2.RefToForm1 = this;
this.Visible = false;
obj2.Show();

//In Form2, where you need to show Form1:
this.RefToForm1.Show();
