从另一个 FORM 中取回隐藏的 FORM

我有两种形式Form1 and Form2

我正在打开Form2 from Form1 on button_Click

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

然后我想回来Form1可见的（关于处置Form2)处于与我离开时相同的控件状态......

Your Form2什么都不知道Form1。它将需要对其的引用（您可以通过添加Form键入属性Form2并分配Form1施工后）：

//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();
