	MainForm (按钮名btnMethod1)

	
	publicvoid myMethod1() { this.Text ="方法一"; }
	privatevoid btnMethod1_Click(object sender, EventArgs e)
	{
	ChildForm child1 =new ChildForm();
	child1.Owner =this; // 必须设置
	child1.ShowDialog();
	}

	

	ChildForm (按钮名btnMethod1)

	privatevoid btnMethod1_Click(object sender, EventArgs e)
	{
	MainForm main1 = (MainForm)this.Owner;
	main1.myMethod1();
	main1.textBox1.Text =this.textBox1.Text;
	}

	

	// 方法二：自身传递法
	// ************************************************************************
	// MainForm (按钮名btnMethod2)

	publicvoid myMethod2() { this.Text ="方法二"; }
	privatevoid btnMethod2_Click(object sender, EventArgs e)
	{
	ChildForm child2 =new ChildForm(this);
	child2.ShowDialog(this);
	}

	

	// ChildForm (按钮名btnMethod2)

	
	private MainForm main2;
	public ChildForm(MainForm mainform) // 重载ChildForm
	{
	InitializeComponent();
	main2 = mainform;
	}
	privatevoid btnMethod2_Click(object sender, EventArgs e)
	{
	main2.myMethod2();
	main2.textBox2.Text =this.textBox2.Text;
	}

	

	

	// 方法三：属性法
	// ************************************************************************
	// MainForm (按钮名btnMethod3)

	
	publicvoid myMethod3() { this.Text ="方法三"; }
	privatevoid btnMethod3_Click(object sender, EventArgs e)
	{
	ChildForm child3 =new ChildForm();
	child3.MAIN3 =this;
	child3.ShowDialog();
	}

	

	// ChildForm (按钮名btnMethod3)

	
	private MainForm main3;
	public MainForm MAIN3
	{
	get { return main3; }
	set { main3 = value; }
	}
	privatevoid btnMethod3_Click(object sender, EventArgs e)
	{
	main3.myMethod3();
	main3.textBox3.Text =this.textBox3.Text;
	}

	

	

	// 方法四：委托法
	// ************************************************************************

	
	// MainForm (按钮名btnMethod4)
	publicdelegatevoid myDelegate4(); // 声明一个委托

	privatevoid btnMethod4_Click(object sender, EventArgs e)
	{
	ChildForm child4 =new ChildForm();
	child4.myDelegate4Test +=new myDelegate4(myMethod4);
	child4.ShowDialog();
	}

	

	// ChildForm (按钮名btnMethod4)

	publicevent MainForm.myDelegate4 myDelegate4Test; // 声明事件
	privatevoid btnMethod4_Click(object sender, EventArgs e)
	{
	myDelegate4Test();
	}
