先将form3的label1的modifier属性为public ,一个button1,
private void button1_Click(object sender, EventArgs e)
{
//显示form1
Form1 f1 = new Form1(this);
f1.Show();
f1.Hide();
}
private Form３ f3;
public Form１(Form３ parent)
{
InitializeComponent();
f3 = parent;
f3.label1.Text = textBox1.Text;
}
public static Form3 f1 = null;
public Form3()
{
InitializeComponent();
f1 = this;
}
private void button1_Click(object sender, EventArgs e)
{
Form1 f2 = new Form1();
f2.Show();
f2.Hide();
}
public Form1()
{
InitializeComponent();
Form3.f1.label1.Text = textBox1.Text;
}
