        private void button4_Click(object sender, EventArgs e)
        {
            F1 f1 = new F1();
            f1.Show();
            Button btn = f1.Controls["button1"] as Button;
            btn.Enabled = false;
        }

查找form1的控件
((PictureBox)f1.Controls["pictureBox1"]).ImageLocation = pathPic + "\\" + path;

[abutwang]

Form f1 = new Form();
private void button4_Click(object sender, EventArgs e)
{
f1.Show();
Control[] controls=f1.Controls.Find("button1",true);

if(controls.length>0)
{
Button btn = controls[0] as Button;
btn.Enabled = true;
}
}
