推荐答案

int count = 0;
for (int i = 0; i < Application.OpenForms.Count; i++)
{
    if (Application.OpenForms[i].Visible == true)
        count++;
}
label1.Text = count.ToString(); // Active Forms value :)

private void button1_Click(object sender, EventArgs e)
        {
            int count = Application.OpenForms.Count;
            MessageBox.Show("" + count);
        }

感谢UR编码:)
