    {

            if (RadioMale.Checked == true)
            {

            + "\n__________________________________________________";

        Form frm2 = new Form2();
        frm2.Show();
    }

我的尝试：



i尝试了表单实例函数，但它没有工作它只是保持这个表单2并且不允许打开新表单！使用这些代码：

What I have tried:

i tried form instance function but its not working its just hold this form 2 and will not allow to open new one! with these code:

public static Form2 Instance
   {
       get
       {
           if (_form2 == null)
           {
               _form2 = new Form2();
           }
           return _form2;

       }
   }

推荐答案

我建​​议你看一下应用程序.OpenForms-Collection如果Form2已经打开。

I would suggest you look inside the Application.OpenForms-Collection if the Form2 is allready opened.
