推荐答案

创建实例并在启动表单承包商中显示您的登录表单.如果结果不成功，请退出应用程序，或者将其放入循环中，让用户尝试3次.我给你写一个简单的书，你可以自己写另一个书.

Create instance and show your Login Form in your start up Form contractor. If the result wasn''t successful so exit the Application or you can put it in a loop for let user to try 3 times. I write you simple one, you can write another yourself.

static class Program
    {
        [STAThread]
        static void Main()
        {
            System.Windows.Forms.Application.Run(new Form1());
        }
    }

public partial class Form1: Form
{
    public Form1()
    {
         loginForm _form = new loginForm();

         if (_form.ShowDialog() == DialogResult.Cancel)
             Application.Exit()

         InitializeComponent();
    }
}

您可以在Usercontrol中创建一个委托，并在用户成功登录系统后调用该委托.

您需要以将要关闭当前表单的主表单创建函数.您先前创建的委托将指向此函数.

希望我回答了你的问题，

要进行裁判检查，请执行以下操作:从用户控件中调用父表单函数 [ ^ ]

Hi,

You can create one delegate in the Usercontrol and Invoke the delegate when user is successfully login into the system.

You need to create function in main form that will close the current form. And the delegate that you have previously created will pointing to this function.
