推荐答案

您应该研究使用IIdentity和IPrincipal接口.我写了一篇文章，向您展示如何创建自己的凭据对象

WinForms-通过AspNetDb使用自定义主体 [
然后，您可以使用以下几行代码来检查用户是否输入了正确的用户名\ pwd

You should look into using the IIdentity and IPrincipal interfaces. I wrote an article that shows you how you can create your own credential objects

WinForms - Using a custom principal with AspNetDb[^]

The article shows how to create ''AspNetDb'' credentials, but you can customise the AspNetDbIdentity ctor to retrieve username and password from whatever database you like. You''d also need to change IIdentity.IsAuthenticated to tell when the user has input correct credentials

You could then use code along the following lines to check that user has input the correct username \ pwd

if (Thread.CurrentPrincipal.Identity.IsAuthenticated)
{
    // show some form when user is authenticated
}

嗨 我认为第二个比第一个好，因为未经授权，未经登录就无法查看下一个屏幕.

您可以执行以下操作:
假设您的登录表单名称为frmLogin，主表单为frmHome

Hi I think the second is better than first, because unauthorized would not able to see the next screen without doing logged in.

you can do as follows:
Suppose your login form name is frmLogin and main form is frmHome

btnLogin_Click(..)
{
 //code to be written here for login authentication...
 if(success)
 {
   frmHome home = new frmHome();
   home.show();
   this.close();
 } 
}
