推荐答案

frmLogin log = new frmLogin();
if (log.ShowDialog() != DialogResult.OK)
   {
   Close();
   }

然后在登录表单中执行所有验证，然后单击确定或取消退出，具体取决于登录是否有效 - 如果不然，则上面的代码关闭应用程序。



所有你要做的就是在登录表单中添加一个属性，该表单返回登录用户名，并在主公司代码中访问它：

You then do all the validation in the login form and exit with OK or Cancel depending on if the logon works or not - if it doesn't, then the code above closes the application.

All you then have to do is add a property to the login form which returns the login user name, and access it in the main firm code:

Text = "User : " + log.UserName;

Public Class MyClass
{
public string myValue{get;set;}

}

登录表格：

Log in form:

If (textBox1.text==password and textBox2.Text==UserAccount)
{
  var cls=new myClass;//instantiate the class
  cls.myValue=textBox2.Text;//pass the value
  MainForm.ShowDialog();
}

然后是主表格

then in Main form

var cls=new myClass;
textBox3.Text=cls.myValue;

class Person
{
    public string UserName { get; set; }
    public string Password { get; set; }

    private Person()
    {
        Validate();
    }
    public Person()
    {

    }

    private void Validate()
    {
        //Here you must connect to some dataSource such as SQL server for correction of entry data
    }
}

3 - 现在你必须设计你的用户界面（表格）。

4-我想你创建一个表格两个TextBoxes和两个Button。在LogButton_Click中：

3-now you must design your UI(form).
4- I suppose you create a form that has two TextBoxes and two Button. In LogButton_Click:

public Form1()
{
    InitializeComponent();
}

private void LogInButton_Click(object sender, EventArgs e)
{
    Person person = new Person();
    person.UserName = UsernameTextBox.Text;
    person.Password = PasswordTextBox.Text;
}
