推荐答案

这并不难：但你究竟是怎么做的，取决于你如何在第一时间处理登录。



就个人而言，我会首先打开主表格，然后在加载活动中打开登录表格：

It's not to difficult: but exactly how you do this depends on how you handle the login on the first place.

Personally, I would bring the main form up first, and open the login form in the Load event:

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;

你能告诉我们你的代码片段吗？ />
OriginalGriff是对的，使用属性登录表单如果你想创建一个属性的类，它将保存你想要传递的值

can you show us your code snippets?
OriginalGriff was right,using property to the log in form ur If you want create a class for property that will hold the value you want to pass

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;

你好。当您决定创建应用程序时，请考虑以下事项：

1 - 您需要什么数据？

2 - 创建一个包含您请求数据的类：

在类中，您可以定义用于处理该类的属性，例如：

Hi there. when you are deciding for creating a application consider followings:
1-what data you need?
2-create a class that has your requested data:
In a class you can define property for working with that class such as this:

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;
}
