Question

//When clicked on a button on this form this class will show a form to renew the license

private void button1_Click(object sender, EventArgs e)
{
    Notif f = new Notif();
    f.Show();
    int b = 

    //how to get the value from Valid class
}

//This is the class of a form which will display a renew button to renew the license

private void button1_Click(object sender, EventArgs e)
{
    int d = DateTime.Now.Day;
    this.Close();

    //how to pass this date to form1 class...??      

}

//This is the class to capture the value of the day sent from the renew button of the above class

public static  class Valid
{
    public int day { get; set; }

}

我正在寻找问题的解决方案，即，如果单击了更新按钮，如何在Form1类中获取当天的值。？

您可以阅读每个课程中提到的注释，您将理解问题

Answer 1

因此，您想将int d发送到Valid类，然后将其发送到int b = ...？

public static class Valid
{
     public static int _day; /* if you have setters and getters 
                    with day and you dont want a stack overflow you need _day*/
     public static int day {get{return _day; } set{_day=value;}}
}

这是表单的类别，该表单将显示用于更新许可证的续订按钮

public int alternative_d;
private void button1_Click(object sender, EventArgs e)
{
     int d = DateTime.Now.Day;
     Valid.day=d; 
     alternative_d=d;
     this.Close();
     //how to pass this date to form1 class...??      
}

当单击此表单上的按钮时，该课程将显示一个续订许可证的表单

private void button1_Click(object sender, EventArgs e)
{
    Notif f = new Notif();
    f.ShowDialog(); /*<-- use show dialog, your code resumes at next line when f is closed*/
    int b = Valid.day;//how to get the value from Valid class
    int b= f.alternative_d; //either one or the other; no extra class needed
}

如何在静态类的帮助下在类之间传递值？
