Winform/Program以及如何将数组中的类1、类2、类3、类4写入链接标签？

Question

所以我的程序是这样工作的：使用winforms，用户输入ID号，使用一个数组，根据正确的ID号，将学生信息和课程表输出在消息框中！

我的问题是如何获取消息框/数组中的 4 个类并将它们写入表单 2 中的链接标签文本？？？

我的 Getschedule 类包含该数组，如下所示

： {

public class GetSchedule
{
    IDnumber[] IDnumbers = new IDnumber[3];

    public string GetDataFromNumber(string ID)
    {
        foreach (IDnumber IDCandidateMatch in IDnumbers)
        {

            if (IDCandidateMatch.ID == ID)
            {
                StringBuilder myData = new StringBuilder();
                myData.AppendLine(IDCandidateMatch.Name);
                myData.AppendLine(": ");
                myData.AppendLine(IDCandidateMatch.ID);
                myData.AppendLine(IDCandidateMatch.year);
                myData.AppendLine(IDCandidateMatch.class1);
                myData.AppendLine(IDCandidateMatch.class2);
                myData.AppendLine(IDCandidateMatch.class3);
                myData.AppendLine(IDCandidateMatch.class4);
                //return myData;
                return myData.ToString();
            }
        }
        return "";
    }

    public GetSchedule()
    {
        IDnumbers[0] = new IDnumber() { Name = "Joshua Banks", ID = "900456317", year = "Senior", class1 = "TEET 4090", class2 = "TEET 3020", class3 = "TEET 3090", class4 = "TEET 4290" };
        IDnumbers[1] = new IDnumber() { Name = "Sean Ward", ID = "900456318", year = "Junior", class1 = "ENGNR 4090", class2 = "ENGNR 3020", class3 = "ENGNR 3090", class4 = "ENGNR 4290" };
        IDnumbers[2] = new IDnumber() { Name = "Terrell Johnson", ID = "900456319", year = "Sophomore", class1 = "BUS 4090", class2 = "BUS 3020", class3 = "BUS 3090", class4 = "BUS 4290" };

    }
    public class IDnumber
    {
        public string Name { get; set; }
        public string ID { get; set; }
        public string year { get; set; }
        public string class1 { get; set; }
        public string class2 { get; set; }
        public string class3 { get; set; }
        public string class4 { get; set; }


       public static void ProcessNumber(IDnumber myNum)
            {
                StringBuilder myData = new StringBuilder();
                myData.AppendLine(myNum.Name);   
                myData.AppendLine(": ");
                myData.AppendLine(myNum.ID);
                myData.AppendLine(myNum.year);
                myData.AppendLine(myNum.class1);
                myData.AppendLine(myNum.class2);
                myData.AppendLine(myNum.class3);
                myData.AppendLine(myNum.class4);  
                MessageBox.Show(myData.ToString());
            }




    }

}

}

我的表单 2 将包含链接标签，如下所示：

public class YOURCLASSSCHEDULE : System.Windows.Forms.Form { 公共System.Windows.Forms.LinkLabel linkLabel1; 公共System.Windows.Forms.LinkLabel linkLabel2; 公共System.Windows.Forms.LinkLabel linkLabel3; 公共System.Windows.Forms.LinkLabel linkLabel4; 私有按钮button1；

    public System.ComponentModel.Container components = null;

    public YOURCLASSSCHEDULE()
    {

        //
        InitializeComponent();

        // TODO: Add any constructor code after InitializeComponent call

    }

    /// Clean up any resources being used.
    protected override void Dispose(bool disposing)
    {
        if (disposing)
        {
            if (components != null)
            {
                components.Dispose();
            }
        }
        base.Dispose(disposing);
    }

Answer 1

将 4 个类移至静态对象或业务层。使用业务层跨表单访问数据。

例如，使用它：

YourBusinessLayer.ScheduleManager manager = new ScheduleManager();

ScheduleManager.Add(new Schedule("Name", "ID", "Class", "Timings"); //Add schedules
List<Schedule> listOfAllSchedules= manager.GetSchedules(); //Get Schedules

manager.Schedule[0].ID
manager.Schedule[0].Name
manager.Schedule[0].Class
//....

然后，在任何表单中访问（编辑/更新）您的日程管理器。

顺便说一句，正如站点注释一样，类不应该（读：不能）是 GetSchedule；相反，一个类可能包含一个名为 GetSchedule() 的方法（读取：操作）。
