Question

我想将一个非静态类的对象存储在另一个非静态类的静态字段中，并通过第二个类的属性访问它们。请帮帮我。

class Student
{
    private string fullname;
    private string course;
    private string subject;
    public Student(string fullname, string course)
    {
        this.fullname = fullname;
        this.course = course;            
    }

    public Student(string fullname, string course, string subject)
    {
        this.fullname = fullname;
        this.course = course;
        this.subject = subject;            
    }

    public string FullName { get { return fullname; } set { fullname = value; }}        
        public string Course { get { return course; } set { course = value; }}
        public string Subject { get { return subject; } set { subject = value;}}
}

class StudentData
{
    private static Student bscStudent;
    private static Student mscStudent;        

    public StudentData()
    {
    }

    private static void GetStudentData()
    {
        Student student = new Student(" Isoboye Vincent", "IT");
        Student student2 = new Student(" Doris Atuzie", "IT", "C#");            

        bscStudent= student;
        mscStudent= student2;                       
    }

    public static Student BscStudent { get { return bscStudent; } set { bscStudent = value; } }
    public static Student MscStudent { get { return mscStudent; } set { mscStudent = value; } }        
}

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("List of students");
        Console.WriteLine(StudentData.BscStudent);
        Console.WriteLine(StudentData.MscStudent);            

        Console.ReadKey();
    }
}

// Output: 
//List of students

现在我了解了问题所在，因此我提出了以下解决方案：

private static Student _BscStudent = null;
public static Student BscStudent { 
    get {
        if (_BscStudent == null) {
            _BscStudent = new Student(" Isoboye Vincent", "IT");
        } 
        return _BscStudent; 
    } 
    set { _BscStudent = value; } 
}

private static Student _MscStudent = null;
public static Student MscStudent { 
    get { 
        if (_MscStudent == null) {
            _MscStudent = new Student(" Doris Atuzie", "IT", "C#");
        } 
        return _MscStudent; 
    } 
    set { 
        _MscStudent = value; 
    } 
}

我很长时间没有使用C＃，所以我可能不记得一种更简单的方法。无论如何，从此解决方案开始，如果发现更好的方法，也许以后再重构该代码。

添加一个类的对象并存储在另一个类的静态字段中，并通过第二个类的属性访问它们
