在 C# 中將一個類對象添加到另一個類中

Question

我有兩個班級，一個叫學位，另一個叫Uprogram。 我想在 UProgram 中添加一個變量來保存一個 degree 對象。 我該怎么做？

class UProgram
    {
       //private member variables for UProgram
        private string programName;
        private string departmentName; 


    //public properties for UProgram
    public string ProgramName
    {
        get { return programName; }
        set { programName = value; }
    }
    public string DepartmentName
    {
        get { return departmentName; }
        set { departmentName = value; }
    }  
}


class Degree
    {
        //private member variables for Degree
        private string degreeType;
        private string degreeName;

   //public properties for Degree
    public string DegreeType
    {
        get { return degreeType; }
        set { degreeType = value; }
    }
    public string DegreeName
    {
        get { return degreeName; }
        set { degreeName = value; }
    }
}

Answer 1

以與添加字符串屬性相同的方式：

class UProgram
{
    //private member variables for UProgram
    private string programName;
    private string departmentName;
    private Degree degree;

    //public properties for UProgram
    public string ProgramName
    {
        get { return programName; }
        set { programName = value; }
    }
    public string DepartmentName
    {
        get { return departmentName; }
        set { departmentName = value; }
    }

    public Degree Degree
    {
        get { return degree; }
        set { degree = value; }
    }
}

現在你可以提供一個合適的構造函數來傳遞度對象或簡單地使用屬性：

UProgram prog = new UProgram();
Degree degree = new Degree { DegreeName = "Foo", DegreeType = "type" };
prog.Degree = degree;

Answer 2

做一個類型的財產Degree在UProgram

Answer 3

class UProgram
{
   //private member variables for UProgram
    private string programName;
    private string departmentName; 
    private Degree __degree;

//public properties for UProgram
public string ProgramName
{
    get { return programName; }
    set { programName = value; }
}
public string DepartmentName
{
    get { return departmentName; }
    set { departmentName = value; }
}  
public Degree UProgDegree
{
    get{return __degree;}
    set {__degree = value;}
}

}
