类成员如何获取类对象实例
class Company
{
List<Department> deptList;

private List<Department> DeptList
{
get { return deptList; }
set { deptList = value; }
}

}
class Department
{
private Company parent;

internal Company Parent
{
get
{
//这里怎么写才能获得当前Company的对象实例？？？
}
//set { parent = value; }
}
}
[解决办法]
class Department
{
private Company _parent;

public Department(Company parent)
{
this._parent = parent;
}

internal Company Parent
{
get
{ return this._parent;}
//set { _parent = value; }
}
}

在Company类中，给List<Department>赋值时使用带参的构造函数来New Department(this)
如果Department的无参构造是必需的，使用Department.Parent时就判断下是否为null

真要较真的话就做成静态的

 class Company
    {
     private static Company _Company;
      public static Company Company
      {
         get;
      }

   
        List<Department> deptList;

        private List<Department> DeptList
        {
            get { return deptList; }
            set { deptList = value; }
        } 
 

    }
