推荐答案

这是可能的，但前提是您的读者是Employee类的后代或实现相同的接口:
1)

It''s possible, but only when your reader is either descendant of Employee class or realizes the same interface:
1)

public class Employee
{
...
}

public class Reader: Employee
{
...
}

2)

2)

interface IEmployee
{
...
}

public class Employee: IEmployee
{

...
}

public class Reader: IEmployee
{
...
}
