c#里可以自定义数据类型，具体怎么做呢

Question

class Professor {private string title;private Department worksFor;}如果我想打印Professor 的attribute title和 worksFor，那么Department 类里面应该怎么写呢

Answer 1

首先你要有 Department 这个类
可以初始化
class Department{
private string a1;
private int b1;
.....
private void YourMethod()
{
///
}
}

在你的Professor 类里 调用worksFor.YourMethod() 方法就可以实现了

Answer 2

public static string userName= string.Empty;
public static string getUserName
{
get { return userName; }
}

public static string setUserName
{
set { userName = value; }
}
封装字段
