考虑以下代码:

public class Program
{
    private static void Main(string[] args)
    {
        var person1 = new Person { Name = "Test" };
        Console.WriteLine(person1.Name);

        Person person2 = person1;
        person2.Name = "Shahrooz";
        Console.WriteLine(person1.Name); //Output: Shahrooz
        person2 = null;
        Console.WriteLine(person1.Name); //Output: Shahrooz
    }
}

public class Person
{
    public string Name { get; set; }
}

很显然,当分配person1到person2与Name物业person2发生变化,Name中person1也将改变.person1并person2有相同的参考.

为什么何时person2 = null,person1变量也不会为空？
