考虑这个代码:
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; }
}
显然，当将person1赋给person2并且person2的Name属性被更改时，person1的Name也将被更改.person1和person2具有相同的引用.
为什么当为person2 = null时，person1变量也不为空？
