One more Quiz about String Interning

在Whidbey上运行如下的两个测试并解释结果：

Test 1:

using System;

class Test

{

    static public void Main()

    {

        Console.WriteLine(object.ReferenceEquals(string.Empty, string.Intern(string.Empty)));

    }

}

Test 2:

using System;

class Test

{

    static public void Main()

    {

        Console.WriteLine(object.ReferenceEquals(string.Empty, string.Intern(string.Empty)));

        Console.WriteLine(object.ReferenceEquals(string.Empty, string.Intern("")));

    }

}
