C# 字符串 : why string a == b operator gives different answer than a. CompareTo(b) == 0？

Question

我稍微弄乱了 C#，发现一段代码给出了非常不舒服的结果:

static void Main(string[] args)
    {
        string a = "string", b = "string\0";
        bool b1 = a == b;
        bool b2 = (a.CompareTo(b) > 0);
        bool b3 = (a.CompareTo(b) < 0);
        bool b4 = (a.CompareTo(b) == 0);
        Console.WriteLine(a);
        Console.WriteLine(b);
        Console.WriteLine("{0} {1} {2} {3}", b1, b2, b3, b4);
    }

输出:

string
string
False False False True

预期输出(关于):

string
string
True False False True

Answer 1

CompareTo 的结果并不意味着相等，它与排序顺序有关。我不确定出于排序目的而忽略空字符是否太令人惊讶。

根据 the documentation :

Character sets include ignorable characters. The CompareTo(String) method does not consider such characters when it performs a culture-sensitive comparison.
