今天继续看MSDN, 不经意间却发现了下面这段代码，测试了下，没想到微软的工程师也有不小心的时候

字符串对象也有一个 CompareTo() 方法，它根据一个字符串小于 (<)、等于 (==) 还是大于 (>) 另一个字符串而返回一个整数值。比较字符串时使用 Unicode 值，并且小写字母的值小于大写字母的值。有关比较字符串的规则的更多信息，请参见。

C#	复制代码
// Enter different values for string1 and string2 to // experiement with behavior of CompareTo string string1 = "ABC"; string string2 = "abc"; int result = string1.CompareTo(string2); if (result > 0) { System.Console.WriteLine("{0} is greater than {1}", string1, string2); } else if (result == 0) { System.Console.WriteLine("{0} is equal to {1}", string1, string2); } else if (result < 0) { System.Console.WriteLine("{0} is less than {1}", string1, string2); } // Outputs: ABC is less than abc 是这回事吗？

复制代码

// Enter different values for string1 and string2 to
// experiement with behavior of CompareTo
string string1 = "ABC";
string string2 = "abc";

int result = string1.CompareTo(string2);

if (result > 0)
{
    System.Console.WriteLine("{0} is greater than {1}", string1, string2);
}
else if (result == 0)
{
    System.Console.WriteLine("{0} is equal to {1}", string1, string2);
}
else if (result < 0)
{
    System.Console.WriteLine("{0} is less than {1}", string1, string2);
}
// Outputs: ABC is less than abc 是这回事吗？
