我正在使用 C#、.NET 3.5。我有以下代码
string.Compare("KHA","KTB",true)
它返回值 1。这意味着 KHA > KTB 按字母顺序排列。我希望它返回值-1。
谁能帮我解决这个问题？
是的，你们都是对的。这是因为文化。我添加 CultureInfo.InvariantCulture 并解决了。谢谢大家！

srig.Compare返回排序顺序中的相对位置。由于'H'出现在'T'之前，这就是你得到的原因1
它应该返回-1，查看图片
您的编译器一定有问题，它应该返回-1并且您对它的理解string.Compare是正确的。
您可以尝试使用CultureInfo.InvariantCulture：
int value = string.Compare("KHA", "KTB", true,CultureInfo.InvariantCulture);

The call string.Compare("KHA","KTB",true) should return -1 as expected. It does when I test it.
If you get any other result, you either are using other strings, or you have a default culture where 'T' is actually considered to come before 'H'.
For the latter case, you can specify a culture info in the call:
string.Compare("KHA", "KHB", true, CultureInfo.InvariantCulture)

If you are really getting 1 against string.Compare("KHA","KTB",true) then your system's current culture must be making an effect. Check the documentation of String.Compare. Also check the best practices of comparing a string here.
