·        Use overloads that explicitly specify the stringcomparison rules for string operations. Typically, this involves calling amethod overload that has a parameter of type.

对字符串操作时使用明确地指定字符串比较规则那些重载函数。

通常，这意味这调用有一个参数类型为StringComparison的重载函数。

·        Use StringComparison.Ordinalor StringComparison.OrdinalIgnoreCase forcomparisons as your safe default for culture-agnostic string matching.

通过StringComparison明确指明是否区分大小（而不是使用默认的，默认的规则在各个类里可能并不一致）

·        Use comparisons with StringComparison.Ordinalor StringComparison.OrdinalIgnoreCase forbetter performance.

·        Use string operations that are based on StringComparison.CurrentCulture when you displayoutput to the user.

如果相应的字符串会显示给用户，那么使用基于StringComparison.CurrentCulture的字符串操作

·        Use the non-linguistic StringComparison.Ordinal or StringComparison.OrdinalIgnoreCase values insteadof string operations based onwhen the comparison is linguistically irrelevant (symbolic, for example).

如果比较是语言学无关的，使用StringComparison.Ordinal or StringComparison.OrdinalIgnoreCase (效率会更高？)，而不是

·        Use the method instead of the method when you normalize strings for comparison.

推荐使用 而不是

·        Use an overload of the method to test whether two strings are equal.

使用string.equals的重载方法测试两个string是否一致。

·        Use and to sort strings, not to check for equality.

将Compare和CompareTo用于对字符串进行排序，而非用于一致性检查

Avoid the following practices when you use strings:

·        Do not use overloads that do not explicitly orimplicitly specify the string comparison rules for string operations.

不要使用那些没有或明或暗指定比较规则的字符串操作函数

·        Do not use string operations based on StringComparison.InvariantCulture in most cases.One of the few exceptions is when you are persisting linguistically meaningfulbut culturally agnostic data.

//z 2012-2-7 16:50:57 PM IS2120@CSDN

在大多数时候都不要使用基于StringComparison.InvariantCulture的函数。

·        Do not use an overload of the or method and test for a return value of zero to determine whether two strings areequal.

不得使用String.Compare或是CompareTo通过测试返回值是否为0来判断两个字符串是否相等。
