The StringComparison enumeration is used to specify whether a string comparison should use the current culture or the invariant culture, word or ordinal sort rules, and be case-sensitive or case-insensitive.重要 When you call a string comparison method such as String.Compare, String.Equals, or ...
(StringComparison.CurrentCulture and StringComparison.CurrentCultureIgnoreCase) or the invariant culture (StringComparison.InvariantCulture and StringComparison.InvariantCultureIgnoreCase), or it can consist of a character-by-character comparison of code points (StringComparison.Ordinal or StringComparison....
The comparisonType parameter specifies to search for the value parameter using the current or invariant culture, using a case-sensitive or case-insensitive search, and using word or ordinal comparison rules. Examples The following code example demonstrates three overloads of the Last...
