C# | Char.GetUnicodeCategory(String, Int32) Method with Examples Last Updated : 17 Jan, 2023 Comments Improve Suggest changes Like Article Like Report This method is used to categorizes the character at the specified position in a specified string into a group identified by one of the UnicodeCategory values. Syntax: public static System.Globalization.UnicodeCategory GetUnicodeCategory (string s, int index); Parameters: s: It is the String.index: It is the character position in s. Return Value: This method returns a UnicodeCategory enumerated constant that identifies the group that contains the character at position index in s. Exceptions: ArgumentNullException: If the s is null.ArgumentOutOfRangeException: If the index is less than zero or greater than the last position in s.
