pattern string: The regular expression pattern to match.
options RegexOptions: Optional RegexOptions to modify the search behavior. Default is IgnoreCase.

Searches the specified input string for the first occurrence of a regular expression pattern.

public static Match Match(this string? value, string pattern, RegexOptions options = RegexOptions.None)

value string: The input string to search. If null, returns an empty Match(string?, string, RegexOptions).
pattern string: The regular expression pattern to match.
options RegexOptions: Optional RegexOptions to modify the search behavior. Default is None.

Match: A Match(string?, string, RegexOptions) object containing information about the first match found in value. If value is null, returns an empty match.

Replaces all occurrences of a specified regular expression pattern in the input string with a replacement string.

public static string? ReplacePattern(this string? value, string pattern, string newValue, RegexOptions options = RegexOptions.None)

value string: The input string to modify. If null, returns an empty string.
pattern string: The regular expression pattern to match.
newValue string: The replacement string. If null, it is treated as an empty string.
options RegexOptions: Optional RegexOptions to modify the search behavior. Default is None.
