    Performs a 'like' comparison between the specified string and pattern.

    Declaration
    public static bool Like(this string str, string pattern, bool caseSensitive = true)
    Parameters
    Type Name Description
    String str

    The string to compare against the pattern.
    String pattern

    The pattern to compare against.
    Boolean caseSensitive

    If set to true performs a case sensitive comparison.
    Returns
    Type Description
    Boolean

    true if the string matches the pattern, false otherwise.
    Remarks

    ? and are allowed where ? matches a single character and matches zero or more characters, such that ?bc* matches abcde and bbc, but does not match bcd.

    This extension method can be used in LINQ queries against the IQueryable returned from All(String). If used outside of a query context, it will use a Regex to perform the comparison using the same rules.
