Is there an equivalent to the C# String.Contains function?
For, example, in SQL I can do the following:
ToLower(nameFile) like "%(restricted)%"
The "like" expression is SQL only. You can use it inside an aggregate or a SQL tool.
Use the function "Index" to search for a string inside the other. If the result is greater than or equal to 0, the string contains the searched string.
Index(ToLower(nameFile), "(restricted)", startIndex:, searchIndex:, ignoreCase:) >= 0
