The FilterCondition.Like operator determines whether a specific character string matches a specified pattern or not.

The following wildcard characters are supported:

  • % matches a string of zero or more characters. For instance:

    CriteriaOperator.Parse("Name like 'Jo%'") - returns all the objects whose Name begins with 'Jo'.

    CriteriaOperator.Parse("Name like '%car%'") - returns all the objects whose Name contains the 'car' substring.

  • _ matches a single character. For instance:

    CriteriaOperator.Parse("Name like 'car_'") - returns all the objects whose Names consist of four characters and begin with 'car'.

  • [ ] identifies a single character within the specified range ([a-c]) or set ([abc]). For instance:

    CriteriaOperator.Parse("Name like '[A-C]%'") - returns all the objects whose Name begins with 'A', 'B' or 'C'.

  • [^] excludes a single character not within the specified range ([^a-c]) or set ([^abc]). For instance:

    CriteriaOperator.Parse("Name like 're[^de]%'") - returns all the objects whose Name begins with 're', and where the following letter is not 'd' or 'e'.
