When some or all components in a chain satisfy a given condition, these operators return a Boolean result, i.e. True or False.
Examples:
| Operator | Particulars | C# Query Expression Syntax | VB Query Expression Syntax |
| Any | It helps determine that whether elements of a succession satisfy specified criteria by searching it. | Not Applicable | Aggregate … In … Into Any() |
| All | If all items of a sequence meet a predicated criterion, the value 'True' is returned. | Not Applicable | Aggregate … In … Into All(…) |
| Contains | A' True' value is produced if a certain value is found in a sequence; if the sequence does not include that specific element, a 'false' value is returned. | Not Applicable | Not Applicable |
