CompositePredicateDescription Class

Represents the conditional And/Or of two dynamically built predicate clauses.

Syntax

Visual Basic
C#

'Declaration
 
Public Class CompositePredicateDescription

'Usage
 
Dim instance As CompositePredicateDescription

public class CompositePredicateDescription

Remarks

A CompositePredicateDescription is returned when using the DynamicQueryExtensions.And or DynamicQueryExtensions.Or methods, or by similar methods on the PredicateBuilder. You can build a filtered query using PredicateBuilder.FilterQuery or create a lambda expression from the predicate using ToLambdaExpression.

Example

public void PredicateBuilderMake() {
  var mgr = new DomainModelEntityManager();

  var expr1 = PredicateBuilder.Make(typeof(Product), "UnitPrice", FilterOperator.IsLessThanOrEqualTo, 10);
  var expr2 = PredicateBuilder.Make(typeof(Product), "Discontinued", FilterOperator.IsEqualTo, false);

  var results = mgr.Products.Where(expr1.And(expr2)).ToList();
}
