Parameters

expression

An expression tree that represents a LINQ query.

Return Value

Type: System.Linq.IQueryable
An IQueryable that can evaluate the query represented by the specified expression tree.

NoteNote

The Expression property of the returned IQueryable object is equal to expression.

The CreateQuery method is used to create new IQueryable objects, given an expression tree. The query that is represented by the returned object is associated with a specific LINQ provider.

Several of the standard query operator methods defined in Queryable, such as OfType<TResult> and Cast<TResult>, call this method. They pass it a MethodCallExpression that represents a LINQ query.
