Remarks
.gif "Note") Note: |
|---|
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.
