Implements common functionality for queries against a conceptual model using both LINQ to Entities and ObjectQuery<T>.
Assembly: System.Data.Entity (in System.Data.Entity.dll)
Thetype exposes the following members.
|CommandText||Returns the command text for the query.|
|Context||Gets the object context associated with this object query.|
|EnablePlanCaching||Gets or sets a value that indicates whether the query plan should be cached.|
|MergeOption||Gets or sets how objects returned from a query are added to the object context.|
|Parameters||Gets the parameter collection for this object query.|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Execute||Executes the untyped object query with the specified merge option.|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetResultType||Returns information about the result type of the query.|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|ToTraceString||Returns the commands to execute against the data source.|
|AsParallel||Enables parallelization of a query. (Defined by ParallelEnumerable.)|
|AsQueryable||Converts an IEnumerable to an IQueryable. (Defined by Queryable.)|
|Cast<TResult>()||Overloaded. Converts the elements of an IQueryable to the specified type. (Defined by Queryable.)|
|Cast<TResult>()||Overloaded. Converts the elements of an IEnumerable to the specified type. (Defined by Enumerable.)|
|OfType<TResult>()||Overloaded. Filters the elements of an IQueryable based on a specified type. (Defined by Queryable.)|
|OfType<TResult>()||Overloaded. Filters the elements of an IEnumerable based on a specified type. (Defined by Enumerable.)|
|IEnumerable.GetEnumerator||Returns an enumerator that iterates through a collection.|
|IListSource.ContainsListCollection||Gets a value that indicates whether the collection returned by the query contains collection objects.|
|IListSource.GetList||Returns the collection as an IList used for data binding.|
|IQueryable.ElementType||Gets the result element type for this query instance.|
|IQueryable.Expression||Gets the expression describing this query.|
|IQueryable.Provider||Gets the LINQ IQueryProvider associated with this query instance.|
is the base class for queries against a conceptual model. is provided to ensure that LINQ to Entities queries have the same functionality as queries executed using ObjectQuery<T>. You must use ObjectQuery<T> with a specified type to query a conceptual model. For more information, see Object Queries (Entity Framework).
