Assembly: System.Data.Services (in System.Data.Services.dll)
[AspNetCompatibilityRequirementsAttribute(RequirementsMode = AspNetCompatibilityRequirementsMode::Allowed)] [ServiceBehaviorAttribute(InstanceContextMode = InstanceContextMode::PerCall)] generic<typename T> public ref class DataService : IRequestHandler
Type Parameters
- T
Type that defines the data service.
The DataService<T> type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | DataService<T> | Creates a new data service that deploys data of the type indicated by the template class. |
| Name | Description | |
|---|---|---|
![]() | CurrentDataSource | Gets the data source instance currently being used to process the request. |
![]() | ProcessingPipeline | Gets an object that defines the events for the data service processing pipeline. |
| Name | Description | |
|---|---|---|
![]() | AttachHost | Attaches the data service host to the data service identified by the parameter host. |
![]() | CreateDataSource | Creates a data source of the template class that will be used by the data service. |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | 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.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | HandleException | Called when an exception is raised while processing a request. |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | OnStartProcessingRequest | Called before processing each request. For batch requests, it is called one time for the top batch request and one time for each operation in the batch. |
![]() | ProcessRequest | Processes an HTTP request. |
![]() | ProcessRequestForMessage | Processes an HTTP request. |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
The DataService<T> class does the basic integration of all components of the server system. A new data service that uses system defaults for authorization and caching is created by defining a class that derives from the DataService<T> class and by referencing a compatible data model.
The type of the DataService<T> must expose at least one property that returns an entity set that is an IQueryable<T> collection of entity types. This class must also implement the IUpdatable interface to enable updates to be made to entity resources.
