EditStreamUri | Gets or sets the URI that modifies the binary property data of the entity. |
|
|
Entity | Gets the entity that contains the update data. |
|
|
ETag | Gets an eTag value that indicates the state of data targeted for update since the last call to SaveChanges. |
|
|
Identity | Gets or sets the URI that is the identity value of the entity. |
|
|
ParentForInsert | Gets the parent entity that is related to the entity. |
|
|
ParentPropertyForInsert | Gets the name of the property of the entity that is a navigation property and links to the parent entity. |
|
|
ReadStreamUri | Gets or sets the URI that accesses the binary property data of the entity. |
|
|
SelfLink | Gets or sets the URI that is used to return the entity resource. |
|
|
ServerTypeName | Gets or sets the name of the type in the data source to which the entity is mapped. |
|
|
State | When overridden in a derived class, gets the state of the object at the time this instance was constructed. (Inherited from Descriptor.) |

StreamETag | Gets the eTag for the media resource associated with an entity that is a media link entry. |
| Name | Description | |
|---|---|---|
|
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.) |
|
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
|
ToString | Returns a string that represents the current object. (Inherited from Object.) |
The SaveChanges method returns a DataServiceResponse object that contains a series of OperationResponse objects each of which contains a sequence of EntityDescriptor or LinkDescriptor instances that represent changes that were persisted.
For successful operations, the State() property of the descriptor will be set to unchanged and the new values for insert and update operations will be merged according to the merge settings.
For operations with errors, the State() of the descriptor will remain the same as it was before SaveChanges was called.
If an error occurred and processing stopped during an operation, the State() will remain unchanged.
