DataServiceContext.AddObject Method

Adds the specified object to the set of objects that the DataServiceContext is tracking.

Namespace:  System.Data.Services.Client
Assembly:  System.Data.Services.Client (in System.Data.Services.Client.dll)

public void AddObject(
	string entitySetName,
	Object entity
)

Parameters

entitySetName
Type: System.String
The name of the entity set to which the resource will be added.
entity
Type: System.Object
The resource to be tracked by the DataServiceContext in the added state.

ExceptionCondition
ArgumentNullException

When entitySetName or entity is null.

ArgumentException

When entitySetName is an empty string.

-or-

When entity does not have a key property.

InvalidOperationException

When entity is already being tracked by the context.

The object is put into the tracking set of the DataServiceContext in the added state. The DataServiceContext will try to insert the object by HTTP POST on the next call to BeginSaveChanges. This method does not add objects related to the specified entity to the DataServiceContext. Each object must be added by making a separate call to AddObject.

The method does not validate that the entity set specified exists in the data service associated with the DataServiceContext or that the added object has the required properties needed to be added to the specified entity set.
