ITable.GetOriginalEntityState Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Retrieves original values.

Namespace:  System.Data.Linq
Assembly:  System.Data.Linq (in System.Data.Linq.dll)

Syntax

'Declaration
Function GetOriginalEntityState ( _
    entity As Object _
) As Object

Object GetOriginalEntityState(
    Object entity
)

Parameters

  • entity
    Type: System.Object
    The entity whose original value is to be retrieved.

Return Value

Type: System.Object
A copy of the original entity. The value is null if the entity passed in is not tracked. Disconnected entities sent back by a client must be attached before the DataContext can begin to track their state. The "original state" of a newly attached entity is established based on values supplied by the client. The data context does not track the state of disconnected entities.

Remarks

Note the following:

  • The entity argument must be non-null. Otherwise, a null argument exception is thrown.

  • In the case of the strongly typed (TEntity) method, the type must be mapped and must be an entity type. That is, it must have object ID information in its mapping. Otherwise, a wrong type exception is thrown.
