DataServiceContext.SetSaveStream Method (Object, Stream, Boolean, DataServiceRequestArgs)
Sets a new data stream as the binary property of an entity with the specified settings in the request message.
Assembly: System.Data.Services.Client (in System.Data.Services.Client.dll)
public void SetSaveStream( Object entity, Stream stream, bool closeStream, DataServiceRequestArgs args )
- Type: System.Object
The entity that has a binary property to which to assign the data stream.
- Type: System.Boolean
A Boolean value that determines whether the data stream is closed when the SaveChanges method is completed.
- Type: System.Data.Services.Client.DataServiceRequestArgs
An instance of the DataServiceRequestArgs class that contains settings for the HTTP request message.
The SetSaveStream method sets the binary stream that is the Media Resource that is associated with the entity, which is called a Media Link Entry.
Calling the SetSaveStream method marks the entity as a Media Link Entry. The entity state is also set to Modified so that the stream will be sent to the data service the next time that the SaveChanges method is called.
When closeStream is true, the SaveChanges method closes the stream before it returns. The stream is closed even when an error occurs and the stream is not read.
When the entity has the MediaEntryAttribute applied, the Media Resource cannot be a data stream. Remove this attribute before you try to set the data stream for the entity.
No validation is performed on the headers that are set in args. Therefore, do not change an HTTP header in a way that changes the meaning of the request.
