Returns the data stream of the field.
Assembly: Microsoft.BusinessData (in Microsoft.BusinessData.dll)
From each StreamableField, the data stream can be accessed via the GetData method, which will invoke the StreamAccessor MethodInstance with the same name as the StreamableField.
The GetData method invokes the StreamAccessor to obtain a new stream every time it is invoked. Calling this method multiple times may cause an unnecessary load in the external system.
Streams obtained via the GetData method should be closed and disposed by the caller. Streams that are not closed or disposed may leak resources.
