Public Shared Sub WriteBinary( _
   ByVal ds As DataSet, _
   ByVal str As Stream _
) 

public static void WriteBinary( 
   DataSet ds,
   Stream str
)

Parameters

ds

The DataSet to write to the stream

str

The stream which will receive the binary from the DataSet

WriteBinary writes the DataSet using a specific binary encoding scheme which can only be read by ReadBinary.

WriteBinary encodes the version of DataSetSurrogate that was used to produce the stream so as to avoid version and binary format conflicts with newer or older versions. If ReadBinary encounters a newer or older stream, it will return null signifying that the cache data is no longer valid and needs to be refreshed.

IMPORTANT: The ReadBinary and WriteBinary methods only support simple DataSets with tables, columns, rows (with data) and relationships. All other information will be lost. This includes keys, constraints, extended properties, etc
