Reads a DiffGram, applying changes from the DiffGram to the System.Data.DataSet. The semantics are identical to those of a DataSet.Merge(DataSet) operation. As with the DataSet.Merge(DataSet) operation, DataRow.RowState values are preserved. Input to DataSet.ReadXml(System.Xml.XmlReader) with DiffGrams should only be obtained using the output from DataSet.WriteXml(System.IO.Stream) as a DiffGram.
Syntax
XmlReadMode DiffGram
Remarks
The target System.Data.DataSet must have the same schema as the System.Data.DataSet on which DataSet.WriteXml(System.IO.Stream) as DiffGram is called. Otherwise the DiffGram merge operation fails, and an exception is thrown.
