System.Data Namespace

---

Specifies how to write XML data and a relational schema from a DataSet.

Use the members of this enumeration when setting the WriteMode parameter of the WriteXml method.

Member Name	Description
DiffGram	Writes the entire DataSet as a DiffGram, including original and current values. To generate a DiffGram containing only changed values, call GetChanges, and then call WriteXml as a DiffGram on the returned DataSet. The DiffGram can be sent to an instance of SQL Server™ because it is a subset of an UpdateGram.
IgnoreSchema	Writes the current contents of the DataSet as XML data, without an XSD schema. If no data is loaded into the DataSet, nothing is written.
WriteSchema	Default. Writes the current contents of the DataSet as XML data with the relational structure as inline XSD schema. If the DataSet has only a schema with no data, only the inline schema is written. If the DataSet does not have a current schema, nothing is written.
