Loosing XML Schema when writing DataSet to XML

[ertanasan1]

Hi,

//Returns a new dataset with tree datatables.
dsTemp.ReadXmlSchema(@"C:\mysch.xsd");

//Add a row to data table 0
DataRow dr = dsTemp.Tables[0].NewRow();
dr["field1"] = "value1";
dsTemp.Tables[0].Rows.Add(dr);

//write dataset to xml
System.IO.StringWriter stream = new System.IO.StringWriter();
dsTemp.WriteXml(stream);
string xmlTemp = stream.ToString();

When writing to xml, it looses schema information. The output xml is
not competible with mysch.xsd which has been read at first.

What would be the reason?

Thanks.

Ertan,

Have you tried the overload of WriteXml that takes a value from the
XmlWriteMode enumeration? You would want to pass the WriteSchema value to
the method.

Hope this helps.

Nick,

WriteSchema enum value forces WriteXml method write only the schema
information, not the data.

Thanks anyway.
