Inferring Schema

In some circumstances you may want to load XML data into an empty DataSet while ignoring the schema information in the XML.

If the XML data loaded into an empty DataSet has no schema information, then the schema is inferred automatically. To explicitly ask that the schema be inferred, call DataSet.ReadXml(XmlReader, XmlReadMode). Pass XmlReadMode.InferSchema as an argument. See these snippets, for example:

 C# l_XmlTextReader = new System.Xml.XmlTextReader(new System.IO.StreamReader ...
