XmlSchemaDatatype Class
.NET Framework 3.0
The XmlSchemaDatatype class is an abstract class for mapping XML Schema definition language (XSD) types to Common Language Runtime (CLR) types.
Namespace: System.Xml.Schema
Assembly: System.Xml (in system.xml.dll)
Assembly: System.Xml (in system.xml.dll)
The following example shows use of the XmlSchemaDatatype class.
using System; using System.Xml; using System.Xml.Schema; class XMLSchemaExamples { public static void Main() { XmlTextReader xtr = new XmlTextReader("example.xsd"); XmlSchema schema = XmlSchema.Read(xtr, new ValidationEventHandler(ValidationCallbackOne)); XmlSchemaSet schemaSet = new XmlSchemaSet(); schemaSet.ValidationEventHandler += new ValidationEventHandler(ValidationCallbackOne); schemaSet.Add(schema); schemaSet.Compile(); XmlSchema compiledSchema = null; foreach (XmlSchema schema1 in schemaSet.Schemas()) { compiledSchema = schema1; } foreach (XmlSchemaObject schemaObject in compiledSchema.Items) { if (schemaObject.GetType() == typeof(XmlSchemaSimpleType)) { XmlSchemaSimpleType simpleType = (XmlSchemaSimpleType)schemaObject; Console.WriteLine("{0} {1}", simpleType.Name, simpleType.Datatype.ValueType); } if (schemaObject.GetType() == typeof(XmlSchemaComplexType)) { XmlSchemaComplexType complexType = (XmlSchemaComplexType)schemaObject; Console.WriteLine("{0} {1}", complexType.Name, complexType.Datatype.ValueType); } } xtr.Close(); } public static void ValidationCallbackOne(object sender, ValidationEventArgs args) { Console.WriteLine(args.Message); } }
The following XML file is used for the preceding code example.
