System.Xml.Schema.XmlSchemaDatatype Class

Assembly: System.Xml.dll
Namespace: System.Xml.Schema
Summary
Represents the abstract class for mapping XML Schema definition language (XSD) and .NET Framework types.
C# Syntax:
public abstract class XmlSchemaDatatype
Example
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));

        schema.Compile(new ValidationEventHandler(ValidationCallbackOne));
		
		foreach (XmlSchemaObject schemaObject in schema.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.

<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:simpleType name="LotteryNumber">
        <xs:restriction base="xs:int">
            <xs:minInclusive value="1"/>
            <xs:maxInclusive value="99"/>
        </xs:restriction>
    </xs:simpleType>
</xs:schema>
