XmlSchemaDatatype Class

The XmlSchemaDatatype class is an abstract class for mapping XML Schema definition language (XSD) types to Common Language Runtime (CLR) types.

System.Object
  System.Xml.Schema.XmlSchemaDatatype

Namespace:  System.Xml.Schema
Assembly:  System.Xml (in System.Xml.dll)

public abstract class XmlSchemaDatatype

The XmlSchemaDatatype type exposes the following members.

  NameDescription
Protected methodSupported by the XNA FrameworkXmlSchemaDatatypeInitializes a new instance of the XmlSchemaDatatype class.
Top

  NameDescription
Public propertySupported by the XNA FrameworkTokenizedTypeWhen overridden in a derived class, gets the type for the string as specified in the World Wide Web Consortium (W3C) XML 1.0 specification.
Public propertySupported by the XNA FrameworkTypeCodeGets the XmlTypeCode value for the simple type.
Public propertySupported by the XNA FrameworkValueTypeWhen overridden in a derived class, gets the Common Language Runtime (CLR) type of the item.
Public propertySupported by the XNA FrameworkVarietyGets the XmlSchemaDatatypeVariety value for the simple type.

  NameDescription
Public methodSupported by the XNA FrameworkChangeType(Object, Type)Converts the value specified, whose type is one of the valid Common Language Runtime (CLR) representations of the XML schema type represented by the XmlSchemaDatatype, to the CLR type specified.
Public methodSupported by the XNA FrameworkChangeType(Object, Type, IXmlNamespaceResolver)Converts the value specified, whose type is one of the valid Common Language Runtime (CLR) representations of the XML schema type represented by the XmlSchemaDatatype, to the CLR type specified using the IXmlNamespaceResolver if the XmlSchemaDatatype represents the xs:QName type or a type derived from it.
Public methodSupported by the XNA FrameworkEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodSupported by the XNA FrameworkFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodSupported by the XNA FrameworkGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodSupported by the XNA FrameworkGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodSupported by the XNA FrameworkIsDerivedFromThe IsDerivedFrom method always returns false.
Protected methodSupported by the XNA FrameworkMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodSupported by the XNA FrameworkParseValueWhen overridden in a derived class, validates the string specified against a built-in or user-defined simple type.
Public methodSupported by the XNA FrameworkToStringReturns a string that represents the current object. (Inherited from Object.)

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.


<?xml version="1.0"?>

    <xs:simpleType name="LotteryNumber">
        <xs:restriction base="xs:int">

            <xs:maxInclusive value="99"/>
        </xs:restriction>
    </xs:simpleType>
</xs:schema>
