XmlSchemaSimpleContent Class

Class for simple types and complex types with a simple content model. Represents the World Wide Web Consortium (W3C) simpleContent element.

For a list of all members of this type, see XmlSchemaSimpleContent Members.

System.Object
   System.Xml.Schema.XmlSchemaObject
      System.Xml.Schema.XmlSchemaAnnotated
         System.Xml.Schema.XmlSchemaContentModel
            System.Xml.Schema.XmlSchemaSimpleContent

[Visual Basic]
Public Class XmlSchemaSimpleContent
   Inherits XmlSchemaContentModel
[C#]
public class XmlSchemaSimpleContent : XmlSchemaContentModel
[C++]
public __gc class XmlSchemaSimpleContent : public
   XmlSchemaContentModel
[JScript]
public class XmlSchemaSimpleContent extends XmlSchemaContentModel

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

Remarks

XmlSchemaSimpleContent is used to indicate that the content model of the new type contains only character data and no elements. It does this through XmlSchemaSimpleContentExtension or XmlSchemaSimpleContentRestriction.

Example

[Visual Basic, C#, C++] The following example shows the XmlSchemaSimpleContent class.
