'ImportIncludeSample

The following XML is generated for this code example.

<?xml version="1.0" encoding="IBM437"?>
<schema elementFormDefault="qualified" targetNamespace="http://www.w3.org/2001/05/XMLInfoset" xmlns="http://www.w3.org/2001/XMLSchema">
  <import namespace="http://www.example.com/IPO" />
  <include schemaLocation="example.xsd" />
</schema>

Remarks

The included schema document must meet one of the following conditions:

The included schema must have the same target namespace as the containing schema document.

The included schema cannot have a specified targetNamespace; the targetNamespace attribute must be null.

XmlSchemaInclude adds all the schema components from included schemas that have the same target namespace (or no specified target namespace) to the containing schema.

Constructors

XmlSchemaInclude()

Initializes a new instance of the XmlSchemaInclude class.

Properties

Annotation	Gets or sets the `annotation` property.
Id	Gets or sets the string id. (Inherited from XmlSchemaExternal)

Namespaces	Gets or sets the XmlSerializerNamespaces to use with this schema object. (Inherited from XmlSchemaObject)
Parent	Gets or sets the parent of this XmlSchemaObject. (Inherited from XmlSchemaObject)
Schema	Gets or sets the `XmlSchema` for the referenced schema. (Inherited from XmlSchemaExternal)
SchemaLocation	Gets or sets the Uniform Resource Identifier (URI) location for the schema, which tells the schema processor where the schema physically resides. (Inherited from XmlSchemaExternal)
SourceUri	Gets or sets the source location for the file that loaded the schema. (Inherited from XmlSchemaObject)
UnhandledAttributes	Gets or sets the qualified attributes, which do not belong to the schema target namespace. (Inherited from XmlSchemaExternal)

Methods
