XmlSchemaSimpleType Class
Represents the simpleType element for simple content from XML Schema as specified by the . This class defines a simple type. Simple types can specify information and constraints for the value of attributes or elements with text-only content.

The XmlSchemaSimpleType type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() | Annotation | Gets or sets the annotation property. (Inherited from XmlSchemaAnnotated.) |
![]() ![]() | BaseSchemaType | Obsolete. Gets the post-compilation object type or the built-in XML Schema Definition Language (XSD) data type, simpleType element, or complexType element. This is a post-schema-compilation infoset property. (Inherited from XmlSchemaType.) |
![]() ![]() | BaseXmlSchemaType | Gets the post-compilation value for the base type of this schema type. (Inherited from XmlSchemaType.) |
![]() ![]() | Content | Gets or sets one of XmlSchemaSimpleTypeUnion, XmlSchemaSimpleTypeList, or XmlSchemaSimpleTypeRestriction. |
![]() ![]() | Datatype | Gets the post-compilation value for the data type of the complex type. (Inherited from XmlSchemaType.) |
![]() ![]() | DerivedBy | Gets the post-compilation information on how this element was derived from its base type. (Inherited from XmlSchemaType.) |
![]() ![]() | Final | Gets or sets the final attribute of the type derivation that indicates if further derivations are allowed. (Inherited from XmlSchemaType.) |
![]() ![]() | FinalResolved | Gets the post-compilation value of the Final property. (Inherited from XmlSchemaType.) |
![]() ![]() | Id | Gets or sets the string id. (Inherited from XmlSchemaAnnotated.) |
![]() ![]() | IsMixed | Gets or sets a value indicating if this type has a mixed content model. This property is only valid in a complex type. (Inherited from XmlSchemaType.) |
![]() ![]() | LineNumber | Gets or sets the line number in the file to which the schema element refers. (Inherited from XmlSchemaObject.) |
![]() ![]() | LinePosition | Gets or sets the line position in the file to which the schema element refers. (Inherited from XmlSchemaObject.) |
![]() ![]() | Name | Gets or sets the name of the type. (Inherited from XmlSchemaType.) |
![]() ![]() | 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.) |
![]() ![]() | QualifiedName | Gets the qualified name for the type built from the Name attribute of this type. This is a post-schema-compilation property. (Inherited from XmlSchemaType.) |
![]() ![]() | SourceUri | Gets or sets the source location for the file that loaded the schema. (Inherited from XmlSchemaObject.) |
![]() ![]() | TypeCode | Gets the XmlTypeCode of the type. (Inherited from XmlSchemaType.) |
![]() ![]() | UnhandledAttributes | Gets or sets the qualified attributes that do not belong to the current schema's target namespace. (Inherited from XmlSchemaAnnotated.) |
| Name | Description | |
|---|---|---|
![]() ![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() ![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() ![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() ![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() ![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
