Remarks
Simple types are defined by deriving them from existing simple types (built-in data types and derived simple types). A simple type cannot contain elements and cannot have attributes.
Constructors
XmlSchemaSimpleType() |
Initializes a new instance of the XmlSchemaSimpleType class. |
Properties
Annotation |
Gets or sets the |
BaseSchemaType |
Obsolete.
Obsolete.
Obsolete.

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 |
LinePosition |
Gets or sets the line position in the file to which the |
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 |
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) |
Methods
Equals(Object) |
Determines whether the specified object is equal to the current object. (Inherited from Object) |
GetHashCode() |
Serves as the default hash function. (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) |
