| ctor #1 | Default constructor. This constructor is called by derived class constructors to initialize state in this type. |
| Annotation (inherited from System.Xml.Schema.XmlSchemaAnnotated) |
Read-write See base class member description: System.Xml.Schema.XmlSchemaAnnotated.Annotation Gets or sets the annotation property. |
| AttributeType | Read-only Gets the common runtime library (CLR) object based on the XmlSchemaAttribute.SchemaType or XmlSchemaAttribute.SchemaTypeName of the attribute that holds the post-compilation value of the AttributeType property. |
| DefaultValue | Read-write Gets or sets the default value for the attribute. |
| FixedValue | Read-write Gets or sets the fixed value for the attribute. |
| Form | Read-write Gets or sets the form for the attribute. |
| Id (inherited from System.Xml.Schema.XmlSchemaAnnotated) |
Read-write See base class member description: System.Xml.Schema.XmlSchemaAnnotated.Id Gets or sets the string id. |
| LineNumber (inherited from System.Xml.Schema.XmlSchemaObject) |
Read-write See base class member description: System.Xml.Schema.XmlSchemaObject.LineNumber Gets or sets the line number in the file to which the schema element refers. |
| LinePosition (inherited from System.Xml.Schema.XmlSchemaObject) |
Read-write See base class member description: System.Xml.Schema.XmlSchemaObject.LinePosition Gets or sets the line position in the file to which the schema element refers. |
| Name | Read-write Gets or sets the name of the attribute. |
| Namespaces (inherited from System.Xml.Schema.XmlSchemaObject) |
Read-write See base class member description: System.Xml.Schema.XmlSchemaObject.Namespaces |
| QualifiedName | Read-only Gets the qualified name for the attribute which holds the post-compilation value of the QualifiedName property. |
| RefName | Read-write Gets or sets the name of an attribute declared in this schema (or another schema indicated by the specified namespace). |
| SchemaType | Read-write Gets or sets the attribute type to a simple type. |
| SchemaTypeName | Read-write Gets or sets the name of the simple type defined in this schema (or another schema indicated by the specified namespace). |
| SourceUri (inherited from System.Xml.Schema.XmlSchemaObject) |
Read-write See base class member description: System.Xml.Schema.XmlSchemaObject.SourceUri Gets or sets the source location for the file that loaded the schema. |
| UnhandledAttributes (inherited from System.Xml.Schema.XmlSchemaAnnotated) |
Read-write See base class member description: System.Xml.Schema.XmlSchemaAnnotated.UnhandledAttributes Gets or sets the qualified attributes that do not belong to the schema target namespace. |
| Use | Read-write Gets or sets information about how the attribute is used. |
| Equals (inherited from System.Object) |
See base class member description: System.Object.Equals Derived from System.Object, the primary base class for all objects. |
| GetHashCode (inherited from System.Object) |
See base class member description: System.Object.GetHashCode Derived from System.Object, the primary base class for all objects. |
| GetType (inherited from System.Object) |
See base class member description: System.Object.GetType Derived from System.Object, the primary base class for all objects. |
