XmlSchemaObject Class
Represents the root class for the Xml schema object model hierarchy and serves as a base class for classes such as the XmlSchema class.
Assembly: System.Xml (in System.Xml.dll)
The XmlSchemaObject type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() | LineNumber | Gets or sets the line number in the file to which the schema element refers. |
![]() ![]() | LinePosition | Gets or sets the line position in the file to which the schema element refers. |
![]() ![]() | Namespaces | Gets or sets the XmlSerializerNamespaces to use with this schema object. |
![]() ![]() | Parent | Gets or sets the parent of this XmlSchemaObject. |
![]() ![]() | SourceUri | Gets or sets the source location for the file that loaded the schema. |
| 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.) |
The following example displays each schema object.
