Direction type(x,y,z). ### DirectionLink() Initializes a new instance of the class. ```csharp public DirectionLink() ``` ## Fields ### m\_linkDirectionContainer ```csharp protected Link m_linkDirectionContainer ``` #### Field Value [Link](VM.Managed.Link-4.md)<[IDirectionContainer](VM.Managed.IDirectionContainer.md), [LinkContainer](VM.Managed.LinkContainer.md).[Update](VM.Managed.LinkContainer.Update.md), [LinkContainer](VM.Managed.LinkContainer.md).[Destroy](VM.Managed.LinkContainer.Destroy.md), [LinkContainer](VM.Managed.LinkContainer.md).[None](VM.Managed.LinkContainer.None.md)> ### m\_strDirectionType ```csharp protected string m_strDirectionType ``` #### Field Value [string](https://learn.microsoft.com/dotnet/api/system.string) ## Properties ### DirectionContainer Gets or sets the object of design frame. ```csharp public IDirectionContainer DirectionContainer { get; set; } ``` #### Property Value [IDirectionContainer](VM.Managed.IDirectionContainer.md) ### DirectionType Gets the direction type of design frame. ```csharp public string DirectionType { get; } ``` #### Property Value [string](https://learn.microsoft.com/dotnet/api/system.string) ### IsParameterized Gets the parametric. ```csharp public override bool IsParameterized { get; } ``` #### Property Value [bool](https://learn.microsoft.com/dotnet/api/system.boolean) ### Position Gets the position of design frame. ```csharp public VectorBase Position { get; } ``` #### Property Value [VectorBase](VM.Managed.VectorBase.md) ### Value Gets the VectorBase(x, y, z). ```csharp public override VectorBase Value { get; } ``` #### Property Value [VectorBase](VM.Managed.VectorBase.md) ### \_DirectionContainer Gets or sets the object of design frame. ```csharp public Linker _DirectionContainer { get; set; } ``` #### Property Value [Linker](VM.Managed.Linker-1.md)<[IDirectionContainer](VM.Managed.IDirectionContainer.md)> ## Methods ### GetSchema() This method is reserved and should not be used. When implementing the IXmlSerializable interface, you should return nullNothingnullptra null reference (Nothing in Visual Basic) (Nothing in Visual Basic) from this method, and instead, if specifying a custom schema is required, apply the XmlSchemaProviderAttribute to the class. ```csharp public override XmlSchema GetSchema() ``` #### Returns [XmlSchema](https://learn.microsoft.com/dotnet/api/system.xml.schema.xmlschema) An that describes the XML representation of the object that is produced by the method and consumed by the method. ### ReadXml(XmlReader) Generates an object from its XML representation. ```csharp public override void ReadXml(XmlReader reader) ``` #### Parameters `reader` [XmlReader](https://learn.microsoft.com/dotnet/api/system.xml.xmlreader) The XmlReader stream from which the object is deserialized. ### WriteXml(XmlWriter) Converts an object into its XML representation. ```csharp public override void WriteXml(XmlWriter writer) ``` #### Parameters `writer` [XmlWriter](https://learn.microsoft.com/dotnet/api/system.xml.xmlwriter) The XmlWriter stream to which the object is serialized.
