## Methods

### GetPoints()

Gets the points.

```csharp
public override IEnumerable<SplineData.Point> GetPoints()

```

#### Returns

[IEnumerable](https://learn.microsoft.com/dotnet/api/system.collections.generic.ienumerable-1)&lt;[SplineData](VM.Managed.DAFUL.SplineData.md).[Point](VM.Managed.DAFUL.SplineData.Point.md)&gt;

The point list.

### GetPoints(string)

Gets the points.

```csharp
public override IEnumerable<SplineData.Point> GetPoints(string documentFilePath)

```

#### Parameters

`documentFilePath` [string](https://learn.microsoft.com/dotnet/api/system.string)

The Document file path.

#### Returns

[IEnumerable](https://learn.microsoft.com/dotnet/api/system.collections.generic.ienumerable-1)&lt;[SplineData](VM.Managed.DAFUL.SplineData.md).[Point](VM.Managed.DAFUL.SplineData.Point.md)&gt;

The point list.

### GetPoints(List&lt;double&gt;, List&lt;double&gt;)

Gets the points.

```csharp
public override void GetPoints(List<double> lstX, List<double> lstY)

```

#### Parameters

`lstX` [List](https://learn.microsoft.com/dotnet/api/system.collections.generic.list-1)&lt;[double](https://learn.microsoft.com/dotnet/api/system.double)&gt;

`strDocumentFilePath` [string](https://learn.microsoft.com/dotnet/api/system.string)

The Document file path.

### GetSchema()

This method is reserved and should not be used. When implementing the IXmlSerializable interface, you should return null (Nothing in Visual Basic) from this method, and instead, if specifying a custom schema is required, apply the  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  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  stream to which the object is serialized.
