Remarks

Use the LoadFromStream method to load the diagram’s layout from a stream. If the specified stream is empty or null (Nothing in Visual Basic), an exception is raised. To save the diagram layout to a stream, use the SankeyDiagramControl.SaveToStream method.

The following code saves the diagram’s layout to a stream, and then loads the layout from the stream:

C#

using System.IO;
//...

  Stream stream = new MemoryStream();

  // Save the diagram.
  stream.Seek(0, System.IO.SeekOrigin.Begin);
  sankeyDiagramControl1.SaveToStream(stream);

  // Load the diagram.
  stream.Seek(0, System.IO.SeekOrigin.Begin);
  sankeyDiagramControl1.LoadFromStream(stream);

VB.NET

Imports System.IO
'...
    Dim stream As Stream = New MemoryStream()

    ' Save the diagram.
    stream.Seek(0, SeekOrigin.Begin)
    sankeyDiagramControl1.SaveToStream(stream)

    ' Load the diagram.
    stream.Seek(0, SeekOrigin.Begin)
    sankeyDiagramControl1.LoadFromStream(stream)
