Serializing Kinect-Skeletons and transmitting them via MemoryMappedFiles to another process. These are just snippets and won't run without further Code.

MainWindow.xaml.cs

// This process uses the data comming from the kinect processes.


// Read from the MemoryMappedFile
MemoryMappedViewAccessor accessor = memoryMappedFile.createViewAccessor();
// Read to Array
accessor.ReadArray<byte>(0, mmf_result, 0, mmf_result.Length);

// Use a local Array for further instructions
byte[] temp = new byte[mmf_result.Length];
Array.Copy(mmf_result, temp, mmf_result.Length);

// Check if the Byte Array contains only 00-Bytes
empty = temp.All(B => B == default(Byte));

// if not: attempt to create a skelton
if(!empty)
{
  BinaryFormatter bf = new BinaryFormatter();
  MemoryStream ms = new MemoryStream(temp);
  Skeleton skelNew = (Skeleton)bf.Deserialize(ms);

  this.skeletons.Add(skelNew);
}

Porgram.cs

// This process is connected to the kinect.
// MemoryMappedFile has already been setup.
// Skeleton has already been loaded from the sensor.

Skeleton skel = this.skeletons[0];

// 1: Serialize Skeleton to Byte-Array 
BinaryFormatter bf = new BinaryFormatter();
MemoryStream ms = new MemoryStream();
bf.Serialize(ms, skel);

byte[] serializedSkel = ms.ToArray();
ms.Close();

// 2: Transmit Skeleton to MemoryMappedFile


// Transmit Skeleton Data
MemoryMappedViewAccessor writer = memoryMappedFile.createViewAccessor();
writer.WriteArray<byte>(0, serializedSkel, 0, serializedSkel.Length);

// If no Skeleton is available transmit an empty byte-array.
// Otherwise the last Skeleton will remain in the memory-mapped file forever.
byte[] empty = new byte[1] { 0 };
writer.WriteArray<byte>(0, empty, 0, empty.Length);
