SQL Server Native UDT Serialization Format

I have created a UDT Point from an MSDN example. Its declaration is the following:




Code Snippet [Serializable]
[Microsoft.SqlServer.Server.SqlUserDefinedType(Format.Native,
IsByteOrdered = true, ValidationMethodName = "ValidatePoint")]
public struct Point : INullable
{
private bool is_Null;
private Int32 _x;
private Int32 _y;
...


So it means that this class will be serialized in the native SQL Server format.
Is there any possibility to deserialize data retrieved from server as bytes to an object instance?
For example:



Code Snippet SqlDataReader rdr = cmd.ExecuteReader();

while (rdr.Read())
{
// Retrieve the raw bytes into a byte array
byte[] buffer = new byte[32];
long byteCount = rdr.GetBytes(1, 0, buffer, 0, 32);
Point pt = new Point();
// Here I need to fill the created object with retrieved data
}


After I retrieved the data in bytes format, I need to write it to the object. How can I do this? In fact, I have no possibility to use SqlDataReader in the following manner:



Code Snippet // Retrieve the value of the UDT
Point pnt = (Point)rdr[1];
// Point pnt = (Point)rdr.GetSqlValue(1);
// Point pnt = (Point)rdr.GetValue(1);



because I retrieve data in bytes not from the server, but from an unmanaged application.
I have a possibility to create an instance of the class, but how can I fill this instance with data? Is it possible to do using native SQL Server native format? How can I do this when UDT uses user defined serialization?
