Sto tentando di creare un codice che può serializzare e deserializzare una libreria di classi in un disegno AutoCAD. Questa domanda ha poco a che vedere con AutoCAD se non perché non è possibile eseguirne il debug con mezzi normali. Ho iniziato questo progetto da this article e ho ottenuto con successo il suo codice per l'esecuzione. Comunque il modo in cui il suo codice è strutturato, mi richiederebbe che tutte le mie classi ereditassero dal suo oggetto base. Poiché questo è chiaramente un odore di codice, sapevo che avevo bisogno di creare un'interfaccia invece. Di seguito è il codice che ho finito con.Codice di serializzazione causa eccezione non gestita
Questa prima sezione è il codice responsabile della serializzazione in un disegno AutoCAD.
La seconda sezione è un esempio di una classe che implementa mia abitudine interfaccia serializzazione
public class Commands
{
public class MyUtil
{
const int kMaxChunkSize = 127;
public ResultBuffer StreamToResBuf(MemoryStream ms, string appName)
{
ResultBuffer resBuf = new ResultBuffer(new TypedValue((int)DxfCode.ExtendedDataRegAppName, appName));
for (int i = 0; i < ms.Length; i += kMaxChunkSize)
{
int length = (int)Math.Min(ms.Length - i, kMaxChunkSize);
byte[] datachunk = new byte[length];
ms.Read(datachunk, 0, length);
resBuf.Add(new TypedValue((int)DxfCode.ExtendedDataBinaryChunk, datachunk));
}
return resBuf;
}
public MemoryStream ResBufToStream(ResultBuffer resBuf)
{
MemoryStream ms = new MemoryStream();
TypedValue[] values = resBuf.AsArray();
// Start from 1 to skip application name
for (int i = 1; i < values.Length; i++)
{
byte[] datachunk = (byte[])values[i].Value;
ms.Write(datachunk, 0, datachunk.Length);
}
ms.Position = 0;
return ms;
}
public void NewFromEntity(IClearspanSerializable objectToSave, Entity ent)
{
using (ResultBuffer resBuf = ent.GetXDataForApplication("Member"))
{
BinaryFormatter bf = new BinaryFormatter();
bf.Binder = new MyBinder();
MemoryStream ms = this.ResBufToStream(resBuf);
objectToSave.SetObjectData(bf.Deserialize(ms));
}
}
public void SaveToEntity(IClearspanSerializable objectToSave, Entity ent)
{
// Make sure application name is registered
// If we were to save the ResultBuffer to an Xrecord.Data,
// then we would not need to have a registered application name
Transaction tr = ent.Database.TransactionManager.TopTransaction;
RegAppTable regTable = (RegAppTable)tr.GetObject(ent.Database.RegAppTableId, OpenMode.ForWrite);
if (!regTable.Has("Member"))
{
RegAppTableRecord app = new RegAppTableRecord();
app.Name = "Member";
regTable.Add(app);
tr.AddNewlyCreatedDBObject(app, true);
}
BinaryFormatter bf = new BinaryFormatter();
MemoryStream ms = new MemoryStream();
bf.Serialize(ms, objectToSave);
ms.Position = 0;
ent.XData = this.StreamToResBuf(ms, "Member");;
}
}
public sealed class MyBinder : SerializationBinder
{
public override Type BindToType(string assemblyName, string typeName)
{
return Type.GetType(string.Format("{0}, {1}",
typeName, assemblyName));
}
}
[CommandMethod("SaveClassToEntityXData", CommandFlags.Modal)]
public void SaveClassToEntityXData(IClearspanSerializable objectToSerialize)
{
Database db = Application.DocumentManager.MdiActiveDocument.Database;
Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;
PromptEntityResult per = ed.GetEntity("Select entity to save class to:\n");
if (per.Status != PromptStatus.OK)
return;
MyUtil util = new MyUtil();
// Save it to the document
using (Transaction tr = db.TransactionManager.StartTransaction())
{
Entity ent = (Entity)tr.GetObject(per.ObjectId, OpenMode.ForWrite);
util.SaveToEntity(objectToSerialize, ent);
tr.Commit();
}
// Write some info about the results
//ed.WriteMessage("Content of MyClass we serialized:\n {0} \n", mc.ToString());
}
[CommandMethod("GetClassFromEntityXData", CommandFlags.Modal)]
public void GetClassFromEntityXData(IClearspanSerializable objectToRestore)
{
Database db = Application.DocumentManager.MdiActiveDocument.Database;
Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;
MyUtil util = new MyUtil();
PromptEntityResult per = ed.GetEntity("Select entity to get class from:\n");
if (per.Status != PromptStatus.OK)
return;
// Get back the class
using (Transaction tr = db.TransactionManager.StartTransaction())
{
Entity ent = (Entity)tr.GetObject(per.ObjectId, OpenMode.ForRead);
util.NewFromEntity(objectToRestore, ent);
tr.Commit();
}
}
}
Ecco una classe fittizia che sto cercando di testare con:
[Serializable]
public class MattMember: IClearspanSerializable
{
public string Name;
List<int> MattsInts;
public MattMember(string passedName, List<int> passedInts)
{
Name = passedName;
MattsInts = passedInts;
}
[SecurityPermission(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.SerializationFormatter)]
public void GetObjectData(SerializationInfo info, StreamingContext context)
{
info.AddValue("Name", Name);
info.AddValue("MattsInts", MattsInts);
}
[SecurityPermission(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.SerializationFormatter)]
public void SetObjectData(SerializationInfo info, StreamingContext context)
{
if (info == null)
{
throw new System.ArgumentNullException("info");
}
Name = (string)info.GetValue("Name", typeof(string));
MattsInts = (List<int>)info.GetValue("MattsInts", typeof(List<int>));
}
void IClearspanSerializable.SetObjectData(object objectInDisguise)
{
if (objectInDisguise == null)
{
throw new System.ArgumentNullException("info");
}
MattMember objectToCopy = (MattMember)objectInDisguise;
Name = objectToCopy.Name;
MattsInts = objectToCopy.MattsInts;
}
}
e qui è l'interfaccia :
public interface IClearspanSerializable
{
void GetObjectData(SerializationInfo info, StreamingContext context);
void SetObjectData(object objectInDisguise);
}
Quando si tenta di eseguire il codice all'interno di AutoCAD, tutto ciò che ottengo è err o. Il che mi porta a credere che ci sia un bug nella mia inizializzazione delle mie lezioni. Non vengono colpiti i miei punti di interruzione.
Come devo eseguire il debug di questo? e dove ho rovinato la mia inizializzazione?
