SerializationBinder также был моим решением. Но у меня есть класс в DLL, на который ссылаются. Поэтому я должен искать во всех загрузочных сборках. Я изменил bevor ответов с параметром, если связыватель должен искать в dll.
using System;
using System.Collections.Generic;
using System.IO;

using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;
namespace ibKastl.Helper
{
public static class BinaryFormatterHelper
{
public static T Read<T>(string filename, Assembly currentAssembly)
{
T retunValue;
FileStream fileStream = new FileStream(filename, FileMode.Open);
try
{
BinaryFormatter binaryFormatter = new BinaryFormatter();
binaryFormatter.Binder = new SearchAssembliesBinder(currentAssembly,true);
retunValue = (T)binaryFormatter.Deserialize(fileStream);
}
finally
{
fileStream.Close();
}
return retunValue;
}
public static void Write<T>(T obj, string filename)
{
FileStream fileStream = new FileStream(filename, FileMode.Create);
BinaryFormatter formatter = new BinaryFormatter();
try
{
formatter.Serialize(fileStream, obj);
}
finally
{
fileStream.Close();
}
}
}
sealed class SearchAssembliesBinder : SerializationBinder
{
private readonly bool _searchInDlls;
private readonly Assembly _currentAssembly;
public SearchAssembliesBinder(Assembly currentAssembly, bool searchInDlls)
{
_currentAssembly = currentAssembly;
_searchInDlls = searchInDlls;
}
public override Type BindToType(string assemblyName, string typeName)
{
List<AssemblyName> assemblyNames = new List<AssemblyName>();
assemblyNames.Add(_currentAssembly.GetName()); // EXE
if (_searchInDlls)
{
assemblyNames.AddRange(_currentAssembly.GetReferencedAssemblies()); // DLLs
}
foreach (AssemblyName an in assemblyNames)
{
var typeToDeserialize = GetTypeToDeserialize(typeName, an);
if (typeToDeserialize != null)
{
return typeToDeserialize; // found
}
}
return null; // not found
}
private static Type GetTypeToDeserialize(string typeName, AssemblyName an)
{
string fullTypeName = string.Format("{0}, {1}", typeName, an.FullName);
var typeToDeserialize = Type.GetType(fullTypeName);
return typeToDeserialize;
}
}
}
Использование:
const string FILENAME = @"MyObject.dat";
// Serialize
BinaryFormatterHelper.Write(myObject1,FILENAME);
// Deserialize
MyObject myObject2 = BinaryFormatterHelper.Read<MyObject>(FILENAME, Assembly.GetExecutingAssembly()); // Current Assembly where the dll is referenced
