无法转换为System.Guid

Question

尝试设置RavenDb 3.5和NServiceBus 6.在我发出了我在NServiceBus端点中设置的传奇之后，我输入了一个处理程序。一旦这个处理程序完成，我得到这个错误消息。

System.ArgumentException：无法转换身份键入的System.Guid因为在公约IdentityTypeConvertors注册不匹配的类型转换器

我的代码：

public static class AutoFacConfig 
{ 
    public static IContainer ConfigureAutofac() 
    { 
     var builder = new ContainerBuilder(); 

     var resourceManagerId = new Guid("6c9abcbb-c7ca-4a67-a149-5142f633f535"); 

     var dtcRecoveryBasePath = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData); 
     var recoveryPath = Path.Combine(dtcRecoveryBasePath, "NServiceBus.RavenDB", resourceManagerId.ToString()); 

     builder.Register(x => 
     { 
      var store = new DocumentStore 
      { 
       ConnectionStringName = "RavenDB", 
       ResourceManagerId = resourceManagerId, 
       TransactionRecoveryStorage = new LocalDirectoryTransactionRecoveryStorage(recoveryPath) 
      }; 
      store.DefaultDatabase = "MyDB"; 
      store.Initialize(); 
      store.Conventions.IdentityPartsSeparator = "-"; 
      var _guidTypeConvertor = store.Conventions 
       .IdentityTypeConvertors 
       .FirstOrDefault(id => id.CanConvertFrom(typeof(Guid))); 
      if (_guidTypeConvertor != null) 
       store.Conventions.IdentityTypeConvertors.Remove(_guidTypeConvertor); 
      return store; 
     }) 
      .As<IDocumentStore>() 
      .SingleInstance(); 

     builder.Register<IFilesStore>(x => 
     { 
      var fileStore = new FilesStore() 
      { 
       Url = "http://localhost:40000", 
       DefaultFileSystem = "MyFS", 
      }.Initialize(); 
      return fileStore; 
     }).SingleInstance(); 

     return builder.Build(); 
    } 
} 

在传奇：

protected override void ConfigureHowToFindSaga(SagaPropertyMapper<FileToOrderSagaData> mapper) 
    { 
     mapper.ConfigureMapping<StartFileToOrderSagaCommand>(m => m.DataId) 
      .ToSaga(s => s.DataId); 
    } 

    public async Task Handle(StartFileToOrderSagaCommand message, IMessageHandlerContext context) 
    { 
     // Do Validation ValidateXmlCommand 
     Data.DataId = message.DataId; 
     await context.Send<ValidateXmlCommand>(x => { x.Filename = message.Filename; x.CustomerId = message.CustomerId; }); 
    } 

以下是堆栈跟踪：

搜索了全部找出abt这个，但我不知道这个Guid和转换器是什么。

任何帮助家伙？ Thx

Answer 1

store.Conventions.IdentityTypeConvertors.Remove(_guidTypeCon‌​vertor); 

正在删除Guid类型转换器。这就是为什么你遇到：

System.ArgumentException：无法转换身份键入 的System.Guid因为没有匹配的类型转换器在 登记公约IdentityTypeConvertors

你应该删除该行代码。
