C# Bot仿真器框架无法解析服务

我遵循Azure EchoBot教程添加状态，在bot框架模拟器中运行bot时遇到了一个问题。 （机器人可以连接。EchoBot无需任何修改即可正常运行） 这是我在Startup.cs中添加到ConfigureServices函数的内容

public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

        // Create the Bot Framework Adapter.
        services.AddSingleton<IBotFrameworkHttpAdapter, AdapterWithErrorHandler>();

        //// Create the User state
        services.AddSingleton<UserState>();

        //// Create the Conversation State
        services.AddSingleton<ConversationState>();

        // Create the bot as a transient. In this case the ASP Controller is expecting an IBot.
        services.AddTransient<IBot, EchoBot>();
    }

public void配置服务（IServiceCollection服务）
{
services.AddMvc（）.SetCompatibilityVersion（CompatibilityVersion.Version_2_1）；
//创建Bot框架适配器。
services.AddSingleton（）；
////创建用户状态
services.AddSingleton（）；
////创建对话状态
services.AddSingleton（）；
//将bot创建为瞬态。在这种情况下，ASP控制器需要一个IBot。
services.AddTransient（）；
}

这是我添加到EchoBot.cs的内容

private readonly BotState _userState;
    private readonly BotState _conversationState;

    public EchoBot (ConversationState conversationState, UserState userState)
    {
        _conversationState = conversationState;
        _userState = userState;
    }

    protected override async Task OnMessageActivityAsync(ITurnContext<IMessageActivity> turnContext, CancellationToken cancellationToken)
    {
        var conversationStateAccessors = _conversationState.CreateProperty<ConversationFlow>(nameof(ConversationFlow));
        var flow = await conversationStateAccessors.GetAsync(turnContext, () => new ConversationFlow());
        var userStateAccessors = _userState.CreateProperty<UserProfile>("User");
        var profile = await userStateAccessors.GetAsync(turnContext, () => new UserProfile());

        await _conversationState.SaveChangesAsync(turnContext);
        await _userState.SaveChangesAsync(turnContext);
        await turnContext.SendActivityAsync(MessageFactory.Text($"Echo: {turnContext.Activity.Text}"), cancellationToken);
    }

private readonly BotState\u userState；
私有只读BotState\u会话状态；
公共EchoBot（会话状态会话状态，用户状态用户状态）
{
_会话状态=会话状态；
_userState=userState；
}
受保护的重写异步任务OnMessageActivityAsync（ITurnContext turnContext，CancellationToken CancellationToken）
{
var conversationStateAccessors=_conversationState.CreateProperty（nameof（ConversationFlow））；
var flow=await conversationStateAccessors.GetAsync（turnContext，（）=>new ConversationFlow（））；
var userStateAccessors=\u userState.CreateProperty（“用户”）；
var profile=await userStateAccessors.GetAsync（turnContext，（）=>newuserprofile（））；
wait_conversationState.SaveChangesAsync（turnContext）；
wait_userState.saveChangesSync（turnContext）；
等待turnContext.SendActivityAsync（MessageFactory.Text（$“Echo:{turnContext.Activity.Text}”）、cancellationToken；
}

我在emulator中遇到的错误是POST 500 directline.conversationUpdate，这是我从bot控制台收到的错误截图：

谢谢！如果需要任何澄清，我会尽力更新。

需要派生的，但根据显示的

ConfigureServices

显示，其中一个未注册到

IServiceCollection

这将在尝试解决异常消息所指示的

ConversationState

时导致异常

一个在线示例显示了以下内容

// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

    // Create the Bot Framework Adapter with error handling enabled.
    services.AddSingleton<IBotFrameworkHttpAdapter, AdapterWithErrorHandler>();

    // Create the storage we'll be using for User and Conversation state. (Memory is great for testing purposes.)
    services.AddSingleton<IStorage, MemoryStorage>();

    // Create the User state.
    services.AddSingleton<UserState>();

    // Create the Conversation state.
    services.AddSingleton<ConversationState>();

    // Create the bot as a transient. In this case the ASP Controller is expecting an IBot.
    services.AddTransient<IBot, StateManagementBot>();
}

参考

谢谢！我现在明白了：）@BrainMeme如果这解决了最初的问题

// Create the storage we'll be using for User and Conversation state. (Memory is great for testing purposes.)
services.AddSingleton<IStorage, MemoryStorage>();
