【问题描述】：

下面是整个代码块，基本上是表单流，我正在尝试将数据保存到 botState。

public class ProfileForm

    // these are the fields that will hold the data
    // we will gather with the form
    [Prompt("What is your first name? ||")]
    public string FirstName;

    [Prompt("What is your last name? ||")]
    public string LastName;

    [Prompt("What is your gender? ||")]
    public Gender Gender;

    // This method 'builds' the form 
    // This method will be called by code we will place
    // in the MakeRootDialog method of the MessagesControlller.cs file

    public static IForm<ProfileForm> BuildForm()
    
        return new FormBuilder<ProfileForm>()

                .Message("Please complete your profile!")
                .OnCompletion(async (context, profileForm) =>

                
                    BotData bt = new BotData();

                    await context.PostAsync("Your profile is complete.\n\n"+profileForm.FirstName+profileForm.LastName+profileForm.Gender);

                    SessionInfo.botUserData.SetProperty<bool>("ProfileComplete", true);
                    SessionInfo.botUserData.SetProperty<string>("FirstName", profileForm.FirstName);
                    SessionInfo.botUserData.SetProperty<string>("LastName", profileForm.LastName);
                    SessionInfo.botUserData.SetProperty<string>("Gender", profileForm.Gender==Gender.Male? "Male" :"Female");

                    await context.PostAsync("Before Saving");

                    await SessionInfo.userStateClient.BotState.SetPrivateConversationDataWithHttpMessagesAsync(
                        SessionInfo.ChannelID, SessionInfo.ConversationID, SessionInfo.FromID, SessionInfo.botUserData);
                    // Tell the user that the form is complete
                    await context.PostAsync("Your profile is complete.");

                )
                .Build();
    

// This enum provides the possible values for the 
// Gender property in the ProfileForm class
// Notice we start the options at 1 
[Serializable]

public enum Gender



    Male = 1, Female = 2

;

我在SetPrivateConversationDataWithHttpMessagesAsync() 方法调用行遇到以下错误，请帮助。

【问题讨论】：

如果您不发布所涉及的整个代码，真的很难知道这里发生了什么。

我已经更新了整个代码块，基本上它在表单流中，我正在尝试将数据保存为机器人状态。更详细地说，我正在使用来自 Facebook Messenger 的代码。

【参考方案1】：

这个问题有点难以理解，但我想提一下，botUserData.SetProperty<>() 函数不保存属性，它只是编辑当前对象的属性。您应该使用 BotState.SetUserData() 并将对象传递给他以保存它。 这是一个保存机器人状态的工作示例：

public static bool saveData(Activity activity, string key, string value)

    StateClient stateClient = activity.GetStateClient();
    BotData userData = stateClient.BotState.GetUserData(activity.ChannelId, activity.From.Id);
    userData.SetProperty<string>(key, value);
    BotData updateResponse = stateClient.BotState.SetUserData(activity.ChannelId, activity.From.Id, userData);
    return value == updateResponse.GetProperty<string>(key);
