Question

下面是整个代码块，基本上是表单流，我尝试将数据保存到botState中。

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

};

我在行SetPrivateConversationDataWithHttpMessagesAsync()方法调用时遇到以下错误，请帮忙。

对象引用未设置为对象的实例。

有点难以理解这个问题，但我想提一下，函数botUserData.SetProperty<>()没有保存属性，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以下是保存bot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);
}

MS BotFramework数据保存，BotState
