您只需要处理MessageReceivedAsync
方法顶部的退出条件
在对话框顶部,您可以添加如下内容
private static IEnumerable<string> cancelTerms = new[] { "Cancel", "Back", "B", "Abort" };
那么,这只是理解用户发送的消息是否与任何取消条款匹配的问题。在MessageReceivedAsync
方法中,执行以下操作:
public virtual async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> result)
{
var message = await result;
if (IsCancel(message.Text))
{
context.Done<string>(null);
}
// rest of the code of this method..
}
公共虚拟异步任务消息ReceivedAsync(IDialogContext上下文,IAwaitable结果)
{
var消息=等待结果;
if(IsCancel(message.Text))
{
context.Done(null);
}
//此方法的其余代码。。
}
您还可以更一般地创建一个类似于中所做的CancelableIDialog。任务是.NET的一部分,它们与机器人程序无关。请注意,取消等待远程服务响应的任务不会向该服务发送任何特定消息。它只是取消了等待。如果要通知Bot服务终止对话框,需要找到并调用适当的方法。请尝试“context.Done(null);”
public virtual async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> result)
{
var message = await result;
if (IsCancel(message.Text))
{
context.Done<string>(null);
}
// rest of the code of this method..
}
