用户回答“否”时如何重定向到另一个页面

Question

选择的答案是保留选项“是”和“否”的变量，因此，当用户在单选按钮上选择“否”时，它必须退出并加载另一页

        [HttpPost]
        public ActionResult Index(Evaluation answer)
        {
        using (QuestionMangerDBDataContext data = new QuestionMangerDBDataContext())
        {

            if (ModelState.IsValid)
            {

                var selectedAnswer = answer.selectedAnwser;
                var qId = answer.questionId;

                 // Save the data 
                QuestionMangerDATA.questionManagerAnswer tmpQAA = new QuestionMangerDATA.questionManagerAnswer();
                tmpQAA.QuestionID = qId;
                tmpQAA.QuestionAnswerID = int.Parse(selectedAnswer);
                tmpQAA.UserId = 4;
                tmpQAA.AnswerValue = "WHAT IS THIS?!";
                if (selectedAnswer == "NO")
                {
                    tmpQAA.QuestionID = qId;
                }

                data.questionManagerAnswers.InsertOnSubmit(tmpQAA);
                data.SubmitChanges();

            }

好吧，奇怪的示例，因为您的ActionResult ...现在不返回任何内容。

您可以使用if else进行重定向，例如，可以将其表示为

return selectedAnswer == "NO" 
          ? RedirectToAction("someAction")
          : RedirectToAction("someOtherAction")

或如果您不想执行部分代码（如果selectedAnswer == "NO"

if (selectedAnswer=="No") 
   return RedirectToAction("someAction");

//this part won't be executed if selectedanswer == "No"
data.questionManagerAnswers.InsertOnSubmit(tmpQAA);
data.SubmitChanges();
return RedirectToAction("someOtherAction");
