Answer 1

嗯，奇怪的样本，因为你的ActionResult ...现在没有返回任何内容。

您可以使用if else进行重定向，例如，可以表示为

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

或如果您不希望执行selectedAnswer == "NO"

的部分代码

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

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