How to determine if the view is for GET or POST in ASP.NET MVC?
提问by FreeVice
MVC use action attributes to map the same view for http get or post:
MVC 使用 action 属性为 http get 或 post 映射相同的视图：
[HttpGet]
public ActionResult Index()
{
ViewBag.Message = "Message";
return View();
}
[HttpPost]
public ActionResult Index(decimal a, decimal b, string operation)
{
ViewBag.Message = "Calculation Result:";
ViewBag.Result = Calculation.Execute(a, b, operation);
return View();
}
In the MVC view, how can I determine if the view is for http get or http post?
在 MVC 视图中，如何确定该视图是用于 http get 还是 http post？
in Views it is IsPost
在视图中它是 IsPost
@{
var Message="";
if(IsPost)
{
Message ="This is from the postback";
}
else
{
Message="This is without postback";
}
}
PS: For dot net core it is:

System.Web.HttpContext.Current.Request.HttpMethodstores current method. Or just Request.HttpMethodinside of view, but if you need to check this, there may be something wrong with your approach.
System.Web.HttpContext.Current.Request.HttpMethod存储当前方法。或者只是Request.HttpMethod在视图内部，但如果您需要检查这一点，则您的方法可能有问题。
Think about using Post-Redirect-Get pattern to form reposting.
考虑使用 Post-Redirect-Get 模式来形成重新发布。

<% if (System.Web.HttpContext.Current.Request.HttpMethod.ToString() == "GET") { %><!-- This is GET --><% }
else if (System.Web.HttpContext.Current.Request.HttpMethod.ToString() == "POST")
{ %><!--This is POST--><%}
else
{ %><!--Something another --><% } %
