Matt's should work fine. If you are still passing in FormMethod.Post, though, you need to do it like this:
马特的应该工作正常。FormMethod.Post但是，如果您仍然传入，则需要这样做：
Html.BeginForm("action","controller", new { Id = 12345 }, FormMethod.Post);
Reversing the third and fourth parameters will result in the Idbeing treated as an attribute instead of a route value.
反转第三个和第四个参数将导致将Id其视为属性而不是路由值。

Html.BeginForm("action", "controller", new {Id = 12345})
Html.BeginForm("action", "controller", new {Id = 12345})

Html.BeginForm("action", "controller", new { id = ViewBag.FileID },
FormMethod.Post, new { id = "feedbackform" })
As for the querystring, ?type=golden, I don't know how to do that. Of course, a querysting is a get, and undermines the whole purpose of FormMethod.Post. I mean, you could use FormMethod.Get, if you want querystring data, and this might be what you are looking for.
至于查询字符串，?type=golden我不知道该怎么做。当然，查询语句是获取，并且破坏了FormMethod.Post. 我的意思是，FormMethod.Get如果你想要查询字符串数据，你可以使用, 这可能就是你正在寻找的。
Additionally, you can avoid html.beginformand do the querystring, get + post, manually with a form tag.
此外，您可以html.beginform使用表单标签手动避免和执行查询字符串、获取 + 发布。
Thirdly, if you are using the form, you can make a hidden field:
第三，如果你使用表单，你可以做一个隐藏字段：
[input type=hidden name="type" value="golden"]
Then, when the submit button is pressed the value is passed properly as a form variable.
然后，当按下提交按钮时，该值作为表单变量正确传递。
