Using Html.BeginForm with querystring
提问by Tae-Sung Shin
My url looks like this:
我的网址如下所示：
customer/login?ReturnUrl=home
In the login view, I have used this pattern of code which works fine.
在登录视图中，我使用了这种工作正常的代码模式。
@using(Html.BeginForm())
{
...
}
This magically generates following html
这神奇地生成了以下 html
<form action="customer/login?ReturnUrl=home" method="post">
But now, I need to add an attribute (e.g., data-id="something") in the form. How can I do that? If I don't have any query string, I know I can do something like this:
但是现在，我需要data-id="something"在表单中添加一个属性（例如，）。我怎样才能做到这一点？如果我没有任何查询字符串，我知道我可以这样做：
@using(Html.BeginForm(action, controller, FormMethod.Post,
new { data_id="something" }))
But don't know how to add querystring which should be in html:
但不知道如何添加应该在 html 中的查询字符串：
<form action="customer/login?ReturnUrl=home" method="post" data-id="something">
I thought about using <form>directly but don't know how to specify querystring which is variable. And I have no idea how to achieve it with Html.BeginForm. Any tip would be appreciated.
我想<form>直接使用但不知道如何指定可变的查询字符串。而且我不知道如何使用Html.BeginForm. 任何提示将不胜感激。
RESOLUTION:
解析度：
For now, I used <form>with following hint How to get current url value in View. The resulting view looks like
现在，我使用<form>了以下提示How to get current url value in View。结果视图看起来像
<form action="@Request.Url.PathAndQuery" data-id="something" method="POST">
But it would be nice to have an overloaded method of BeginFormfor this.
但是如果有一个重载的方法会很好BeginForm。

I guess this doesn't directly answer the question, but why not just use a plain old form tag?
我想这并没有直接回答这个问题，但为什么不直接使用一个普通的旧表单标签呢？
<form action='customer/[email protected]["ReturnUrl"]' method="post" data-id="something">
Alternatively, you can create a custom HtmlHelperExtension that renders a form with path and querystring. In this HtmlHelperExtension you can iterate through your querystring values and populate the routeValueDictionary which you then pass to a Html.BeginForm constructor.
或者，您可以创建一个自定义 HtmlHelperExtension 来呈现带有路径和查询字符串的表单。在此 HtmlHelperExtension 中，您可以遍历查询字符串值并填充 routeValueDictionary，然后将其传递给 Html.BeginForm 构造函数。
If you don't want something so extensible you can just use the overloaded constructor of Html.BeginForm using
@Html.BeginForm("login", "customer", new {ReturnUrl = @Request.QueryString["ReturnUrl"]},FormMethod.Post, new {data-id="something"});
如果你不想要如此可扩展的东西，你可以使用 Html.BeginForm 的重载构造函数
@Html.BeginForm("login", "customer", new {ReturnUrl = @Request.QueryString["ReturnUrl"]},FormMethod.Post, new {data-id="something"});

Here's The way that worked for me
这是对我有用的方法
Html.BeginForm("Profile", "Partner", routeValues: new {id=Partner.partner_id},method:FormMethod.Post)
It was almost like there was a problem with overloading the method, but by specifying what things are, it seems to work fine...
这几乎就像重载方法有问题，但是通过指定内容，它似乎工作正常......

To create a RouteValueDictionary from the querystring:
要从查询字符串创建 RouteValueDictionary：
RouteValueDictionary queryStringDictionary = new RouteValueDictionary(Request.QueryString.AllKeys.ToDictionary(key => key, key => (object)Request.QueryString[key]));
Then you can use it with Html.BeginForm:
然后你可以将它与 Html.BeginForm 一起使用：
Html.BeginForm(null, null, queryStringDictionary, FormMethod.Post, new Dictionary<string, object> { { "autocomplete", "off" } })

using Reflector to look at the code,
使用 Reflector 查看代码，
BeginForm() will pass directly the rawUrl over to the final Form. Any other overloads on BeginForm will go through a helper utility which will strip the query string.
BeginForm() 将直接将 rawUrl 传递给最终的 Form。BeginForm 上的任何其他重载都将通过一个帮助程序实用程序，该实用程序将删除查询字符串。

This works for me :
这对我有用：
@using (Html.BeginForm("index", "Photos", routeValues: new { user = pUser, album = pAlbum, }, method: FormMethod.Get))
Explicit route values and method is what is required...
需要显式路由值和方法...

Just incase you wanted to add other attributes as well. use below code
以防万一您还想添加其他属性。使用下面的代码
@using (Html.BeginForm("actionName", "controllerName", routeValues: new { lang = "en" }, method:FormMethod.Post, htmlAttributes: new { @class= "my-form", enctype = "multipart/form-data" }))
回答by Michael Sagalovich
Try @using(Html.BeginForm(null, null, FormMethod.Post, new { data_id="something" }))
尝试 @using(Html.BeginForm(null, null, FormMethod.Post, new { data_id="something" }))
It should use the default logic to construct the url, just as if you used BeginForm()
它应该使用默认逻辑来构造 url，就像你使用 BeginForm()
(never tried that though in such case, but I believe it should work)
（虽然在这种情况下从未尝试过，但我相信它应该有效）
