将两个参数传递给控制器​​方法 [英] Pass two parameters to controller method

问题描述

我的默认路线是

My default route is

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Account", action = "Login", id = UrlParameter.Optional }
);

现在在控制器中，我有方法。

Now in the controller, I have the method.

public ActionResult LanguageEdit(int id)
       {

视图中的相应代码为：

The corresponding code in the view is:

<div class="widget-content">
                       @using (Html.BeginForm("Language", "Country", FormMethod.Post, new { enctype = "multipart/form-data" }))
                       {
                           @Html.HiddenFor(m => m.CountryId)
                           @Html.Grid(Model.Languages).Columns(column =>
                      {
                          column.For(m => m.LanguageName).Named("Languages");
                          column.For(m => String.Format("<a class='btn btn-primary' href='/Country/LanguageEdit/{0}'>Edit</a> <a href='#deleteConfirmModal' role='button' data-toggle='modal' class='btn btn-danger deleteBtn'><input type='hidden' id='countryId' value='{0}'/>Remove</a>", m.CountryId)).Named("Actions").Encode(false);
                      }).Attributes(@class => "table")
                       }
                   </div>

我们将id（CountryId）传递给方法。

但是出于某种原因，我必须将另一个参数languageId传递给控制器方法。



那么最好的方法是什么？



我试过的：



尝试这个，但仍然不清楚。需要代码帮助。特别是在视图中。

We pass id (CountryId) to the method.
However for some reason, I have to pass another parameter languageId to the controller method.

So what is the best way?

What I have tried:

tried this, but still not clear. Need code assistance. Specifically in the view.

推荐答案

在我看来，传递参数集合的简单方法是创建一个类，其中包含与参数一样多的属性。

例如：

In my opinion the simple way for passing a collection of parameters is create a class that has as many properties as "parameters" do you want.
For example:

public class model1
{
	public int param1;
	public int param2;
	...       
}

然后你的控制器应声明为：

And then your controller should be declared as:

public ActionResult LanguageEdit(model1 model)
{
	...
		model1.param1
		...
		model2.param2
	...
}

在视图中如下：

And inthe view something like:

@Html.HiddenFor(m => m.param1)
    ...
@Html.TextFor(m => m.param2)

这种类可以扩展到任意类型（或类型）的任何数量的参数

This kind of "class" can be extended to any number of "parameters" of any kind (or type)

抱歉，我没有意识到您没有提交表单，而是提示点击链接。你需要做这样的事情

Sorry I didn't realise you were not submitting the form but rendering a link to click. You'll need to do something like this

column.For(m => String.Format("<a class='btn btn-primary' href='/Country/LanguageEdit/{0}?LanguageId={1}'>Edit</a> <a href='#deleteConfirmModal' role='button' data-toggle='modal' class='btn btn-danger deleteBtn'><input type='hidden' id='countryId' value='{0}'/>Remove</a>", m.CountryId, m.LanguageId)).Named("Actions").Encode(false);

然后改变你的控制器动作

Then change your controller action

public ActionResult LanguageEdit(int id, int? languageId)
        {

id将通过路由填充，而languageId通过标准查询字符串值填充

"id" will be populated via routing, and languageId populated via standard querystring values
