Could you just instantiate the controller in your action method and call the other method you need?

<pre><code>public ActionResult YourActionMethod()
{
 SomeController c = new SomeController();
 ActionResult result = c.SomeMethod();

 return View();
}
</code></pre>

blocks|key|1474437|text|看起来你在尝试做一些控制器没有设计好的事情。将所需的方法设计为某个类中的公共方法，并从两个控制器操作中调用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1474438|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Looks like you're trying to do something the controllers aren't designed for.
Design your required method as an public method in some class and invoke from both controller actions.

blocks|key|1474483|text|我听起来好像你应该重构你的应用程序，并将生成字符串的功能提取到一个新的独立类中(或者重用一个现有的类，如果你有一个合适的类)，并让两个控制器都使用那个类。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1474484|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Sounds in my ears like you should refactor your application, and extract the functionality that generates the string out to a new seperate class (or reuse an existing class, if you have one that fits) and let both controllers use that class.

You can achieve this via the <a href="http://msdn.microsoft.com/en-us/library/system.web.mvc.html.childactionextensions.action.aspx" rel="noreferrer"><code>Action</code></a> method of <code>HtmlHelper</code>.

In a view, you would do it like this:

<pre><code>@Html.Action("OtherAction")
</code></pre>

However it's not straightforward to obtain an instance of <code>HtmlHelper</code> in an action method (by design). In fact it's such a horrible hack that I am reluctant to even post it...

<pre><code>var htmlHelper = new HtmlHelper(new ViewContext(
 ControllerContext, 
 new WebFormView(ControllerContext, "HACK"),
 new ViewDataDictionary(),
 new TempDataDictionary(),
 new StringWriter()),
 new ViewPage());

var otherViewHtml = htmlHelper.Action("ActionName", "ControllerName");
</code></pre>

This works on MVC 3. You might need to remove the <code>StringWriter</code> arg from the <code>ViewContext</code> constructor for MVC 2, IIRC.

&lt;/hack>

I was looking for the same thing, but seriously people, why the need to write such complicated answers.

Here's a post that will answer it very simply:
<a href="https://stackoverflow.com/questions/776781/using-html-actionlink-to-call-action-on-different-controller">Using Html.ActionLink to call action on different controller</a>

Basically you just have to use this overload of the actionlink:
<code>ActionLink(HtmlHelper, String, String, String, Object, Object)</code>

So you will have:
<code>ActionLink("linkText", "actionName", "controllerName", routeValues, htmlAttributes)</code>

If you don't have any routeValues (which are the Inputs for the Action) or htmlAttributes, you have to set them as null.

Here's an example call:
<code>@Html.ActionLink("Add New Student", "Create", "Student", null, new { @class = "btn btn-primary" })</code>

blocks|key|1474698|text|您可以使用以下方法调用另一个控制器上的方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1474699|var+otherController+=+DependencyResolver.Current.GetService<OtherController>();
var+result+=+otherController.SomeMethod();|code-block|syntax|javascript|1474700|在ASP.NET+MVC5中，这对我很有效。希望它也能为你工作。|1474701|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

You can use the following approach to invoke a method on the other controller:

<pre><code>var otherController = DependencyResolver.Current.GetService&lt;OtherController&gt;();
var result = otherController.SomeMethod();
</code></pre>

This worked for me in ASP.NET MVC5. Hope that it will work for you as well.

Can anybody tell me how to call a method on a different controller from within an action method? I don't want to redirect. I want to call a method on a different controller that returns a string and use the response within my action method.

.NET MVC Call method on different controller

有人能告诉我如何在action方法中调用不同控制器上的方法吗？我不想重定向。我想在另一个控制器上调用一个返回字符串的方法，并在我的action方法中使用响应。
