blocks|key|890868|text|我刚刚找到了答案，似乎我放置RenderPartial代码的视图有一个动态模型，因此，MVC无法选择正确的方法。将RenderPartial调用中的模型强制转换为正确的类型修复了此问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|890869|来源：Using+Html.RenderPartial()+in+ascx+files|offset|length|890870|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/questions/3822546^0|0|3|14|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

Just found the answer, it appears that the view where I was placing the RenderPartial code had a dynamic model, and thus, MVC couldn't choose the correct method to use. Casting the model in the RenderPartial call to the correct type fixed the issue.

blocks|key|890963|text|与在RenderPartial调用中强制转换模型不同，由于您使用的是razor，因此可以从|type|unstyled|depth|inlineStyleRanges|entityRanges|data|890964|@model+dynamic|code-block|syntax|javascript|890965|至|890966|@model+YourNamespace.YourModelType|890967|这样做的好处是可以处理视图中的每个@Html.Partial调用，还可以为您提供属性的智能感知。|offset|length|style|CODE|890968|entityMap^0|0|0|0|0|H|D|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|U|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|W|8|@$M|X|N|Y|O|P]]|9|@]|A|$]]|$1|Q|3|-4|5|6|7|Z|8|@]|9|@]|A|$]]]|R|$]]

Instead of casting the model in the RenderPartial call, and since you're using razor, you can modify the first line in your view from

<pre><code>@model dynamic
</code></pre>

to

<pre><code>@model YourNamespace.YourModelType
</code></pre>

This has the advantage of working on every <code>@Html.Partial</code> call you have in the view, and also gives you intellisense for the properties.

blocks|key|1105827|text|也可以被调用为|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1105828|@Html.Partial("_PartialView",+(ModelClass)View.Data)|code-block|syntax|javascript|1105829|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Can also be called as

<pre><code>@Html.Partial("_PartialView", (ModelClass)View.Data)
</code></pre>

blocks|key|891039|text|即使你没有使用dynamic/ExpandoObject，也会抛出这个问题的另一个原因。如果您正在执行循环，则如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|891040|@foreach+(var+folder+in+ViewBag.RootFolder.ChildFolders.ToList())
{
++++@Html.Partial("ContentFolderTreeViewItems",+folder)
}|code-block|syntax|javascript|891041|在这种情况下，"+var“而不是类型声明将抛出相同的错误，尽管RootFolder的类型是”文件夹“。通过将var更改为实际类型，问题就会消失。|891042|@foreach+(ContentFolder+folder+in+ViewBag.RootFolder.ChildFolders.ToList())
{
++++@Html.Partial("ContentFolderTreeViewItems",+folder)
}|891043|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

There's another reason that this can be thrown, even if you're not using dynamic/ExpandoObject. If you are doing a loop, like this:

<pre><code>@foreach (var folder in ViewBag.RootFolder.ChildFolders.ToList())
{
 @Html.Partial("ContentFolderTreeViewItems", folder)
}
</code></pre>

In that case, the "var" instead of the type declaration will throw the same error, despite the fact that RootFolder is of type "Folder. By changing the var to the actual type, the problem goes away.

<pre><code>@foreach (ContentFolder folder in ViewBag.RootFolder.ChildFolders.ToList())
{
 @Html.Partial("ContentFolderTreeViewItems", folder)
}
</code></pre>

Here's a way to pass a dynamic object to a view (or partial view)

Add the following class anywhere in your solution (use System namespace, so its ready to use without having to add any references) - 

<pre><code> namespace System
 {
 public static class ExpandoHelper
 {
 public static ExpandoObject ToExpando(this object anonymousObject)
 {
 IDictionary&lt;string, object&gt; anonymousDictionary = HtmlHelper.AnonymousObjectToHtmlAttributes(anonymousObject);
 IDictionary&lt;string, object&gt; expando = new ExpandoObject();
 foreach (var item in anonymousDictionary)
 expando.Add(item);
 return (ExpandoObject)expando;
 }

 }
 }
</code></pre>

When you send the model to the view, convert it to Expando : 

<pre><code> return View(new {x=4, y=6}.ToExpando());
</code></pre>

Cheers

blocks|key|1105967|text|我也遇到了同样的问题&在我的例子中，我是这样做的|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1105968|@Html.Partial("~/Views/Cabinets/_List.cshtml",+(List<Shop>)ViewBag.cabinets)|code-block|syntax|javascript|1105969|在局部视图中|1105970|@foreach+(Shop+cabinet+in+Model)

I had the same problem &amp; in my case this is what I did

<pre><code>@Html.Partial("~/Views/Cabinets/_List.cshtml", (List&lt;Shop&gt;)ViewBag.cabinets)

I was playing around with C# code an I accidentally found the solution to your problem haha

This is the code for the Principal view:

<pre><code>`@model dynamic 
 @Html.Partial("_Partial", Model as IDictionary&lt;string, object&gt;)`
</code></pre>

Then in the Partial view:

<pre><code>`@model dynamic 
 @if (Model != null) { 
 foreach (var item in Model) 
 { 
 &lt;div&gt;@item.text&lt;/div&gt; 
 } 
 }`
</code></pre>

It worked for me, I hope this will help you too!!

When I try to render a partial view whose model type is specified as:

<pre><code>@model dynamic
</code></pre>

by using the following code:

<pre><code>@{Html.RenderPartial("PartialView", Model.UserProfile);}
</code></pre>

I get the following exception:

<pre><code>'System.Web.Mvc.HtmlHelper&lt;dynamic&gt;' has no applicable method named 'RenderPartial' but appears to have an extension method by that name. Extension methods cannot be dynamically dispatched. Consider casting the dynamic arguments or calling the extension method without the extension method syntax.
</code></pre>

However, the same code in a .aspx file works flawlessly. Any thoughts?
