Rendering partial views with Razor in MVC5
提问by Mourndark
I'm trying to get a partial view to render using Razor in MVC5. When I use
我正在尝试在 MVC5 中使用 Razor 获得局部视图以进行渲染。当我使用
@{ Html.RenderPartial("ViewName", model); }
I get the parser error:
我收到解析器错误：
Unexpected "{" after "@" character. Once inside the body of a code block (@if {}, @{}, etc.) you do not need to use "@{" to switch to code.
“@”字符后出现意外的“{”。一旦进入代码块的主体（@if {}、@{} 等），您就不需要使用“@{”来切换到代码。
When I remove the {}, i.e.:
当我删除{}，即：
@Html.RenderPartial("ViewName", model);
I get the compilation error
我收到编译错误
Cannot implicitly convert type 'void' to 'object'.
无法将类型“void”隐式转换为“object”。
What am I doing wrong?
我究竟做错了什么？

You haven't posted the context of that code, but that error only really happens when you're using @directly within a code block without any HTML wrappings. For example:
您还没有发布该代码的上下文，但只有当您@直接在没有任何 HTML 包装的代码块中使用时，才会真正发生该错误。例如：
@if (true) {
@{ Html.RenderPartial(...); }
}
Would give you the error, while:
会给你错误，而：
@if (true) {
<div>
@{ Html.RenderPartial(...); }
</div>
}
Would be fine. You could also solve it by just removing the code block for Html.RenderPartialentirely, including the @:
会好的。您也可以通过完全删除代码块来解决它Html.RenderPartial，包括@：
@if (true) {
Html.RenderPartial(...);
}

You may also use @Html.Partial("~/View/Home/myview.cshtml")
你也可以使用 @Html.Partial("~/View/Home/myview.cshtml")
It returns string while Html.RenderPartialcalls Write internally, and returns void.
它在Html.RenderPartial内部调用 Write 时返回字符串，并返回 void。

This is wrong:
这是错误的：
@Html.RenderPartial("ViewName", model);
This is correct:
这是对的：
@{ Html.RenderPartial("ViewName", model); }
The parsing error might be caused by the partial view's content. For example, if you have an email address, make sure you use @@ to properly escape the @ sign.
解析错误可能是由部分视图的内容引起的。例如，如果您有电子邮件地址，请确保使用 @@ 正确转义 @ 符号。
Unexpected "{" after "@" character. Once inside the body of a code block (@if {}, @{}, etc.) you do not need to use "@{" to switch to code.
“@”字符后出现意外的“{”。一旦进入代码块的主体（@if {}、@{} 等），您就不需要使用“@{”来切换到代码。

can you show the code surrounding your RenderPartial? I'm guessing you're in a loop, if block, or some other type of code block. If so, you would just call
你能显示围绕你的 RenderPartial 的代码吗？我猜你在循环、if 块或其他类型的代码块中。如果是这样，您只需致电
Html.RenderPartial("ViewName", model);

Please review your code, you might be getting that error because you are using this code:
@{ Html.RenderPartial("ViewName", model); }inside any other @{}clause. Please, read again carefully the error message you get in the browser, you don't need to use the @{}to switch to code because you already are inside, so, just remove @{and }and you should getting it working properly.
请检查您的代码，您可能会收到该错误，因为您正在使用此代码：
@{ Html.RenderPartial("ViewName", model); }在任何其他@{}子句中。请再次仔细阅读您在浏览器中得到错误信息，你不需要使用@{}到切换到代码，因为你已经在里面，所以，只是删除@{和}，你应该得到它正常工作。

Use @Html.Partial(). It has three overloads, pass the parameters as per your requirement.
使用@Html.Partial(). 它有三个重载，根据您的要求传递参数。
