使用JSON.NET返回的ActionResult [英] Using JSON.NET to return ActionResult

问题描述

我想写一个C＃方法，将序列化的模型，并返回一个JSON结果。这里是我的code：

 公众的ActionResult读（[DataSourceRequest] DataSourceRequest要求）
    {
        变种项= db.Words.Take（1）.ToList（）;
        JsonSerializerSettings jsSettings =新JsonSerializerSettings（）;
        jsSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
        VAR转换= JsonConvert.SerializeObject（项目，空，jsSettings）;
        返回JSON（换算，JsonRequestBehavior.AllowGet）;
    }
 

我得到了以下JSON结果时，我去字/读取Chrome浏览器：

<$p$p><$c$c>\"[{\\\"WordId\\\":1,\\\"Rank\\\":1,\\\"PartOfSpeech\\\":\\\"article\\\",\\\"Image\\\":\\\"Upload/29/1/Capture1.PNG\\\",\\\"FrequencyNumber\\\":\\\"22038615\\\",\\\"Article\\\":null,\\\"ClarificationText\\\":null,\\\"WordName\\\":\\\"the | article\\\",\\\"MasterId\\\":0,\\\"SoundFileUrl\\\":\\\"/UploadSound/7fd752a6-97ef-4a99-b324-a160295b8ac4/1/sixty_vocab_click_button.mp3\\\",\\\"LangId\\\":1,\\\"CatId\\\":null,\\\"IsActive\\\":false}

我觉得\\转义引号是当您双击序列化一个对象从其他问题时出现的问题：
<一href=\"http://stackoverflow.com/questions/22294473/wcf-json-output-is-getting-unwanted-quotes-backslashes-added\">WCF JSON输出是收到骚扰报价和放大器;反斜线添加

这肯定看起来像我双序列化我的对象，因为我第一次使用序列化和JSON.NET然后我的结果传递到JSON（）函数。我需要手动序列化，以避免referenceloops，但我觉得我需要查看一个ActionResult。

我如何在这里返回一个ActionResult？我是否需要，或者我只返回一个字符串？

解决方案

我发现了一个类似计算器的问题：
JSon.net而ActionResult的

答案有使用提示

 返回内容（改装后的应用/ JSON）;
 

这似乎是我最简单的网页上工作。

I'm trying to write a C# method that will serialize a model and return a JSON result. Here's my code:

    public ActionResult Read([DataSourceRequest] DataSourceRequest request)
    {
        var items = db.Words.Take(1).ToList();
        JsonSerializerSettings jsSettings = new JsonSerializerSettings();
        jsSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
        var converted = JsonConvert.SerializeObject(items, null, jsSettings);
        return Json(converted, JsonRequestBehavior.AllowGet);
    }

I got the following JSON result when I go to Words/Read in Chrome:

"[{\"WordId\":1,\"Rank\":1,\"PartOfSpeech\":\"article\",\"Image\":\"Upload/29/1/Capture1.PNG\",\"FrequencyNumber\":\"22038615\",\"Article\":null,\"ClarificationText\":null,\"WordName\":\"the | article\",\"MasterId\":0,\"SoundFileUrl\":\"/UploadSound/7fd752a6-97ef-4a99-b324-a160295b8ac4/1/sixty_vocab_click_button.mp3\",\"LangId\":1,\"CatId\":null,\"IsActive\":false}

I think the \" escaped quotes are a problem that occurs when you double serialize an object. From other questions: WCF JSON output is getting unwanted quotes & backslashes added

It definitely looks like I'm double serializing my object, since I first serialize using JSON.NET and then pass my result into the Json() function. I need to manually serialize to avoid referenceloops, but I think my View needs an ActionResult.

How can I return an ActionResult here? Do I need to, or can I just return a string?

解决方案

I found a similar stackoverflow question: JSon.net And ActionResult

The answer there suggested using

return Content( converted, "application/json" );

That seems to work on my very simple page.
