asp.net mvc json结果格式
public class JsonCategoriesDisplay
{
public JsonCategoriesDisplay() { }
public int CategoryID { set; get; }
public string CategoryTitle { set; get; }
}
public class ArticleCategoryRepository
{
private DB db = new DB();
public IQueryable<JsonCategoriesDisplay> JsonFindAllCategories()
{
var result = from c in db.ArticleCategories
select new JsonCategoriesDisplay
{
CategoryID = c.CategoryID,
CategoryTitle = c.Title
};
return result;
}
....
}
public class ArticleController : Controller
{
ArticleRepository articleRepository = new ArticleRepository();
ArticleCategoryRepository articleCategoryRepository = new ArticleCategoryRepository();
public string Categories()
{
var jsonCats = articleCategoryRepository.JsonFindAllCategories().ToList();
//return Json(jsonCats, JsonRequestBehavior.AllowGet);
return new JavaScriptSerializer().Serialize(new { jsonCats});
}
}
结果如下:
{"jsonCats":[{"CategoryID":2,"CategoryTitle":"Politika"},{"CategoryID":3,"CategoryTitle":"Informatika"},{"CategoryID":4,"CategoryTitle":"Nova
kategorija"},{"CategoryID":5,"CategoryTitle":"Testna
kategorija"}]}
如果我使用注释行并放置 JsonResult 而不是返回字符串,我会得到以下结果:<
[{"CategoryID":2,"CategoryTitle":"Politika"},{"CategoryID":3,"CategoryTitle":"Informatika"},{"CategoryID":4,"CategoryTitle":"Nova
kategorija"},{"CategoryID":5,"CategoryTitle":"Testna
kategorija"}]
但是,我需要将结果格式化为如下所示:
{'2':'Politika','3':'Informatika','4':'Nova
kateorija','5':'Testna kategorija'}
是否有一种简单的方法来完成此操作,或者我需要对结果进行硬编码?
public class JsonCategoriesDisplay
{
public JsonCategoriesDisplay() { }
public int CategoryID { set; get; }
public string CategoryTitle { set; get; }
}
public class ArticleCategoryRepository
{
private DB db = new DB();
public IQueryable<JsonCategoriesDisplay> JsonFindAllCategories()
{
var result = from c in db.ArticleCategories
select new JsonCategoriesDisplay
{
CategoryID = c.CategoryID,
CategoryTitle = c.Title
};
return result;
}
....
}
public class ArticleController : Controller
{
ArticleRepository articleRepository = new ArticleRepository();
ArticleCategoryRepository articleCategoryRepository = new ArticleCategoryRepository();
public string Categories()
{
var jsonCats = articleCategoryRepository.JsonFindAllCategories().ToList();
//return Json(jsonCats, JsonRequestBehavior.AllowGet);
return new JavaScriptSerializer().Serialize(new { jsonCats});
}
}
This results with following:
{"jsonCats":[{"CategoryID":2,"CategoryTitle":"Politika"},{"CategoryID":3,"CategoryTitle":"Informatika"},{"CategoryID":4,"CategoryTitle":"Nova
kategorija"},{"CategoryID":5,"CategoryTitle":"Testna
kategorija"}]}
If I use line that is commented and place JsonResult instead of returning string, I get following result:<
[{"CategoryID":2,"CategoryTitle":"Politika"},{"CategoryID":3,"CategoryTitle":"Informatika"},{"CategoryID":4,"CategoryTitle":"Nova
kategorija"},{"CategoryID":5,"CategoryTitle":"Testna
kategorija"}]
But, I need result to be formatted like this:
{'2':'Politika','3':'Informatika','4':'Nova
kateorija','5':'Testna kategorija'}
Is there a simple way to accomplish this or I will need to hardcode result?

查看 Json.Net 库
我已在 .net mvc 项目中成功使用它。
Have a look at the Json.Net library
I have successfully used it within a .net mvc project.
ile,
你真的应该看看 json.net lib,我最近在 json/jquery 和 mvc 方面遇到了类似的困境,并尝试了我自己的手卷版本,但在我自己的实现中遇到了许多限制。 newton json lib 非常简单 - 使用简单并且始终在更新。当前版本可以很好地处理嵌套结构,从而使特定的 json 格式问题不再是问题。
看一下,您需要 15 分钟才能掌握。
ile,
you really should look at the json.net lib, i was in a similar dilemma recently with json/jquery and mvc and tried my own hand-rolled version but hit the many limitations in my own implemetation. the newton json lib is quite simply a no-brainer - simple to use and always being updated. the current version works fantastically with nested structures, thus making that particular json formatting issue a non-issue.
give it a look, will take you 15 mins to get to grips with.
尝试将其作为数组返回,另外,如果您返回 JsonResult 您可以节省大量代码(看起来您正在尝试获取所需的格式),
在我的测试中我得到了结果
Try returning it as an Array, Also if you return a JsonResult you can save alot of code (looks like you were attempting to get the formatting you wanted)
in my test I got a result of
