从MVC行动C＃类反序列化JSON字符串 [英] Deserialize Json string from MVC action to C# Class
问题描述
我有一个Ajax调用（对于HighChartsDB图）在Web窗体应用程序调用Web服务，它使用的WebRequest 来调用它返回另一个应用程序的MVC行动一个JsonResult。
我设法将数据传回给ajax调用，但我取回的数据不会被解析为JSON对象，但只是一个字符串。
我的类：
公共类CategoryDataViewModel
{
公共字符串名称{;组; }
公开名单＆LT; INT＆GT;数据{获得;组; }
公共双pointStart {获得;组; }
公众诠释pointInterval {{返回86400000; }}
}
我所谓的highcharts AJAX功能：
函数getBugs（mileId）{
VAR的结果;
$阿贾克斯（{
键入：GET，
网址：服务/ WebService.svc /的GetData'，
的contentType：应用/ JSON的;字符集= UTF-8，
异步：假的，
数据：{mileId形式：parseInt（mileId）}，
数据类型：JSON，
成功：功能（数据）{
的console.log（数据）;
结果=数据;
}
}）;
返回结果;
}
最后我的WebService
公共类的WebService：IWebService
{
公共字符串的GetData（INT mileId）
{
字符串的URL =HTTP：//本地主机：63418 /首页/ GetWoWData mileId =+ mileId;
WebRequest的WR = WebRequest.Create（URL）;
使用（VAR响应=（HttpWebResponse）wr.GetResponse（））
{
使用（VAR读卡器=新的StreamReader（response.GetResponseStream（）））
{
变种objText = reader.ReadToEnd（）;
返回objText;
}
}
}
}
通过这个当我CONSOLE.LOG在Ajax调用我得到的（数据）：
<$p$p><$c$c>[{\"name\":\"Sedan\",\"data\":[30,30,30,30,35],\"pointStart\":1307836800000,\"pointInterval\":86400000},{\"name\":\"Low\",\"data\":[800,800,800,826,1694],\"pointStart\":1307836800000,\"pointInterval\":86400000},{\"name\":\"Medium\",\"data\":[180,180,180,186,317],\"pointStart\":1307836800000,\"pointInterval\":86400000},{\"name\":\"High\",\"data\":[29,29,29,34,73],\"pointStart\":1307836800000,\"pointInterval\":86400000},{\"name\":\"Truck\",\"data\":[6,6,6,6,13],\"pointStart\":1307836800000,\"pointInterval\":86400000},{\"name\":\"SUV\",\"data\":[-172,-172,-172,-179,-239],\"pointStart\":1307836800000,\"pointInterval\":86400000},{\"name\":\"Convertible\",\"data\":[0,0,0,0,-404],\"pointStart\":1307836800000,\"pointInterval\":86400000},{\"name\":\"Limo\",\"data\":[-7,-7,-7,-8,-214],\"pointStart\":1307836800000,\"pointInterval\":86400000}]
我似乎无法管理传回一个合适的JSON对象。我试图将其转换回我CategoryDataViewModel这个在我的web服务：
VAR myojb =新CategoryDataViewModel（）;
使用（VAR响应=（HttpWebResponse）wr.GetResponse（））
{
使用（VAR读卡器=新的StreamReader（响应.GetResponseStream（）））
{
JavaScriptSerializer JS =新JavaScriptSerializer（）;
变种objText = reader.ReadToEnd（）;
myojb =（CategoryDataViewModel）js.Deserialize（objText的typeof（CategoryDataViewModel））;
}
}
返回myojb;
但后来我得到键入Test.CategoryDataViewModel不支持数组的反序列化。
修改
myojb =（CategoryDataViewModel）js.Deserialize（objText的typeof（CategoryDataViewModel））;
到
myojb =（名单＆LT; CategoryDataViewModel＆GT;）js.Deserialize（objText的typeof（名单＆LT; CategoryDataViewModel＆GT;））;
和你应该罚款。该阵列将反序列化到一个列表中没有任何问题。
I have an Ajax call (for a HighChartsDB chart) in a WebForm application that calls a webservice, which uses a WebRequest to call an MVC action in another application which returns a JsonResult.
I manage to pass the data back to the ajax call but the data I get back is not parsed as a json object but just a string.
My class:
public class CategoryDataViewModel
{
public string name { get; set; }
public List<int> data { get; set; }
public double pointStart { get; set; }
public int pointInterval { get { return 86400000; } }
}
My ajax function called by the highcharts:
function getBugs(mileId) {
var results;
$.ajax({
type: 'GET',
url: 'Services/WebService.svc/GetData',
contentType: "application/json; charset=utf-8",
async: false,
data: { "mileId": parseInt(mileId) },
dataType: "json",
success: function (data) {
console.log(data);
results = data;
}
});
return results;
}
And finally my WebService
public class WebService : IWebService
{
public string GetData(int mileId)
{
string url = "http://localhost:63418/Home/GetWoWData?mileId=" + mileId;
WebRequest wr = WebRequest.Create(url);
using (var response= (HttpWebResponse)wr.GetResponse())
{
using (var reader = new StreamReader(response.GetResponseStream()))
{
var objText = reader.ReadToEnd();
return objText;
}
}
}
}
With this when I console.log(data) on the ajax call I get:
[{\"name\":\"Sedan\",\"data\":[30,30,30,30,35],\"pointStart\":1307836800000,\"pointInterval\":86400000},{\"name\":\"Low\",\"data\":[800,800,800,826,1694],\"pointStart\":1307836800000,\"pointInterval\":86400000},{\"name\":\"Medium\",\"data\":[180,180,180,186,317],\"pointStart\":1307836800000,\"pointInterval\":86400000},{\"name\":\"High\",\"data\":[29,29,29,34,73],\"pointStart\":1307836800000,\"pointInterval\":86400000},{\"name\":\"Truck\",\"data\":[6,6,6,6,13],\"pointStart\":1307836800000,\"pointInterval\":86400000},{\"name\":\"SUV\",\"data\":[-172,-172,-172,-179,-239],\"pointStart\":1307836800000,\"pointInterval\":86400000},{\"name\":\"Convertible\",\"data\":[0,0,0,0,-404],\"pointStart\":1307836800000,\"pointInterval\":86400000},{\"name\":\"Limo\",\"data\":[-7,-7,-7,-8,-214],\"pointStart\":1307836800000,\"pointInterval\":86400000}]
I can't seem to manage to pass back into a proper Json object. I tried converting it back to my CategoryDataViewModel with this in my webservice:
var myojb = new CategoryDataViewModel ();
using (var response = (HttpWebResponse)wr.GetResponse())
{
using (var reader = new StreamReader(response .GetResponseStream()))
{
JavaScriptSerializer js = new JavaScriptSerializer();
var objText = reader.ReadToEnd();
myojb = (CategoryDataViewModel )js.Deserialize(objText, typeof(CategoryDataViewModel ));
}
}
return myojb;
But then I get Type 'Test.CategoryDataViewModel' is not supported for deserialization of an array.
Change:
myojb = (CategoryDataViewModel )js.Deserialize(objText, typeof(CategoryDataViewModel ));
to:
myojb = (List<CategoryDataViewModel> )js.Deserialize(objText, typeof(List<CategoryDataViewModel>));
and you should be fine. The array will de-serialize to a list no problem.
