私はオンラインモードでアプリケーションを動作させる/切断し、ASPNET開発者のための書籍HTML5プログラミングの例で動作します。ASPNET LocalStorage Json逆シリアル化
私はASPNETテクノロジMVC5を使用します。
私は私のコントローラ内のデータをデシリアライズするとき、私はエラーを持っている：
public JsonResult SaveResults()
{
string jsonData = string.Empty;
using (StreamReader sr = new StreamReader(Request.InputStream))
{
jsonData = sr.ReadToEnd();
}
Dictionary<string, string> data = JsonConvert.DeserializeObject<Dictionary<string, string>>(jsonData);
SurveyDbEntities db = new SurveyDbEntities();
User usr = new User();
usr.FirstName = data["FirstName"];
usr.LastName = data["LastName"];
usr.Email = data["Email"];
db.Users.AddObject(usr);
db.SaveChanges();
string userEmail = data["Email"];
int usrId = (from item in db.Users
where item.Email == userEmail
select item.UserID).SingleOrDefault();
data.Remove("FirstName");
data.Remove("LastName");
data.Remove("Email");
foreach (string str in data.Keys)
{
int choiceId = int.Parse(str);
int questionId = int.Parse(data[str]);
Result result = new Result();
result.QuestionID = questionId;
result.ChoiceID = choiceId;
result.UserID = usrId;
db.Results.AddObject(result);
}
db.SaveChanges();
return Json("success");
}
この行はエラー
Dictionary<string, string> data = JsonConvert.DeserializeObject<Dictionary<string, string>>(jsonData);
マイjsonData（引用問題？）を示しています。
{"Email":"[email protected]","FirstName":"test","LastName":"test","container":"<div data-questions-questionid="1" class="paddedDiv">Which programming language do you use?<br><input type="checkbox" data-choices-questionid="1" data-choices-choiceid="1"><span>C#</span><br><input type="checkbox" data-choices-questionid="1" data-choices-choiceid="2"><span>VB.NET</span><br><input type="checkbox" data-choices-questionid="1" data-choices-choiceid="3"><span>PHP</span></div><div data-questions-questionid="2" class="paddedDiv">Which of the following browsers do you use while developing websites?<br><input type="checkbox" data-choices-questionid="2" data-choices-choiceid="4"><span>IE9</span><br><input type="checkbox" data-choices-questionid="2" data-choices-choiceid="5"><span>Firefox</span><br><input type="checkbox" data-choices-questionid="2" data-choices-choiceid="6"><span>Chrome</span></div><div data-questions-questionid="3" class="paddedDiv">Which of the following tools do you use?<br><input type="checkbox" data-choices-questionid="3" data-choices-choiceid="7"><span>Visual Studio</span><br><input type="checkbox" data-choices-questionid="3" data-choices-choiceid="8"><span>Web Matrix</span><br><input type="checkbox" data-choices-questionid="3" data-choices-choiceid="9"><span>Expression Web</span></div>"}
をエラー：
{"After parsing a value an unexpected character was encountered: 1. Path 'container', line 1, position 105."}
問題はどこですか？
JavascriptをSubmitData
function SubmitData(event) {
var data = '';
for (var i = 0; i < storage.length; i++) {
var key = storage.key(i);
var value = storage[key];
var pair = '"' + key + '":"' + value + '"';
data = data + pair + ",";
}
if (data.charAt(data.length - 1) == ',') {
data = data.substring(0, data.length - 1)
}
data = '{' + data + '}';
