enter code here我一直使用ASP.NET MVC 3應用程序運行此異常。字典插入導致錯誤'具有相同密鑰的項目已被添加'
該項目有兩個簡單的分類。項目和訂單。項目的創建工作正常，但是當我嘗試創建一個訂單時，它仍然與下面的說明一起失敗。
{ 「requestigAppLead」： 「DDD」， 「requestingApplication」： 「悲」， 「responsibleApp」： 「FFF」， 「responsibleAppLead」： 「DDD」} [ArgumentException的：具有相同鍵的項已被添加。] System.ThrowHelper.ThrowArgumentException（ExceptionResource資源）52 System.Collections.Generic.Dictionary
2.Insert(TKey key, TValue value, Boolean add) +9374523 System.Linq.Enumerable.ToDictionary(IEnumerable1種源，函數功能2 keySelector, Func2 elementSelector，IEqualityComparer`1比較器）252
我仍然看到同樣的問題。以下是完整的細節。

Control Code:

public ActionResult Create()
{
ViewBag.projectID = new SelectList(db.Projects.ToList(), "projectID", "projectName");
ViewBag.orderStatusID = new SelectList(db.OrderStatuses.ToList(), "orderStatusID", "description");
return View();
}
按照下面的要求添加更多細節。
//
// Populate project details
//
[HttpGet]
public virtual JsonResult SelectProject(long? id)
{
Project project = this.db.Projects.Find(1);
var result = new { project.requestigAppLead,
project.requestingApplication,
project.responsibleApp,
project.responsibleAppLead
};
//ViewBag.projectID = new SelectList(db.Projects, "projectID", "projectName",id.ToString());
//return View(order);
return Json(result, JsonRequestBehavior.AllowGet);
}
//
// POST: /Order/Create
[HttpPost, ActionName("Create")]
public ActionResult Create(Order order)
{
if (ModelState.IsValid)
{
//
// TO DO: if the order count is more than threshold raise an alert to the user and send an email to
// leads
//
order.createDateTime = DateTime.Now;
order.updateDateTime = DateTime.Now;
db.Orders.Add(order);
db.SaveChanges();
// send email
util.EmailUtil.SendEmail(order);
return RedirectToAction("Index");
}
ViewBag.projectID = new SelectList(db.Projects, "projectID", "projectName", order.projectProjectID);
return View(order);
}
這個異常不像實際導致異常**的**代碼那麼重要。編輯您的問題以將代碼添加到字典中。 –
JSON是否顯示請求失敗的整個機構？如果沒有，請顯示所有正在提交的JSON。 – counsellorben
我已經添加了上面的代碼來顯示HttpGet和HttpPost方法。當用戶選擇項目下拉菜單時，也包括一種用於獲取Jason數據的方法。 – user959671
