解析從控制器返回的json。出於某種原因，在返回字典時，我需要對關鍵元素執行「ToString（）」操作，否則會出現錯誤。爲什麼？。樣本是否是正確的方式/序列化JSON的最佳方式？感謝MVC在Json中序列化對象，對象列表，集合
控制器：
// JSON
public ActionResult GizmosJsonObject()
{
var gizmo = new Gizmo
{
Id = 2343,
Name = "Some awesome name",
Quantity = 32,
IntroducedDate = DateTime.Now
};
return this.Json(gizmo);
}
public ActionResult GizmosJsonObjectCollection()
{
var gizmos = new List<Gizmo>();
gizmos.Add(new Gizmo
{
Id = 102,
Name = "some name1",
Quantity = 535,
IntroducedDate = DateTime.Now
});
gizmos.Add(new Gizmo
{
Id = 122,
Name = "some name1",
Quantity = 135,
IntroducedDate = DateTime.Now
});
gizmos.Add(new Gizmo
{
Id = 562,
Name = "some name1",
Quantity = 2,
IntroducedDate = DateTime.Now
});
return this.Json(gizmos);
}
public ActionResult GizmosJsonListInts()
{
var gizmos = new List<int>();
gizmos.Add(2);
gizmos.Add(56);
gizmos.Add(32);
return this.Json(gizmos);
}
public ActionResult GizmosJsonDictionaryInts()
{
var gizmos = new Dictionary<int, int>();
gizmos.Add(23, 123);
gizmos.Add(26, 227);
gizmos.Add(54, 94323);
return this.Json(gizmos.ToDictionary(x => x.Key.ToString(), y => y.Value));
}
public ActionResult GizmosJsonDictionaryStrings()
{
var gizmos = new Dictionary<string, string>();
gizmos.Add("key1", "value1");
gizmos.Add("Key2", "value2");
gizmos.Add("key3", "value3");
return this.Json(gizmos);
}
