Cannot deserialize the current JSON array (e.g. [1,2,3]) into type
提问by sakir
I have a class like this;
我有一堂这样的课；
public class MyStok
{
public int STId { get; set; }
public int SM { get; set; }
public string CA { get; set; }
public string Br { get; set; }
public string BNo { get; set; }
public decimal Vat { get; set; }
public decimal Price { get; set; }
}
I deserilaze like this;
我像这样反序列化；
string sc= e.ExtraParams["sc"].ToString();
MyStok myobj = JSON.Deserialize<MyStok>(sc);
my output seems to like this ( string sc) on fiddler
我的输出似乎像 fiddler 上的这个（字符串 sc）
[
{
"STId": 2,
"CA": "hbh",
"Br": "jhnj",
"SM": 20,
"Vat": 10,
"Price": 566,
"BNo": "1545545"
}
]
but I get the error Cannot deserialize the current JSON array (e.g. [1,2,3]) into type whats wrong in those codes.
但我收到错误无法将当前 JSON 数组（例如 [1,2,3]）反序列化为这些代码中的错误类型。
thank you .
谢谢你 。

It looks like the string contains an array with a single MyStokobject in it. If you remove square brackets from both ends of the input, you should be able to deserialize the data as a single object:
看起来该字符串包含一个数组，其中包含一个MyStok对象。如果从输入的两端删除方括号，您应该能够将数据反序列化为单个对象：
MyStok myobj = JSON.Deserialize<MyStok>(sc.Substring(1, sc.Length-2));
You could also deserialize the array into a list of MyStokobjects, and take the object at index zero.
您还可以将数组反序列化为MyStok对象列表，并在索引为零处获取对象。
var myobjList = JSON.Deserialize<List<MyStok>>(sc);
var myObj = myobjList[0];
回答by Janty
For array type Please try this one.
对于数组类型请尝试这个。
List<MyStok> myDeserializedObjList = (List<MyStok>)Newtonsoft.Json.JsonConvert.DeserializeObject(sc), typeof(List<MyStok>));

HttpClient webClient = new HttpClient();
Uri uri = new Uri("your url");
HttpResponseMessage response = await webClient.GetAsync(uri)
var jsonString = await response.Content.ReadAsStringAsync();
var objData = JsonConvert.DeserializeObject<List<CategoryModel>>(jsonString);
