Question

我正在进行一个API调用，该调用返回JSON（到名为jsonString的变量中）。在JSON数据上进行Console.WriteLine(jsonString)可以显示以下内容：

{“ contentType”：null，“ serializerSettings”：null，“ statusCode”：null，“ value”：“ {\” contentType \“：null，\” serializerSettings \“：null，\” statusCode \“： null，\“ value \”：{\“ 10 \”：\“ ALABAMA \”，\“ 11 \”：\“ ALASKA \”，\“ 12 \”：\“ ARIZONA \”，\“ 13 \” ：\“ ARKANSAS \”，\“ 14 \”：\“ CALIFORNIA \”，\“ 15 \”：\“ COLORADO \”，\“ 16 \”：\“ CONNECTICUT \”，\“ 17 \”：\ “ DELAWARE \”，\“ 18 \”：\“ FLORIDA \”，\“ 19 \”：\“ GEORGIA \”，\“ 20 \”：\“ HAWAII \”，\“ 21 \”：\“ IDAHO \“，\” 22 \“：\” ILLINOIS \“，\” 23 \“：\” INDIANA \“，\” 24 \“：\” IOWA \“，\” 25 \“：\” KANSAS \“ ，\“ 26 \”：\“肯塔基州”，\“ 27 \”：\“ LOUISIANA \”，\“ 28 \”：\“ MAINE \”，\“ 29 \”：\“马里兰州”，\ “ 30 \”：\“ MASSACHUSETTS \”，\“ 31 \”：\“ MICHIGAN \”，\“ 32 \”：\“ MINNESOTA \”，\“ 33 \”：\“ MISSISSIPPI \”，\“ 34 \“：\” MISSOURI \“，\” 35 \“：\” MONTANA \“，\” 36 \“：\” NEBRASKA \“，\” 37 \“：\” NEVADA \“，\” 38 \“ ：\“ NEW HAMPSHIRE \”，\“ 39 \”：\“ NEW JERSEY \”，\“ 40 \”：\“ NEW MEXICO \”，\“ 41 \”：\“ NEW YORK \”，\“ 42 \“：\” NORTH CAROLINA \“，\” 43 \“：\” NORTH DAKOTA \“，\” 44 \“：\” OHIO \“，\” 45 \“：\” OKLAHOMA \“，\” 46 \“：\” OREGON \“，\” 47 \“：\” PENNSYLVANIA \“，\” 48 \“：\” RHODE ISLAND \“，\” 49 \“：\” SOUTH CAROLINA \“，\” 50 \“：\” SOUTH DAKOTA \“，\ “ 51 \”：\“ TENNESSEE \”，\“ 52 \”：\“ TEXAS \”，\“ 53 \”：\“ UTAH \”，\“ 54 \”：\“ VERMONT \”，\“ 55 \“：\” VIRGINIA \“，\” 56 \“：\”华盛顿\“，\” 57 \“：\” WEST VIRGINIA \“，\” 58 \“：\” WISCONSIN \“，\” 59 \ “：\” WYOMING \“}}”}

我正尝试将其反序列化为如下所示的类：

public class LookupValuesResponse
{
    [JsonProperty("value")]
    public Dictionary<int, string> LookupValues;

    [JsonProperty("statusCode")]
    public string Status;

}

我已经尝试过了：

LookupValuesResponse lookupresponse = JsonConvert.DeserializeObject<LookupValuesResponse>(jsonString);

但是，我收到一个无法反序列化JSON的错误：

System.ArgumentException：无法将System.String强制转换或转换为System.Collections.Generic.Dictionary`2 [System.Int32，System.String]。

Answer 1

我需要更改被调用的API返回其结果的方式。以前我有：

return Ok(Json(response.Content.ReadAsStringAsync().Result));

相反，我需要：

return Ok(JsonConvert.DeserializeObject(response.Content.ReadAsStringAsync().Result));

无法将JSON反序列化为字典
