对c#对象发出解析JSON对象响应

本文关键字：对象 JSON 响应 | 更新日期: 2023-09-27 18:01:59

我有以下代码:

[WebMethod]
public bool AddUser(long warnId, double longitude, double latitude)
{
    try
    {
        string jsonFeature = string.Empty;
        jsonFeature += "[{'geometry': {'x': " + longitude + ",'y': " + latitude +
                       ",'spatialReference': {'wkid': 4326}},'attributes': {'UID': '";
        jsonFeature += warnId + "','Latitude': '" + latitude + "','Longitude': '" + longitude + "'}}]";
        string reqURL = System.Configuration.ConfigurationManager.AppSettings["WARNURL"] + "addFeatures";
        using (System.Net.WebClient client = new System.Net.WebClient())
        {
            client.Headers["Content-type"] = "application/x-www-form-urlencoded";
            client.Encoding = System.Text.Encoding.UTF8;
            var collection = new System.Collections.Specialized.NameValueCollection();
            collection.Add("f", "json");
            collection.Add("features", jsonFeature);
            byte[] response = client.UploadValues(reqURL, "POST", collection);
            MemoryStream stream = new MemoryStream(response);
            StreamReader reader = new StreamReader(stream);
            string aRespStr = reader.ReadToEnd();
            JavaScriptSerializer jss = new JavaScriptSerializer();
            AddResult addResult = jss.Deserialize<AddResult>(aRespStr);

            return aRespStr.Contains("true") && aRespStr.Contains("success");
        }
    }
    catch(Exception e)
    {
        string message = e.Message;
        return false;
    }
}

当我运行它时，字符串aRespStr是:

"{'"addResults '":[{' '"objectId '":28日"globalId '",'"{740490 c6 - 77 - ee - 4 - ac0 - 9561 - 5 - ebaace3a0a7}成功'",'"'":真}}"

我创建了以下类来保存对象，一旦我反序列化它:

    public class Error
{
    public int code { get; set; }
    public string description { get; set; }
}
public class AddResult
{
    public int objectId { get; set; }
    public object globalId { get; set; }
    public bool success { get; set; }
    public Error error { get; set; }
}
public class RootObject
{
    public List<AddResult> addResults { get; set; }
}

但是当我运行代码时，addressult对象包含默认对象值而不是json对象值。

任何帮助让这个工作是非常感谢

对c#对象发出解析JSON对象响应

试试这个

RootObject addResults=jss.Deserialize<RootObject>(aRespStr);

或者类似的

List<AddResult> addResults = jss.Deserialize<List<AddResult>>(aRespStr);

，因为你正在返回json响应中的地址结果列表。

并更改内容类型为application/json

change 

client.Headers["Content-type"] = "application/x-www-form-urlencoded";


client.Headers["Content-type"] = "Application/json";
