Question

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 \ “：[{\” 的ObjectID \ “：28，\” globalId \ “：\”{740490C6-77EE-4AC0-9561-5EBAACE3A0A7} \ “\ ”成功\“：真}]}”

我在反序列化后创建了以下类来保存对象：

    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，addResult对象包含默认对象值而不是json对象值。

非常感谢任何帮助实现这一目标的帮助

Answer 1

试试这个

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

或类似的你可以尝试这个

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

当您在json Response中返回AddResult列表时。

并将内容类型更改为application / json

Answer 2

更改

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

到

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