【问题描述】:
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,\"globalId\":\"{740490C6-77EE-4AC0-9561-5EBAACE3A0A7} \",\"成功\":true}]}"
在反序列化对象后,我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。

非常感谢任何有关使其正常工作的帮助
【问题讨论】:
-
字符串与您的 RootObject 类匹配,但您在代码示例中反序列化为 AddResult。
-
感谢 bmavity,当我将其更改为反序列化为 RootObject 时效果很好
