Question

我正在开展项目，其中我将数据从asp.net webform发布到WCF服务。我通过params发布数据，服务回复JSON string。现在我在反序列化方面遇到了问题。我读了很多线程，但没有找到任何解决方案。希望有人能解决我的问题。在此先感谢

来自WCF的回复

{ “LoginResult”：假}

我只想要"false"值。

我是怎么做的：

    string URL = "http://localhost:32319/ServiceEmployeeLogin.svc"; 
    WebRequest wrGETURL;
    wrGETURL = WebRequest.Create(URL+"/"+emp_username+"/"+emp_password+"/"+emp_type);
    wrGETURL.Method = "POST";
    wrGETURL.ContentType = @"application/json; charset=utf-8";
    HttpWebResponse webresponse = wrGETURL.GetResponse() as HttpWebResponse;

    Encoding enc = System.Text.Encoding.GetEncoding("utf-8");
    // read response stream from response object
    StreamReader loResponseStream = new StreamReader(webresponse.GetResponseStream(), enc);

    // read string from stream data
    strResult = loResponseStream.ReadToEnd();

    var jObj = JObject.Parse(strResult);
    var dict = jObj["LoginResult"].Children().Cast<JProperty>();

Answer 1

您可以使用json.net这样做：

public class AuthResponse {
    public bool LoginResult { get; set; }
}

var deserializedResponse = JsonConvert.DeserializeObject<AuthResponse>(strResult);

.Net 4.5有一个JavaScriptSerializer，它也可以运行：

public class AuthResponse {
    public bool LoginResult { get; set; }
}

System.Web.Script.Serialization.JavaScriptSerializer sr = new System.Web.Script.Serialization.JavaScriptSerializer();

AuthResponse response = sr.Deserialize<AuthResponse>(responseText);
