Question

我创建了android程序，它以JSON格式发送数据，如下所示：

public static String POST(String url, ArrayList<Pers_Ordre>  ListOrdres){
    InputStream inputStream = null;
    String result = "";
    try {

        // 1. create HttpClient
        HttpClient httpclient = new DefaultHttpClient();

        // 2. make POST request to the given URL
        HttpPost httpPost = new HttpPost(url);

        String json = "";

        // 3. build jsonObject
        JSONObject jsonObject = new JSONObject();

        for(Pers_Ordre TheOrdre : ListOrdres){
             jsonObject.accumulate("CodeClient", TheOrdre.getLe_CodeClient());
             jsonObject.accumulate("CodeDest", TheOrdre.getLe_CodeDest());
             jsonObject.accumulate("NoOrdre", TheOrdre.getLe_NoOrdre());
             jsonObject.accumulate("LeDate", "qsdf");
             jsonObject.accumulate("LeGPS", "qsdfqsdf");            
             jsonObject.accumulate("LeStatut", TheOrdre.getLe_Statut());
             jsonObject.accumulate("LeCamion", TheOrdre.getLe_Camion());
            }

        // 4. convert JSONObject to JSON to String
        json = jsonObject.toString();  

        // ** Alternative way to convert Person object to JSON string usin Jackson Lib 
        // ObjectMapper mapper = new ObjectMapper();
        // json = mapper.writeValueAsString(person); 

        // 5. set json to StringEntity
        StringEntity se = new StringEntity(json);

        // 6. set httpPost Entity
        httpPost.setEntity(se);

        // 7. Set some headers to inform server about the type of the content   
        httpPost.setHeader("Accept", "application/json");
        httpPost.setHeader("Content-type", "application/json");

        // 8. Execute POST request to the given URL
        HttpResponse httpResponse = httpclient.execute(httpPost);

        // 9. receive response as inputStream
        inputStream = httpResponse.getEntity().getContent();  


        // 10. convert inputstream to string 
        if(inputStream != null)
            result = convertInputStreamToString(inputStream);
        else 
            result = "Did not work!"; 

    } catch (Exception e) {
        Log.d("InputStream", e.getLocalizedMessage());
    } 

    // 11. return result
    return result; 
}

当我调试它时，我的json数据是：

{"LeDate":"20\/08\/2014 09:15","LeStatut":"1","CodeClient":"140056","NoOrdre":"26754","CodeDest":"1026","LeCamion":"Camion A"}

我不知道我是如何在我的WCF程序中使用这个JSON的。我知道它称之为连接并调用我的服务，因为当我用这样的非感知数据进行测试时：

  comm_Insrt.Parameters.AddWithValue("@CODE_CLIENT", "454548");
                    comm_Insrt.Parameters.AddWithValue("@CODE_DEST", "44444");
                    comm_Insrt.Parameters.AddWithValue("@NO_ORDRE", "545454545");
                    comm_Insrt.Parameters.AddWithValue("@DATE_TAMPON", "2013-05-03 15:01:16.920");
                    comm_Insrt.Parameters.AddWithValue("@GPS_POS", "fsdgsgsg");
                    comm_Insrt.Parameters.AddWithValue("@STATUS_ORDRE", "65");
                    comm_Insrt.Parameters.AddWithValue("@CAMION", "fgfgf");
                    comm_Insrt.ExecuteNonQuery();

它插入我的SQL sever 2008 R2。

这是我的服务：

namespace WcfService_SuiviColis

        public void SaveData(Pers_Ordre_NET Oodre)
        { 
            try
            {
                //var data = Oodre.Split('|');
                //var response = new Pers_Ordre_NET

            }
            catch (Exception excThrown)
            {

            }
        }    
    }   
}

EDITED

我也尝试以字符串格式获取数据，然后我会像这样使用它：

   public void SaveData(String Oodre)
            { 
                try
                {
                    var data = Oodre.Split(',');
                    var response = new Pers_Ordre_NET
                    {
                        CodeClient = data[0],
                       CodeDest = data[1],
                        NoOrdre = data[2],
                       LeDate = data[3]
                   };

但是我遇到了错误问题，对象类型为String的deserialiosation，找到了元素LeDate ....

我也试过这样：

  public void SaveData(byte[] abc)
        { 
            try
            {  

                Stream strm = new MemoryStream(abc);
                DataContractSerializer obj = new DataContractSerializer(typeof(string));
                string result = obj.ReadObject(strm).ToString();

仍然是同样的错误....我如何在WCF中使用JSON数据？

我解决了。只需将名称放在数据成员

上

 [DataContract]
    public class Pers_Ordre_NET
    {
        [DataMember(Name = "CodeClient")]
        string _CodeClient;
        public string CodeClient
        {
            get { return _CodeClient; }
            set { _CodeClient = value; }
        }

       [DataMember(Name = "CodeDest")]
        string _CodeDest;
        public string CodeDest
        {
            get { return _CodeDest; }
            set { _CodeDest = value; }
        }

        [DataMember(Name = "NoOrdre")]
        string _NoOrdre;

            set { _NoOrdre = value; }
        }

            set { _LeDate = value; }
        }

        }
