C# Json反序列化在C window 2012服务器中不起作用
我正在尝试反序列化C中RESTWebserive中的json字符串。下面是我使用的jsonstring和类。但在反序列化之后，它在服务器上给出了null/empty值。但在本地，它的工作与预期的一样。那我怎么了 Json字符串 RESTWebService调用 我的班级 在my local with local URL中，我能够反序列化json字符串并将其分配给partnerdata。在服务器windows 2012中，在部署到IIS8.5后，参数值为null/空，反序列化时没有错误。Rest WS正在发送预期的响应。和response.error此值已正确反序列化，但参数未反序列化。C# Json反序列化在C window 2012服务器中不起作用,c#,json,rest,serialization,C#,Json,Rest,Serialization,我正在尝试反序列化C中RESTWebserive中的json字符串。下面是我使用的jsonstring和类。但在反序列化之后，它在服务器上给出了null/empty值。但在本地，它的工作与预期的一样。那我怎么了 Json字符串 RESTWebService调用 我的班级 在my local with local URL中，我能够反序列化json字符串并将其分配给partnerdata。在服务器windows 2012中，在部署到IIS8.5后，参数值为null/空，反序列化时没有错误。Rest
那么我怎么了？在您显示的JSON字符串中，参数是一个名称/值对数组： 您的代码试图将参数反序列化为具有多个属性的单个对象，例如： 换句话说，您为ParametersCor接收的JSON响应的是一个列表，而不是一个具有各种属性的POCO 更新 考虑到这是一个使用较旧版本的.Net的遗留应用程序，可能存在一些配置问题，因为var关键字会导致出现编译器错误，我建议切换到内置的.Net组件。按如下方式更改数据模型：
public class PartnerDataDictionary
{
public PartnerDataDictionary()
{
this.ParameterDictionary = new Dictionary<string, string>();
}
string _error;
public string error { get { return _error; } set { _error = value; } }
string _message;
public string message { get { return _message; } set { _message = value; } }
[System.Web.Script.Serialization.ScriptIgnore]
public Dictionary<string, string> ParameterDictionary { get; set; }
public List<Dictionary<string, string>> parameters
{
get
{
List<Dictionary<string, string>> dictList = new List<Dictionary<string, string>>();
foreach (KeyValuePair<string, string> pair in ParameterDictionary)
{
Dictionary<string, string> subDict = new Dictionary<string,string>(1);
subDict[pair.Key] = pair.Value;
dictList.Add(subDict);
}
return dictList;
}
set
{
if (value == null)
{
ParameterDictionary = new Dictionary<string, string>();
return;
}
Dictionary<string, string> dict = new Dictionary<string, string>();
foreach (Dictionary<string, string> entry in value)
foreach (KeyValuePair<string, string> pair in entry)
dict.Add(pair.Key, pair.Value);
ParameterDictionary = dict;
}
}
public string GetParameter(string key)
{
string value;
if (ParameterDictionary.TryGetValue(key, out value))
return value;
return null;
}
public void SetParameter(string key, string value)
{
ParameterDictionary[key] = value;
}
// Add other properties as needed, marking them as `ScriptIgnore`:
[System.Web.Script.Serialization.ScriptIgnore]
public string Programs
{
get { return GetParameter("Programs"); }
set { SetParameter("Programs", value); }
}
}
PartnerDataDictionary data = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<PartnerDataDictionary>(json);
string programs = data.Programs;
Debug.WriteLine(programs);
var settings = new DataContractJsonSerializerSettings
{
UseSimpleDictionaryFormat = true,
DataContractSurrogate = new ObjectToPropertyDictionaryArraySurrogate<Paramter>(),
};
DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof(PartnerData), settings);
您如何连接到DataContractJsonSerializer？愿意改用Json.NET吗？顺便说一句，您应该将所有可处理的内容（如receiveStream）和响应封装在语句中。
