C# WCF动态json到字典

我正在使用ASPX4.5
客户端发送一个带有动态字段的JSON对象（每次可以不同）

在服务器端，我试图将JSON转换为字典，但出现错误500

[OperationContract]
    [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]
    public String StoreFormData(dynamic formData) 
    {
        JavaScriptSerializer jss = new JavaScriptSerializer();
        Dictionary<string, string> formValues = jss.Deserialize<Dictionary<string, string>>(formData);


        return "aaaaa";
    }

[运营合同]
[WebInvoke（Method=“POST”，RequestFormat=WebMessageFormat.Json，ResponseFormat=WebMessageFormat.Json，BodyStyle=WebMessageBodyStyle.WrappedRequest）]
公共字符串StoreFormData（动态formData）
{
JavaScriptSerializer jss=新的JavaScriptSerializer（）；
字典formValues=jss.Deserialize（formData）；
返回“AAAA”；
}

我做错了什么？

当您希望将原始数据接收到方法参数中时，您必须以以下方式实现您的方法：

[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "form/data",
    RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]
public String StoreFormData(Stream fileContents)
{
    using (StreamReader reader = new StreamReader(fileContents))
    {
        JavaScriptSerializer jsSerializer = new JavaScriptSerializer();

        //here is your json, received from a client
        string jsonData = reader.ReadToEnd();

        // I think for that you case it's better to use Newtonsoft.Json library. It will allow you to parse more complex data
        //JObject data = JObject.Parse(jsonData); 

        //Dictionary<string, string> formValues = jss.Deserialize<Dictionary<string, string>>(formData);
    }

    return "aaaaa";
}

有两个问题：
1.我使用了@Legart提到的dynamic。
2.该参数是一个json对象。

有一个可行的解决方案：

function storeDataInSession(formData) {
    var data = {};
    data["formData"] = JSON.stringify(formData);

    $.ajax({
        url: "MYURL/StoreFormData",
        type: "post",
        data: JSON.stringify(data),
        contentType: 'application/json',
        dataType: 'json',
        success: function (data, textStatus, xhr) {
            console.log(data);
            console.log("success");
        },
        error: function (xhr, textStatus, errorThrown) {
            console.log("failure");
        }
    });
}

服务器端：

[OperationContract]
    [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]
    public String StoreFormData(string formData) 
    {        
        JavaScriptSerializer jss = new JavaScriptSerializer();
        Dictionary<string, string> formValues = jss.Deserialize<Dictionary<string, string>>(formData);

        string test = "test:  ";
        foreach (KeyValuePair<string, string> item in formValues) 
        {
            test += String.Format(" key: {0}  value: {1} ", item.Key, item.Value);
        }



        return formData;
    }

{

字典formValues=jss.Deserialize（formData）；
string test=“test:”；
foreach（formValues中的KeyValuePair项）
{
test+=String.Format（“key:{0}值：{1}”，item.key，item.value）；
}
返回表单数据；
}

将错误处理添加到您的服务中它将有助于找出错误：错误：错误：无法从MyUrl获取元数据我注意到您使用了动态。WCF是不允许的

function storeDataInSession(formData) {
    var data = {};
    data["formData"] = JSON.stringify(formData);

    $.ajax({
        url: "MYURL/StoreFormData",
        type: "post",
        data: JSON.stringify(data),
        contentType: 'application/json',
        dataType: 'json',
        success: function (data, textStatus, xhr) {
            console.log(data);
            console.log("success");
        },
        error: function (xhr, textStatus, errorThrown) {
            console.log("failure");
        }
    });
}

[OperationContract]
    [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]
    public String StoreFormData(string formData) 
    {        
        JavaScriptSerializer jss = new JavaScriptSerializer();
        Dictionary<string, string> formValues = jss.Deserialize<Dictionary<string, string>>(formData);

        string test = "test:  ";
        foreach (KeyValuePair<string, string> item in formValues) 
        {
            test += String.Format(" key: {0}  value: {1} ", item.Key, item.Value);
        }



        return formData;
    }
