Question

我正在尝试将自定义对象和2个字符串值传递给启用了REST和SOAP的WCF服务

以下是服务合同

[OperationContract]
     [WebInvoke(UriTemplate = "/AddData/{Name}/{Id}", RequestFormat = WebMessageFormat.Json,
            ResponseFormat = WebMessageFormat.Json, Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped )]
           bool AddData(CustomData itm,string Name, string Id);

然后我有示例代码尝试使用HTTP Client调用服务，我遇到的问题是字符串值传入但对象值为null

我不确定我是否定义了错误的服务或错误地调用了服务？

private async void button1_Click(object sender, EventArgs e)
    {
        try
        {
 var client = new HttpClient();
            var uri = new Uri("http://localhost:52309/Service1.svc/rest/AddData/test/1");

            CustomData data = new  CustomData ();
            data.description = "TEST";
            data.fieldid = "test1";
            data.fieldvalue = "BLA";

            string postBody = JsonSerializer(data);

            HttpContent contentPost = new StringContent(postBody , Encoding.UTF8, "application/json");
            HttpResponseMessage wcfResponse = await client.PostAsync(uri, contentPost).ContinueWith((postTask) => postTask.Result.EnsureSuccessStatusCode());


            client.Dispose();
 string responJsonText = await wcfResponse.Content.ReadAsStringAsync();

 }
        catch (Exception ex)
        {

        }
}

public string JsonSerializer(FormsData  objectToSerialize)
    {
        if (objectToSerialize == null)
        {
            throw new ArgumentException("objectToSerialize must not be null");
        }
        MemoryStream ms = null;

        DataContractJsonSerializer serializer = new DataContractJsonSerializer(objectToSerialize.GetType());
        ms = new MemoryStream();
        serializer.WriteObject(ms, objectToSerialize);
        ms.Seek(0, SeekOrigin.Begin);
        StreamReader sr = new StreamReader(ms);
        return sr.ReadToEnd();
    }

我通过添加解决了这个问题 [DataContract(Namespace = "CustomData")]和[DataMember(Name = "fieldvalue")]到类定义中的每个变量，然后使用PostAsJsonAsync调用它并直接传递对象。感谢@DanielPark和@DavidG指出了正确的方向

c＃将对象传递给启用REST的WCF服务
