如何从iOS向c#web服务发送数据

我已经开发了一个c#rest web服务来与我的iPad应用程序进行通信，到目前为止，我使用它没有任何问题。这是一件非常简单的事情，到目前为止，有几个查询和GET方法对我来说非常有效。现在的问题是，我正试图将数据从我的应用程序发送到web服务，以插入到我的数据库中

NSString*query=[nsstringwithformat:@“http:mywebsite.com”]；
_URL=[[NSURL alloc]initWithString:query]；
NSMutableURLRequest*request=[[NSMutableURLRequest alloc]initWithURL:[URL缓存策略：NSURLRequestReloadIgnoringCacheData timeoutInterval:15.0]；
[请求设置HttpMethod:@“POST”]；
[请求addValue:@“应用程序/json”用于HttpHeaderField:@“内容类型”]；
[请求addValue:@“应用程序/json”用于HttpHeaderField:@“接受”]；
NSData*requestData=[NSData dataWithBytes:[json UTF8String]长度：[json长度]]；
[请求setHTTPBody:requestData]；
NSURLConnection*connection=[[NSURLConnection alloc]initWithRequest:request委托：自启动中间：YES]；

这基本上是我的objective-C代码，我尝试建立连接，将http方法设置为post并对要发送的NSData进行编码。这个NSData只是一个json字符串，已经可以使用了

现在在我的web服务中，我尝试使用字节[]获取这个NSData，并将其解码为字符串，获取json等等。问题是我做不到。我的web服务方法代码是：

[WebMethod]
[ScriptMethod（ResponseFormat=ResponseFormat.Json，XmlSerializeString=false）]
公共布尔提交结果（字节[]数据）{
String jsonString=System.Text.Encoding.UTF8.GetString（数据）；
试一试{
JavaScriptSerializer json=新的JavaScriptSerializer（）；
var resultado=json.Deserialize（jsonString）；

…然后继续。恢复所有这些：我无法将数据发送到web服务，因此我可以将其插入数据库。任何帮助都将不胜感激

顺便说一句，我得到的错误是这样可怕的事情：

{“Message”：“Type\u0027System.Collections.Generic.IDictionary`2[[System.String，mscorlib，Version=2.0.0.0，Culture=neutral，PublicKeyToken=b77a5c561934e089]，[System.Object，mscorlib，Version=2.0.0.0，Culture=neutral，PublicKeyToken=b77a5c561934e089]。\u0027不支持数组的反序列化。”，“StackTrace”：“位于System.Web.Script.Serialization.ObjectConverter.ConvertListToObject（IList列表，类型类型，JavaScriptSerializer序列化程序，布尔throwOnError，IList&convertedList）\r\n位于System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal”（对象o，类型，JavaScriptSerializer序列化程序，布尔throwOnError，对象和转换对象）\r\n位于System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain（对象o，类型，JavaScriptSerializer序列化程序，布尔throwOnError，对象和转换对象）\r\n位于System.Web.Script.Serialization.JavaScriptSerializer.Deserialize（JavaScriptSerializer serializer，字符串输入，类型，Int32 depthLimit）\r\n位于System.Web.Script.Serialization.JavaScriptSerializer.Deserialize[T]（字符串输入）\r\n位于System.Web.Script.Services.RestHandler.ExecuteWebServiceCall（HttpContext上下文，WebServiceMethodData methodData）”，“异常类型”：“System.InvalidOperationException”}

所以，为了帮助你帮助我，这里是我的json:=）

更新：

经过大量研究，我认为这与我在Xcode中的序列化有关。它是这样的：
