将数据从ios应用程序传递到C＃web服务

我正在尝试开发此iOS应用程序，该应用程序可以与本地网络下的C＃Web服务进行通信。我正在使用AFNetworking来实现通信。现在我已经在this tutorial的帮助下完成了从Web服务中读取XML数据，这意味着我的应用可以连接到Web服务。但我真正想做的是将数据从应用程序传递到Web服务。我有写一些示例代码：将数据从ios应用程序传递到C＃web服务

AFmyAPIClient *myClient = [AFmyAPIClient sharedClient]; 
NSMutableDictionary *requestArray = [NSMutableDictionary new]; 
NSString *details = [_listOfItems description]; 
float tempF= [_listOfItems totalPrice]; 
NSString *price = [NSString stringWithFormat:@"%f",tempF]; 
int tempI = 1; 
NSString *table = [NSString stringWithFormat:@"%u",tempI]; 

[requestArray setObject:details forKey:@"details"]; 
[requestArray setObject:price forKey:@"price"]; 
[requestArray setObject:table forKey:@"table"]; 

[myClient postPath:@"setOrderDetails" parameters:requestArray success:^(AFHTTPRequestOperation *operation, id responseObject) { 
     NSLog(@"success!"); 
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
     NSLog(@"%@",error); 
    }];

我建立并运行这个程序之后，它生成此错误消息：

2013-11-03 16:25:48.654 HLR[16149:70b] <?xml version="1.0" encoding="utf-8"?>

    "Cache-Control" = private; 
    "Content-Length" = 34; 
    "Content-Type" = "text/plain; charset=utf-8"; 
    Date = "Sun, 03 Nov 2013 05:25:34 GMT"; 
    Server = "Microsoft-IIS/7.5"; 
    "X-AspNet-Version" = "2.0.50727"; 
    "X-Powered-By" = "ASP.NET"; 
} }}

在我的C＃的Web服务方面，我有这样的Web方法：

[Web Method] 
public void setOrderDetails(String orderDetails) 
{ 
     //store orderDetails into a text file. 

}

我是新来的iOS开发，我不明白为什么我真的传递到Web服务时，我调用此方法：

[myClient postPath:@"setOrderDetails" parameters:requestArray success:^(AFHTTPRequestOperation *operation, id responseObject) { 
      NSLog(@"success!"); 
     } failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
      NSLog(@"%@",error); 
     }];

我只是将一个NSDictionary作为参数传递给C＃web服务？如果是这样的话，我可以在Web服务端使用这个NSDictionary做什么？

我不知道这是否是实现将数据传递到Web服务的正确方法。我真正想在这里做的是将一些字符串传递给Web服务，我该如何实现？

任何建议将不胜感激！
