xml菜鸟问题
实现一个功能就是 我这里上传一个xml数据给对方服务器的webservice,但是断点调试发现,执行到 var resp = client.UploadData(url, "POST", ms.ToArray()); 这一步就报错: 远程服务器返回错误: (500) 内部服务器错误。

代码如下:
private void Form1_Load(object sender, EventArgs e)
  {
  DataTable data = new DataTable("Project");
  data.Columns.Add("SIM");
  data.Columns.Add("LPN");
  data.Columns.Add("longitude");
  data.Columns.Add("latitude");
  data.Columns.Add("speed");
  data.Columns.Add("direction");
  data.Columns.Add("operationStatus");
  data.Columns.Add("statusDesc");
  data.Columns.Add("gpstime");
  data.Rows.Add(new object[] { "13216654124","", 121.25089, 30.16242, 50, 102, 0, "", "2012-06-27 15:22:52"});  
  using (var ms = new MemoryStream())  
  {  
  // 将DataTable用Xml格式写入流  
  data.WriteXml(ms, XmlWriteMode.WriteSchema);  
  WebClient client = new WebClient();  
  // 定义HttpRequest的Content-Type(xml,json等)  
  client.Headers.Add("Content-Type", "text/xml");
  string url = "http://61.164.66.141:8082/GPSUploadService.asmx?op=SyncGPS";  
  // Send HttpRequest  
  var resp = client.UploadData(url, "POST", ms.ToArray());  
  var strResp = System.Text.Encoding.UTF8.GetString(resp);  
  MessageBox.Show(strResp);  
  }  
  }

是不是我生成的xml有问题,我看了下不是 soap格式,本人菜鸟,如何写才可以变成soap格式的xml呢?

------解决方案--------------------
1. 直接添加ServiceReference,就可以直接以对象方式调用了。

var client = new GPSService.GPSUploadServiceSoapClient();
client.SyncGPS("13216654124","", 121.25089, 30.16242, 50, 102, 0, "", "2012-06-27 15:22:52");

2. 用post如下:
C# code

var client = new WebClient();
            client.Headers.Add("SOAPAction: \"http://tempuri.org/SyncGPS\"");
            client.Headers.Add("Content-Type: text/xml; charset=utf-8");

            var data = new DataTable("SyncGPS");
            data.Columns.Add("SIM");
            data.Columns.Add("LPN");
            data.Columns.Add("longitude");
            data.Columns.Add("latitude");
            data.Columns.Add("speed");
            data.Columns.Add("direction");
            data.Columns.Add("operationStatus");
            data.Columns.Add("statusDesc");
            data.Columns.Add("gpstime");

            data.Rows.Add(new object[] { "13216654124", "", 121.25089, 30.16242, 50, 102, 0, "", "2012-06-27 15:22:52" });

            using (var sw = new StringWriter())
            {
                data.WriteXml(sw);
                var body = sw.ToString();
                var xdoc = new XmlDocument();
                xdoc.LoadXml(body);
                body = xdoc.FirstChild.InnerXml;
                
                var xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?>";
                xml += "<s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\">";
                xml += "<s:Body>";
                xml += body;
                xml += "</s:Body>";
                xml += "</s:Envelope>";

                var result = client.UploadString("http://61.164.66.141:8082/GPSUploadService.asmx", "POST", xml);
                Console.WriteLine(resu
