REST WCF 使得我们调用Web服务时，可以通过HttpRequest的交互简单完成。那么老版的WebService能否做到呢？WebService中通过HttpContext.Current.Rquest/Response，我们一样也可以改造WebMethod。

客户端：


// 创建一个DataTable 
DataTable data = new DataTable("Project"); 
data.Columns.Add("Name"); 
data.Columns.Add("Birthday"); 
data.Rows.Add(new object[] { "Wendy", "1978/03/11" }); 
data.Rows.Add(new object[] { "Philip", "2000/11/05" }); 
data.Rows.Add(new object[] { "Felix", "1999/08/04" }); 
using (var ms = new MemoryStream()) 
{ 
 // 将DataTable用Xml格式写入流 
 data.WriteXml(ms, XmlWriteMode.WriteSchema); 
 var client = new WebClient(); 
 // 定义HttpRequest的Content-Type(xml,json等) 
 client.Headers.Add("Content-Type", "text/xml"); 
 var url = "http://localhost:2609/Service1.asmx/SendXml"; 
 // Send HttpRequest 
 var resp = client.UploadData(url, "POST", ms.ToArray()); 
 var strResp = System.Text.Encoding.UTF8.GetString(resp); 
 MessageBox.Show(strResp); 
}

服务端：


[WebMethod] 
public void SendXml() 
{ 
 // 获得客户端RAW HttpRequest 
 var inputStream = HttpContext.Current.Request.InputStream; 
 // 定义Response返回的格式是:Json 
 var response = HttpContext.Current.Response; 
 response.ContentType = "text/json"; 
 //var strXml = ""; 
 //using (var sr = new StreamReader(inputStream)) 
 // strXml = sr.ReadToEnd(); 
 try 
 { 
 DataTable data = new DataTable(); 
 using (var xr = XmlReader.Create(inputStream)) 
 data.ReadXml(xr); 
 // 将读入Xml的DataTable的行数返回客户端 
 string count = "/"" + data.Rows.Count + "/""; 
 response.BinaryWrite(System.Text.Encoding.UTF8.GetBytes(count)); 
 } 
 catch (Exception ex) 
 { 
 response.BinaryWrite(System.Text.Encoding.UTF8.GetBytes(ex.Message)); 
 } 
}
