實現原理，通過POST SOAP 1.2協議內容，實現復雜對象的傳入
POST /Main.asmx HTTP/1.1
Host: localhost
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length
<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
? <soap12:Body>
??? <HelloWorld xmlns="http://tempuri.org/">
????? <user>
??????? <UserID>int</UserID>
??????? <UserName>string</UserName>
????? </user>
??? </HelloWorld>
? </soap12:Body>
</soap12:Envelope>
WebService User.cs 傳入對象
??? public class User
??? {
??????? public int UserID { get; set; }
??????? public string UserName { get; set; }
??? }
WebService Main.asmx.cs 服務
??? [WebService(Namespace = "http://tempuri.org/")]
??? [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
??? [System.ComponentModel.ToolboxItem(false)]
??? // 若要允許使用 ASP.NET AJAX 從腳本中調用此 Web 服務，請取消對下行的注釋。
??? [System.Web.Script.Services.ScriptService]
??? public class Main : System.Web.Services.WebService
??? {
??????? [WebMethod]
??????? public string HelloWorld(User user)
??????? {
??????????? return "Hello World" + user.UserName;
??????? }
??? }
