Asp.net頁面中調用soapheader進行驗證的操作步驟

<soap:Header>
 <UserSoapHeader xmlns="http://tempuri.org/">
 <UserName>string</UserName>
 <Pwd>string</Pwd>
 </UserSoapHeader>
</soap:Header>

public class UserSoapHeader : SoapHeader
{
 private string _userName;
 private string _pwd;
 
 //public的屬性將自動生成xml結點
 public string UserName
 {
 get { return _userName; }
 set { _userName = value; }
 }
 
 public string Pwd
 {
 get { return _pwd; }
 set { _pwd = value; }
 }
}

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class WebService : System.Web.Services.WebService
{
//此屬性將作為驗證屬性
//方法的SoapHeaderAttribute中的名稱與此變量一致
 public UserSoapHeader userHeader;
 
 public WebService()
 {
 //如果使用設計的組件，請取消注釋以下行
 //InitializeComponent();
 }
 
 [WebMethod]
 [SoapHeader("userHeader")]//這里很重要，名稱要和定義的驗證屬性名稱一致!
 public string HelloWorld()
 {
 //進入此方法后，userHeader將自動有值
 if (userHeader != null)
 {
 return "this is retVal : " + userHeader.UserName;
 }
 return " check not successed ";
 }
}

WebService s = new WebService();
 UserSoapHeader a = new UserSoapHeader();
 a.UserName = "admin";
 a.Pwd = "zz";
 s.UserSoapHeaderValue = a; //此屬性是自動生成的
 Response.Write( s.HelloWorld() ); // this is retVal : admin
