Example of WebService with soapheader Verification

The company asked me to write a user interface with another website, as shown below: Code

Using System;
Using System. collections;
Using System. componentmodel;
Using System. Data;
Using System. LINQ;
Using System. Web;
Using System. Web. Services;
Using System. Web. Services. Protocols;
Using System. xml. LINQ;

Namespace Userlogintest
{
///   <Summary>
/// Summary of checkuser
///   </Summary>
[WebService (namespace =   " Http://tempuri.org/ " )]
[Webservicebinding (conformsto = Wsiprofiles. basicprofile1_1)]
[Toolboxitem ( False )]
// To allow ASP. Net ajax to call this web service from a script, uncomment the downstream service.
// [System. Web. Script. Services. scriptservice]
Public   Class Checkuser: system. Web. Services. WebService
{

///   <Summary>
/// Do not verify the Method
///   </Summary>
///   <Returns> </returns>
[Webmethod]
Public   String Helloworld ()
{
Return   " Hello World " ;
}

PublicMysoapheader soaphead= NewMysoapheader ();

///   <Summary>
/// Verification Method
///   </Summary>
///   <Param name = "userid"> </param>
///   <Param name = "username"> </param>
///   <Param name = "MSG"> </param>

[Soapheader ( " Soaphead " )]
[Webmethod]
Public   Bool Getuserinfo ( Int Userid, String Username, Out   String MSG)
{

String Deusername = Encrypthelper. decrypt (username, " Jjjyzy " );
MSG =   String . Empty;
If ( ! Soaphead. isvalid ( Out MSG ))
{ Return   False ;}

Else
{
ReturnCheckcount (userid, deusername );

}

}

///   <Summary>
/// Query ID and account
///   </Summary>
Private   Bool Checkcount ( Int Userid, String Username)
{
String Sqlstr =   " Select Table where id = userid and username = Username " ;

Return True;
}

}

///   <Summary>
/// Soaphead verification method account password LY (override a class)
///   </Summary>
Public   Class Mysoapheader: system. Web. Services. Protocols. soapheader
{
Public   String Wsusername
{ Get ; Set ;}
Public   String Wspwd
{ Get ; Set ;}

PublicMysoapheader ()
{

}

Public   Bool Isvalid ( Out   String MSG)
{
Return Isvalid (wsusername, wspwd, Out MSG );
}
Private   Bool Isvalid ( String Wsusername, String Wspwd, Out   String MSG)

}

}
