Second, code implementation

First, we implement a class for authentication, the filename Authentication.cs to the following code:

Using System;

Namespace Useresdata

{

///

Implementing a File Transfer Web Service with user authentication

///

public class Authentication:System.Web.Services.Protocols.SoapHeader

{

public string Username;

public string Password;

Public Boolean ValidUser (String in_username,

String In_password)

{

if ((In_username = = "Caomo") && (In_password = = "Password"))

{

return true;

}

Else

{

return false;

}

}

Public authentication ()

{

//

Todo:add constructor Logic here

//

}

}

}

The authentication class inherits from System.Web.Services.Protocols.SoapHeader. and defines two member variables, username and password, and defines a user-authenticated function ValidUser. It provides functionality for username and password checks, and you can write it very complex, such as checking the user's effectiveness by accessing the database. I'm here to simply check the equality of fixed values.
