通过SoapHeader对用户口令进行验证，只有授权的用户才可以使用接口。确保了访问接口用户的安全性。

public MySoapHeader myHeader = new MySoapHeader();

    public SoapHeaderService()

    {

        //Uncomment the following line if using designed components

        //InitializeComponent();

    }

    //普通方法，不需要SoapHeader验证

    [WebMethod(Description = "普通方法不需要验证")]

    public string HelloWorld(string msg) {

        if (msg == "")

            msg = "default message:" + "Hello World";

        else

            msg = "The message you have input is " + msg;

        return msg;

    }

    //需要SoapHeader验证

    [SoapHeader("myHeader")]

    [WebMethod(Description="需要SoapHeader验证  ", EnableSession = true)]

    public string GetSecurityService(string inmsg)

    {

        string msg = "";

        //验证是否有权访问

        if (!myHeader.IsValid(out  msg))

        {

            return msg;//返回错误信息

        }

        inmsg = "Security Message: " + inmsg;

        return inmsg;

    } 

SoapHeader验证，本文未连接数据库，仅仅将验证写死了，需要的可以自己改。
