如何在c#中设置soapHeader进行身份验证？

我想编写一个c#客户端来使用web服务，在添加服务引用并获得代理类后，我编写如下代码：

        private void button1_Click(object sender, EventArgs e)
        {

            servicePortTypeClient sc = new servicePortTypeClient();

            string stID=sc.getTableByTitle("Equipment");
        }

但是当我运行这段代码时，我得到一个例外：错误的授权参数

有一些关于如何使用此web服务的代码，但这些代码是由php编写的，下面是示例：

  $client = new SoapClient(
    'https://rtu2/mvtspro/extensions/service/?wsdl',
    array(
       'timeout' => 1000
     )
   );
   $headers = array();
   $headers[] = new  SoapHeader('http://merasystems.com/auth','Login','admin');
   $headers[] = new  SoapHeader('http://merasystems.com/auth','Password','admin');
   $client->__setSoapHeaders($headers);

我想我可能在如何使用服务器进行身份验证方面有一些错误，但我不知道如何编写代码来实现这一点，有人能理解吗

以下是该服务的wsdl文档：

您可以像这样将凭据发送到WCF服务

servicePortTypeClient sc = new servicePortTypeClient();

sc.ClientCredentials.UserName.UserName = yourUserName;
sc.ClientCredentials.UserName.Password = yourPassword

string stID=sc.getTableByTitle("Equipment");

谢谢，我已经尝试过了，但是仍然得到一个异常“错误的授权参数”，这是否表明我的用户名或pwd不正确？这是第三方web服务，所以我只能获取wsdl文档，在wsdl中，我没有找到任何“soaphead”定义，但是这个服务的api文档确实需要用户名和密码才能进行身份验证，有人能告诉我原因吗？
