Question

我的网络服务中有以下功能：

[WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
    // [System.Web.Script.Services.ScriptService]
 public class Service1 : System.Web.Services.WebService
    {

        [WebMethod]
        public string HelloWorld()
        {
            return "Hello World";

        }

        [WebMethod]
        public void Login(string url, string id, out int ClientType, out int ClientID)
        {
            ClientID = 11;
            ClientType = 12;
        }
    }
}

在客户端，我在对象引用中看到它没有out参数这是整个代码，我对public void Login(string url, string id, out int ClientType, out int ClientID)感兴趣，我只想在客户端使用，因为我在服务器端。我应该在服务器上做什么改变，我会用它来改变它。

我知道为什么我没有看到out参数，以及为什么我不能使用它？

Answer 1

在John Saunders的帮助下，再次感谢，我知道该搜索什么。

我找到了这个答案how to generate web service out of wsdl

这正是我所需要的。

Answer 2

我认为这个类似的问题可能会帮助你。

Is it unusual for a web service call to have an "out" parameter?

另外，你可以创建一个结构或类来捆绑你的两个输出参数并返回类似这样的东西。

public class LoginResult
{
    public LoginResult(int clientType, int clientId)
    {
         ClientType = clientType;
         ClientID = clientId;
    }

    public int ClientType { get; set; };
    public int ClientID{ get; set; };
}

[WebMethod]        
public LoginResult Login(string url, string id)
{
    return new LoginResult( 11, 12 );      
}

Answer 3

它将在LoginResponseBody中。 IIRC将在客户端修改该方法，以便它返回一个值。或者也许在LoginRequest内。
