Web 服务函数调用中的 out 参数出现问题

本文关键字：参数问题 out 服务函数调用 Web | 更新日期: 2023-09-27 17:57:11

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，就像我在服务器端看到的那样。我应该在服务器中做哪些更改，我将在不进行更改的情况下对其进行更改。

知道为什么我在那里看不到 out 参数，为什么我不能使用它吗？

Web 服务函数调用中的 out 参数出现问题

在约翰·桑德斯的帮助下，再次感谢，我知道要搜索什么。

我找到了这个答案如何从 wsdl 生成 Web 服务

这正是我所需要的.

我认为

这个类似的问题可能会对您有所帮助。

Web 服务调用具有"out"参数是否不寻常？

此外，您可以创建一个结构或类，将两个 out 参数捆绑在一起并返回如下内容。

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 );      
}

它将

在LoginResponseBody中。IIRC 将在客户端修改该方法，以便返回一个值。或者也许在LoginRequest里面.
