尝试在构造函数中传递接口时，我的泛型类中的错误

Question

在这里，我有 15 种以上调用 SOAP Web 服务的方法中的 2 种

       public async void CallWebServiceA() {
            var client = new WebServiceWRGClient();
            var binding = new BasicHttpBinding(BasicHttpSecurityMode.Transport);
            binding.MaxReceivedMessageSize = Int32.MaxValue;
            binding.MaxBufferSize = Int32.MaxValue;
            var endpoint = new EndpointAddress("https://trustonline.delawarecpf.com/tows/webservicewrg.svc"); 
            var channelFactory = new ChannelFactory<WebServiceWRG>(binding, endpoint);
            var webService = channelFactory.CreateChannel();
            var user = new GRACE_GRACES.User();
            user.UserName = await webService.EncryptValueAsync("username");
            user.Password = await webService.EncryptValueAsync("password12345");
            var response = await client.ClaimSearchAsync(user, "", "", 12345, GRACE_GRACES.statuscode.NotSet, "");
       }

       public async void CallWebServiceB() {
            var client = new WebServiceAWIClient();
            var binding = new BasicHttpBinding(BasicHttpSecurityMode.Transport);
            binding.MaxReceivedMessageSize = Int32.MaxValue;
            binding.MaxBufferSize = Int32.MaxValue;
            var endpoint = new EndpointAddress("https://trustonline.delawarecpf.com/tows/webserviceawi.svc"); 
            var channelFactory = new ChannelFactory<WebServiceAWI>(binding, endpoint);
            var webService = channelFactory.CreateChannel();
            var user = new ARM_ARMS.User();
            user.UserName = await webService.EncryptValueAsync("username");
            user.Password = await webService.EncryptValueAsync("password12345");
            var response = await client.ClaimSearchAsync(user, "", "", 12345, ARM_ARMS.statuscode.NotSet, "");
       }

我在下面创建了这个通用类，因此我不必为来自同一个提供程序的 15 多个 url/web 服务中的每一个创建多个冗余方法，但是我在传递第二个参数时遇到了一些错误，这是一个接口（来自 Web 服务参考）。

public class WebService<T1, T2, T3> {
    private T1 _client;
    private T2 _interface;
    private T3 _user;

    public WebService(T1 wsClient, T2 wsInterface, T3 wsUser) {
        _client = wsClient;
        _interface = wsInterface;
        _user = wsUser;
    }

    public void CallWebService(string url, string userName, string password) {
        var client = _client; 
        var binding = new BasicHttpBinding(BasicHttpSecurityMode.Transport);
        var endpoint = new EndpointAddress(url); 
        var channelFactory = new ChannelFactory<_interface>(binding, endpoint);  
        var webService = channelFactory.CreateChannel();
        var user = _user;
        user.UserName = webService.EncryptValue(userName);
        user.Password = webService.EncryptValue(password);
        var response = client.ClaimSearch(user, "", "", 12345, GraceStatuscode.NotSet, "");
    }

}

我在下面这样调用它，但是当我创建实例时在参数中或在创建 ChannelFactory 的新实例时在方法中无法识别接口 WebServiceWRG 和 WebServiceAWI。我得到一条红线，上面写着“找不到命名空间名称_interface的类型”，在我创建新类实例的那一行中，每个接口参数都有一条红线，上面写着“'WebServiceWRG'是一种类型，它不是在给定的上下文中有效”

WebService someServiceA = new WebService(new WebServiceWRGClient(), WebServiceWRG, new GRACE_GRACES.User());
WebService someServiceB = new WebService(new WebServiceAWIClient(), WebServiceAWI, new ARM_ARMS.User());

更新 这是我在下面尝试过的，但仍然有错误： user.UserName = webService.EncryptValue(userName); //Two不包含'UserName'的def，T不包含EncryptValue的def

   public class Test {
        public void TestWebService() {
            var ws = new WebService<WebServiceWRG>();
            ws.SearchClaim(new WebServiceWRGClient(), new GraceUser(), "url", "userName", "password");
        }
    }

    public class WebService<T> { 
        public void SearchClaim<TOne, TTwo>(TOne entity1, TTwo entity2, string url, string userName, string password) 
            where TOne : class
            where TTwo : class
        {
            var client = entity1;
            var binding = new BasicHttpBinding(BasicHttpSecurityMode.Transport);
            var endpoint = new EndpointAddress(url);
            var channelFactory = new ChannelFactory<T>(binding, endpoint);
            var webService = channelFactory.CreateChannel();
            var user = entity2;
            user.UserName = webService.EncryptValue(userName); // username not found, encryptvalue not found
            user.Password = webService.EncryptValue(password); // passwordnot found, encryptvalue not found
            var response = client.ClaimSearch(user, "", "", 12345, GraceStatuscode.NotSet, ""); // claimsearch not found
        }
    }

Answer 1

让我们首先承认您所做的更改是正确的更改。避免代码重复很重要，可以显着提高代码质量。干得好！

这可能是朝着正确方向迈出的一步：

public class WebService<T1, T2, T3> {
    private T1 _client;
    private T3 _user;

    //No T2

    public WebService(T1 wsClient, T3 wsUser) {
        _client = wsClient;
        _user = wsUser;
        //No interface
    }

    public void CallWebService(string url, string userName, string password) {
        (...)
        var channelFactory = new ChannelFactory<T2>(binding, endpoint);   <---- use the T2 type
        (...)
    }
}

然后

var someServiceA = new WebService<WebServiceWRGClient, WebServiceWRG, Whatever_GRACE_GRACES_User()_returns_here>(new WebServiceWRGClient(), new GRACE_GRACES.User());

（请注意var，因为类型不是WebService而是WebService<X,Y,Z>）

下一步

我认为您不需要为客户和用户使用泛型，下一步可能是：

public class WebService<T> {
    private Baseclassofallclients _client;
    private UserTypeHere _user;


    public WebService( Baseclassofallclients wsClient, UserTypeHere  wsUser) {
        _client = wsClient;
        _user = wsUser;
        //No interface
    }

    public void CallWebService(string url, string userName, string password) {
        (...)
        var channelFactory = new ChannelFactory<T>(binding, endpoint);   <---- use the T type here
        (...)
    }

然后

var someServiceA = new WebService<WebServiceWRG>(new WebServiceWRGClient(), new GRACE_GRACES.User());
var someServiceB = new WebService<WebServiceAWI>(new WebServiceAWIClient(), new ARM_ARMS.User());
