在方法中传递和返回两个不同的泛型类

Question

现在，我在Generic1上使用T ，但是可以理解的是，当我传入sPayload时遇到错误，因为我不确定如何指定第二个泛型类型。

public static Generic1 SendReceive<Generic1>(string sUrl, Generic2 sPayload)
{
    using(WebClient webclient = new WebClient())
    {
        webclient.Headers[HttpRequestHeader.ContentType] = "application/json";
        string response = webclient.UploadString(sUrl, JsonConvert.SerializeObject(sPayload));
        Generic1 parsedResponse = JsonConvert.DeserializeObject<Generic1>(response);
        return parsedResponse;
    }
}

我想避免使用条件语句并对即将传入的潜在类型进行硬编码。我只是不确定如何执行此操作。

Answer 1

您需要在声明中同时指定两种类型：

public static TResult SendReceive<TResult, TPayLoad>(string sUrl, TPayLoad sPayload)
{
    using(WebClient webclient = new WebClient())
    {
        webclient.Headers[HttpRequestHeader.ContentType] = "application/json";
        string response = webclient.UploadString(sUrl, JsonConvert.SerializeObject(sPayload));
        TResult parsedResponse = JsonConvert.DeserializeObject<TResult>(response);
        return parsedResponse;
    }
}

Answer 2

您可以通过用逗号分隔多个通用类型来指定它们

public static TResponse SendReceive<TRequest,TResponse>(string sUrl, TRequest sPayload)
{
   ....
}

Answer 3

您可以使用这种方式添加多个参数

public static T1 SendReceive<T1,T2,...Tn>(string sUrl, TRequest sPayload)
{
   //TODO Code
}

然后你可以这样称呼它

className.SendResponse<Class1, Class2,...Classn>(...);
