c# - 在方法中传递和返回两个不同的泛型类

Question

现在我正在为 Generic1 使用 T，但是当我传入 sPayload 时出现错误是可以理解的，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和硬编码传入的潜在类型。我只是不确定如何去做。

您需要在声明中指定这两种类型:

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;
    }
}
