所以我一直在用 C# 摆弄 Web 响应和请求，当我尝试运行该程序时遇到了问题。我的其中一行代码：

var response = await httpClient.SendAsync(request);

方法制作中需要异步

private static void Main(string[] args)

进入

private static async Task Main(string[] args)

看起来没有错误，但是在构建时，我收到错误消息：

程序不包含适合入口点的静态“Main”方法。

这是我的代码

private static async Task Main(string[] args)
        {

            try
            {
                /*HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://billing.roblox.com/v1/gamecard/redeem");
                            request.Method = "POST";
                            request.ContentType = "application/json";
                            request.Accept = "application/json";
                            JsonExtensionDataAttribute data = new JsonExtensionDataAttribute();
                            data = '3335996838'*/
                using (var httpClient = new HttpClient())
                {
                    using (var request = new HttpRequestMessage(new HttpMethod("POST"), "https://billing.roblox.com/v1/gamecard/redeem"))
                    {
                        request.Headers.TryAddWithoutValidation("Accept", "application/json");

                        request.Content = new StringContent("3335996838", Encoding.UTF8, "application/json"); …
