                resp.ContentLength64 = buffer.Length;

                using Stream ros = resp.OutputStream;
                ros.Write(buffer, 0, buffer.Length);
            }
            Pause();
        }
    }
}

PS.

    01.克服要能任意IP都可監聽(錯誤訊息:httplistener access denied)，要賦予EXE能以系統管理員身分執行(UAC/盾牌)[Windows 權限]
    02.使用curl.exe/一般瀏覽器 測試會動
    03.可以用來製作簡易web api server
