.net调用动态库NationECCode.dll使用电子凭证二维码解码接口

C#.net调用示例代码：

        [DllImport("NationECCode.dll", CallingConvention = CallingConvention.StdCall)]
        public static extern void NationEcTrans(string url, string input, IntPtr output);

        public static string inOut(string url, string input)
        {
            IntPtr outPut = System.Runtime.InteropServices.Marshal.AllocHGlobal(2048);
            NationEcTrans(url, input, outPut);
            string retStr = System.Runtime.InteropServices.Marshal.PtrToStringAnsi(outPut);
            System.Runtime.InteropServices.Marshal.FreeHGlobal(outPut);
            return retStr;
        }

        static void Main(string[] args)
        {
            string toUrl = "http://172.16.33.247/localcfc/api/hsecfc/localQrCodeQuery";
            string inPut = "{\"data\":{\"businessType\":\"01203\",\"deviceType\":\"\",\"officeId \":\"32760\",\"officeName\":\"123\",\"operatorId\":\"test001\",\"operatorName\":\"456\",\"orgId\":\"35020319001\"},\"orgId\":\"35020319001\",\"transType\":\"ec.query\"}";
            
            string outPut= inOut(toUrl, inPut);
            Console.WriteLine("出参:"+ outPut);

            Console.Read();
        }

测试解码正常。
