大华 解码器上大屏代码事例

昨天上传了一个海康解码器视频上大屏的代码事例    因为最近也在弄大华的设备  所以也传一份事例  希望对大家有帮助  有问题或建议可私信我  

同样的  传调用代码  及结构定义

1.调用代码

                    }

                }
                //虚拟表中存在
                else if (loginRow.Count() > 0)
                {
                    //读取出注册设备返回的id
                    LoginID = int.Parse(loginRow[0]["LoginID"].ToString());
                }
                if (LoginID > 0)
                {
                    //查询解码器信息
                    DEV_DECODER_INFO lpdecoder_info = new DEV_DECODER_INFO();
                    bool ress = DHClient.DHQueryDecoderInfo(LoginID, out lpdecoder_info, 2000);

                    //添加视频上墙需要的设备信息
                    DEV_ENCODER_INFO lpencoder_info = new DEV_ENCODER_INFO();
                    lpencoder_info.byDecoderID = (byte)decoderID;

                    lpencoder_info.szDevIpEx = new byte[64];
                    lpencoder_info.szDevPwd = new byte[16];
                    lpencoder_info.szDevUser = new byte[16];
                    lpencoder_info.wDevPort = 37777;
                    lpencoder_info.nDevChannel = Convert.ToInt32(ip.Split(';')[1]);	//通道	
                    lpencoder_info.nStreamType = 0; //主码流
                    lpencoder_info.bDevChnEnable = 1;
                    lpencoder_info.byConnType = 0;	//TCP
                    lpencoder_info.byWorkMode = 0;	//直连

                    // System.Text.Encoding.Default.GetBytes(camip).CopyTo(lpencoder_info.szDevIpEx, 0);
                    System.Text.Encoding.Default.GetBytes(ip.Split(';')[0]).CopyTo(lpencoder_info.szDevIpEx, 0);
                    System.Text.Encoding.Default.GetBytes("admin").CopyTo(lpencoder_info.szDevPwd, 0);
                        System.Text.Encoding.Default.GetBytes("admin").CopyTo(lpencoder_info.szDevUser
                    //视频上墙
                    res = DHClient.DHSwitchDecTVEncoder(LoginID, decoderID, ref lpencoder_info, IntPtr.Zero);
                }

            }
            catch (Exception ex)
            {
                fmessage.MessageRecord(ex.Message);
            }
            //设置成功 返回1
            if (res > 0)
            {

                return 1;

            }
            //设置失败 返回0
            else
            {
                return 0;
            }
        }
程序中 注册的ip会被储存到一个DataTable中   所以 代码中会出现查询LoginID  亲测可用


2.结构体 及调用方法的声明
