C#生成anb文件

Posted 2022-12-15 穆雄雄

今天我们来看看C#中如何生成anb文件。

这个anb文件本来是要对接别的平台的，人家提供给我们一个协议，然后通过程序来生成，然后对方会根据生成的anb文件进行解析，然后得到心电图啥的。

代码如下：

private void createFileBtn_Click(object sender, EventArgs e)

string fileName = “demo.anb”;
string filePath = @“D:” + fileName;
bool isFile = Directory.Exists(filePath);
if (isFile)
//
// Directory.CreateDirectory(filePath);
//
//else

Directory.Delete(filePath);
// Directory.CreateDirectory(filePath);

string txtJson = this.txtJson.Text;
if (string.IsNullOrWhiteSpace(txtJson))

MessageBox.Show(“请输入对应的字符串”);
return;

string fileOtherPath = this.txtFilePath.Text;
if (string.IsNullOrWhiteSpace(fileOtherPath))

MessageBox.Show(“请输入ECG文件路径”);
return;

// byte[] txtByte = Encoding.Unicode.GetBytes(txtJson);
FileStream fs = new FileStream(fileOtherPath, FileMode.Open, FileAccess.Read);
byte[] fsEcg = new byte[fs.Length];
fs.Read(fsEcg, 0, Convert.ToInt32(fs.Length));
fs.Close();

        var allVoltageText = File.ReadAllText(fileOtherPath);
        allVoltageText = allVoltageText.Trim('"');
        var allVoltageValues = allVoltageText.Split(',').Select(t => short.Parse(t)).ToArray();

        //List<byte> list = new List<byte>();
        //list.AddRange(txtByte);
        //list.AddRange(fsEcg);
        //byte[] data = list.ToArray();
        //Stream input = new MemoryStream(data);
        //FileStream file = new FileStream(filePath, FileMode.OpenOrCreate);
        //BinaryWriter binaryWriter = new BinaryWriter(file);
        //for (int i = 0; i < txtByte.Length; i++)
        //
        //    binaryWriter.Write(txtByte[i]);
        //
        //for (int i = 0; i < fsEcg.Length; i++)
        //
        //    binaryWriter.Write(fsEcg[i]);
        //
        //char[] cChar = Encoding.ASCII.GetChars(txtByte);
        //binaryWriter.Write(cChar);
        //char[] ecgChar = Encoding.ASCII.GetChars(fsEcg);
        //binaryWriter.Write(ecgChar);
        //binaryWriter.Flush();
        //binaryWriter.Close();
        //file.Close();
        Stream stream = new FileStream(filePath, FileMode.OpenOrCreate);



        //int count = fsEcg.Length >> 1;
        //short[] dest = new short[count];
        //for (int i = 0; i < count; i++)
        //
        //    dest[i] = (short)(fsEcg[i * 2] << 8 | fsEcg[2 * i + 1] & 0xff);
        //

        Write(stream, txtJson, allVoltageValues);
        stream.Dispose();

        public static bool Write(Stream stream, string header, short[] leadDatas)
        
            BinaryWriter bw = new BinaryWriter(stream);
            try
            
                byte[] headerBuffer = Encoding.UTF8.GetBytes(header);
                bw.Write(headerBuffer.Length);
                bw.Write(headerBuffer);
                for (int i = 0; i < leadDatas.Length; i++)
                
                    bw.Write(leadDatas[i]);
                
                //if (header.IsTimeOrder)
                //

                //            bw.Write(convertData(leadDatas[j][i]));
                //        
                //    
                //
                //else
                //
                //    foreach (short[] leadData in leadDatas)
                //    
                //        foreach (short data in leadData)
                //        
                //            bw.Write(convertData(data));
                //        
                //    
                //
            
            catch (Exception ex)
            
                Console.WriteLine(ex);
                return false;
            
            finally
            
                bw.Flush();
            

            return true;
        

    

生成的如下图所示：
