【问题描述】：

我需要在我的 Windows 窗体项目中反序列化来自 COM 端口的数据。但我不知道如何开始。我之前尝试过谷歌，但我发现的信息不适用于我的案例，也没有一个与 COM 端口相关。即将到来的数据有多个我不需要的字符。好吧，我尝试将我找到的一些解决方案调整到我的代码中，但它们都不起作用，我尝试这样做，它创建了文件，但它没有在其中放入任何数据。

            port = new SerialPort(comboBox1.Text,
                                  9600, Parity.None, 8, StopBits.One);
            port.DataReceived += new SerialDataReceivedEventHandler(DataReceivedHandler);
            port.Open();

            void DataReceivedHandler(object sender, SerialDataReceivedEventArgs e)
            {
                SerialPort sp = (SerialPort)sender;
                string indata = sp.ReadExisting().ToString();
                this.Invoke(new EventHandler(ShowData));
                this.Invoke(new EventHandler(Serialization));

                void ShowData(object sender, EventArgs e)
                {
                    dtBox.Text += indata;
                }

                void Serialization(object sender, EventArgs e) 
                { 
                dynamic json = Newtonsoft.Json.JsonConvert.SerializeObject(indata);
                StreamWriter w = new StreamWriter(@\"C:/temp/JSON_TEST.json\", true);
                w.WriteLine(json);
                w.Close();
                }
            }

来自 COM 端口的数据是这样的：

                     ------------------------------------------
                     Date :                   11:33  25/07/2022

                     ------------------------------------------
                                                   Total Amount
                                                          5445
                     -------------------------------------------

我也想忽略连字符。有人可以帮助我吗？

谢谢！

【解决方案1】：

一些伪代码在我的脑海中浮现。

List<YourThisThatTotalClass> ytttc = new List<YourThisThatTotalClass>();
bool startCollecting = false;

//Iterate through each line till you find a line starting with `This`
foreach(var line in json.Split(Environment.Newline))
{
   if (line.StartWith("This")){
       startCollecting = true;
   }
   else if (startCollecting && line.StartWith("--")){
       break;
   }
   if (startCollecting){ //Store each record in a class
       string[] vals = line.Split(new char[0], StringSplitOptions.RemoveEmptyEntries); //new char[0] or null will assume whitespace is the delimiter, with StringSplitOptions.RemoveEmptyEntries to be safe
       ytttc.Add(new YourThisThatTotalClass {vals[0], vals[1], vals[2]});  // the class has a Constructor with three input parameters. You may want to cast them to numbers and do validation they're valid values.
   }
}
