加载DBC文件上位机程序内

由于程序中需要根据DBC文件来解析通讯数据，一个一个将DBC里的信号输入程序太麻烦了，且不同的设备DBC文件格式相同，但内容不同，为了程序方便解析同的设备的数据，下面以解析文本的形式将DBC文件自动加载至程序中；

    public class TestDeviceVModel
    {
        string NS_;
        string Memo_;
        bool IsNs = false;
        object CM_ = null;
        private DeviceModel ImpDBCFile()
        {
            List<string> _dbc = new List<string>();
            using (StreamReader _sr = new StreamReader(YiouConvert.GetOpenFilePath(), Encoding.Default))
            {
                string line;
                while ((line = _sr.ReadLine()) != null)
                {
                    line = line.TrimStart().Replace("  ", " "); ;

                    if (!string.IsNullOrWhiteSpace(line) && !line.StartsWith("//"))// 去掉空行和注释行
                    {
                        _dbc.Add(line);
                    }
                }
                _sr.Close();
            }
