我的【XF.net】常用工具库

【XF.net】库是我这些年工作中，将常见的功能进行一个简单封装的工具库，里面涵盖：通用函数功能如（对象深拷贝，加密/解密/正反序列化/压缩解压等），及相关工控行业的功能如（DBC文件读取，通讯报文解析，BMS程序刷写，数据库访问等）。如果在您日常中代码开发中涉及到这些当面，那就可以尝试使用这个库，这样有些细节您就不需要关心了，下面我就根据这两个方面简单的举例说明使用方法：

首先在Visual Studio的NuGet管理器中安装【XF.net】库：

　　1.通讯协议报文：

　　　　1.1.DBC文件读取：

 原始DBC内容：

BO_ 123 VehicleStatus: 8 ECU1
 SG_ Speed : 0|16@0+ (0.1,0) [0|255] "km/h" ECU1
 SG_ EngineRPM : 16|16@0+ (1,0) [0|65535] "RPM" ECU1
 SG_ FuelLevel : 32|8@0+ (0.5,0) [0|100] "%" ECU1
 CM_ BO_ 123 "车辆状态消息"
 CM_ SG_ Speed "车速信号"
 CM_ SG_ EngineRPM "发动机转速信号"
 CM_ SG_ FuelLevel "燃油液位信号"

BO_ 456 DiagnosticData: 8 ECU2
 SG_ ErrorCode : 0|32@0+ (1,0) [0|4294967295] "无符号" ECU2
 CM_ BO_ 456 "诊断数据消息"
 CM_ SG_ ErrorCode "错误代码信号"

读取DBC文件：

private static void ReadDbcFile()
{
    System.Text.Encoding encoding = System.Text.Encoding.UTF8;

    var mesgList = new ReadDbcFile().OpenFileReadMess(@"D:\测试.dbc", string.Empty,ref encoding,true ,out var strDbc);   //读取测试.dbc文件,只需要1行代码搞定

    //为了方便查看，将读取到的DCB文件中的信号配置使用JSON打印出来：
    Console.WriteLine(XF.net.Base.Json.JsonExtensions.ToJson(mesgList, false, true));
}

运行效果：

　　　1.2.DBC报文解析：

/// <summary>
/// 解析DBC报文参数
/// </summary>
private static void DbcParamAnalysis()
{
    var testMsg = new MessageModel() { ID = 123, Data = [1, 2, 3, 4, 5, 6, 7, 8] }; //测试模拟报文

    var dicParamData = new ConcurrentDictionary<string, double>();
    if (DbcSingleAnalysis.AnalysisDbcSignal(new ReadDbcFile().OpenFileReadMess(@"D:\测试.dbc", string.Empty, ref _encoding, true, out _).First().SignalParamList, testMsg, dicParamData))
    {
        ///解析成功，打印解析后参数值：
        foreach (var ps in dicParamData)
        {
            Console.WriteLine($"参数名称：{ps.Key}，数值={ps.Value}");
        }
    }
}

运行效果：

　　　1.3.自定义报文参数解析（可以支持跨bit解析）：

/// <summary>
/// 自定义报文参数解析
/// </summary>
public static void MsgParamAnalysis()
{
    var bys = new byte[] { 1, 2, 3, 4, 5, 6, 7, 8 };

    Console.WriteLine($"无符号解析报文，从第9bit开始，长度为12bit，系数为1，偏移量为0，小端，解析后值={ProtocolAnalysis.AnalysisBit(bys, 9, 12, 1, 0, false)}");
    Console.WriteLine($"有符号解析报文，从第9bit开始，长度为12bit，系数为1，偏移量为0，大端，解析后值={ProtocolAnalysis.AnalysisSignedBit(bys, 9, 12, 1, 0, true)}");
    Console.WriteLine($"Float解析报文，从第9bit开始，长度为12bit，系数为1，偏移量为0，小端，解析后值={ProtocolAnalysis.AnalysisSignedBit(bys, 9, 32, 1, 0, false)}");
    Console.WriteLine($"Double解析报文，从第9bit开始，长度为12bit，系数为1，偏移量为0，小端，解析后值={ProtocolAnalysis.AnalysisSignedBit(bys, 0, 64, 1, 0, false)}");
}

运行效果：

　　1.4.更新报文内容：

/// <summary>
/// 更新报文数据
/// </summary>
private static void UpdateMsgData()
{
    var bys = new byte[] { 1, 2, 3, 4, 5, 6, 7, 8 };
    Console.WriteLine($"更新【前】报文：{BitConverter.ToString(bys)}");

    ProtocolAnalysis.IntConvertBit(bys, 6, 10, 66, true);
    Console.WriteLine($"从第6bit开始更新，长度为10bit，更新值是66，更新【后】报文：{BitConverter.ToString(bys)}");
}

运行后效果：

　　1.5.BMS/ECU基于UDS程序刷写：
