Modbus设备信息加载的实现方式有很多种，这里讨论一种实现，思路比代码重要，具体类大家可以按自己的要求构建。

Load窗体事件中：

GlobalProperties.Device = LoadDevice(GroupPath, DevicePath, VariablePath);

具体的实现为， 这样所有的设备，参数

        /// <summary>/// 添加设备信息/// </summary>/// <param name="groupPath"></param>/// <param name="devicePath"></param>/// <param name="variablePath"></param>/// <returns></returns>private Device LoadDevice(string groupPath, string devicePath, string variablePath){if (!File.Exists(groupPath)){GlobalProperties.AddLog(1, "通信组文件不存在");return null;}List<Group> GpList = LoadGroup(groupPath, variablePath);if (GpList != null && GpList.Count > 0){try{return new Device(){IPAddress = IniHelper.ReadDefult("设备参数", "IP地址", "", devicePath),Port = Convert.ToInt32(IniHelper.ReadDefult("设备参数", "端口号", "502", devicePath)),CurrentRecipe = IniHelper.ReadDefult("配方参数", "当前配方", "", devicePath),GroupList = GpList,};}catch (Exception ex){GlobalProperties.AddLog(1, "通信组加载失败:" + ex.Message);return null;}}else{return null;}}

通信组及通信变量解析：

/// <summary>
/// 通信组及通信变量解析
/// </summary>
/// <param name="groupPath"></param>
/// <param name="variablePath"></param>
/// <returns></returns>
private List<Group> LoadGroup(string groupPath, string variablePath)
{//判断文件是否存在if (!File.Exists(groupPath)){GlobalProperties.AddLog(1, "通信组文件不存在");return null;}if (!File.Exists(variablePath)){GlobalProperties.AddLog(1, "通信变量文件不存在");return null;}//解析通信组List<Group> GpList = null;try{GpList = MiniExcel.Query<Group>(groupPath).ToList();}catch (Exception ex){GlobalProperties.AddLog(1, "通信组加载失败:" + ex.Message);return null;}//解析变量组,把variable添加到每个group中List<Variable> VarList = null;try{VarList = MiniExcel.Query<Variable>(variablePath).ToList();}catch (Exception ex){GlobalProperties.AddLog(1, "通信变量加载失败:" + ex.Message);return null;}if (VarList != null && GpList != null){foreach (var group in GpList){group.VarList = VarList.FindAll(c => c.GroupName == group.GroupName).ToList();}return GpList;}else{return null;}
}
