在我的解决方案资源管理器中,我已经为Windows服务BridgeWS
拖了一个项目,而另一个项目Vytru.Platform.Bridge.Configuration
有一个静态类SharedData.cs
我的问题:我想使用此静态属性SharedData.DeviceList
来获取BridgeWS
服务中的Device对象列表,但它总是等于null?
这是我的解决方案
我的静态类
中的一些代码public static class SharedData
{
public const string CONFIGURATION_XML_PATH = @"\Configuration.xml";
private static List<Device> _deviceList;
public static void Initialize()
{
APPLICATION_LOCAL_PATH = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
if (!string.IsNullOrEmpty(APPLICATION_LOCAL_PATH)) CONFIGURATION_FULL_PATH = APPLICATION_LOCAL_PATH + CONFIGURATION_XML_PATH;
_deviceList = new List<Device>();
_tempDeviceList = new List<Device>();
_deviceAgent = new DeviceManager();
_deviceAgent.Initialize();
}
public static bool AddToTempDeviceList(Device device)
{
if (_tempDeviceList != null)
{
if (!_deviceAgent.IsExist(device, true))
{
_tempDeviceList.Add(device);
return true;
}
}
return false;
}
public static bool UpdateFile()
{
_deviceList = _tempDeviceList;
return _deviceAgent.Save();
}
public static List<Device> DeviceList
{
get { return _deviceList; }
set { _deviceList = value; }
}
public static List<Device> TempDeviceList
{
get { return _tempDeviceList; }
set { _tempDeviceList = value; }
}
public static DeviceManager DeviceAgent
{
get { return _deviceAgent; }
set { _deviceAgent = value; }
}
}
感谢并抱歉我的英语不好。
答案 0 :(得分:1)
您可以先调用Initialize方法。如果不这样做,由于这部分代码
,属性将为null_deviceList = new List<Device>();
_tempDeviceList = new List<Device>();
_deviceAgent = new DeviceManager();
_deviceAgent.Initialize();
在BridgeWS中
SharedData.Initialize();
SharedData.TempDeviceList; // not null
SharedData.DeviceList; // not null
