要在程序关闭和电脑关闭时运行的代码

我有一个作为系统托盘应用程序运行的无表单应用程序。当计算机关闭或应用程序关闭时,我不得不运行代码。
这就是我目前拥有的
class sysTrayIcon
{
public sysTrayIcon()
{
AppDomain.CurrentDomain.ProcessExit += new EventHandler(exitCode);
SystemEvents.SessionEnding += new SessionEndingEventHandler(exitCode);
}
public void exitCode(object sender, EventArgs e)
{
contactCman appClosing = new contactCman();
bool didWeSuceed = appClosing.stampUserOut();
if (didWeSuceed == false)
{
MessageBox.Show("Stamp out function run returned fail!!");
}
else
{
MessageBox.Show("Stamp out function run returned success");
}
}
}
class contactCman
{
public Dictionary<string, string> getUrlResponse(string toDo)
{
var url = mainSiteUrl + "/" + apiFileName + "?" + "userid=" + userid + "&pw=" + pw + "&toDo=" + toDo;
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
WebHeaderCollection header = response.Headers;
var encoding = ASCIIEncoding.ASCII;
string responseText;
using (var reader = new System.IO.StreamReader(response.GetResponseStream(), encoding))
{
responseText = reader.ReadToEnd();
}
// key1=value1;key2=value2;key3=value3;
var responseData = responseText.Split(new[] { ';' }, StringSplitOptions.RemoveEmptyEntries)
.Select(part => part.Split('='))
.ToDictionary(split => split[0], split => split[1]);
return responseData;
}
public Dictionary<string, string> checkLastStamp()
{
string toDo = "getLastStamp";
Dictionary<string, string> urlResponse = getUrlResponse(toDo);
return urlResponse;
}
public bool stampUserOut()
{
Dictionary<string, string> usersLastStamp = checkLastStamp();
string valueOfKey;
if (usersLastStamp.TryGetValue("checkInOut", out valueOfKey) && (valueOfKey == "in"))
{
string toDo = "stampUserOut";
Dictionary<string, string> urlResponse = getUrlResponse(toDo);
if (urlResponse.TryGetValue("Message", out valueOfKey) && (valueOfKey == "Success!"))
{
return true;
}
else
{
return false;
}
}
else
{
return false;
}
}
}
我的问题是,当在visualstudio中通过调试器运行时,上面的代码可以正常工作(只在程序关闭的情况下进行测试)。如果我在外面运行,消息框永远不会出现。
我认为最好听ApplicationExit
事件。它将阻止应用程序实际退出,直到处理程序被执行:
static void Main()
{
Application.ApplicationExit += Application_ApplicationExit;
...
}
static void Application_ApplicationExit(object sender, EventArgs e)
{
MessageBox.Show("Exit!");
}
- 如果没有窗口,SessionEnding不会启动。看见http://msdn.microsoft.com/en-us/library/microsoft.win32.systemevents.sessionending%28v=vs.110%29.aspx
- ProcessExit只有2秒钟的运行时间。现在显示消息框或执行任何交互式操作都为时已晚:http://msdn.microsoft.com/en-us/library/system.appdomain.processexit%28v=vs.110%29.aspx
我认为你要么需要一个服务,让它在登录/注销后保持活力,要么你需要创建一个窗口,让你有一个消息泵。
