应用程序不会在另一个线程中故意崩溃
本文关键字:故意 崩溃 线程 另一个 应用程序 | 更新日期: 2023-09-27 18:15:56
我试图在一段时间后崩溃我的控制台应用程序(这是由于我测试应用程序是否会在崩溃后自行启动)。遵循本教程)
我的这段代码是:
static class WebSocket
{
static int Main(string[] args)
{
Recovery.RegisterForAutostart();
Recovery.RegisterForRestart();
Test.Run();
// some more code
}
}
public static class Recovery
{
[Flags]
public enum RestartRestrictions
{
None = 0,
NotOnCrash = 1,
NotOnHang = 2,
NotOnPatch = 4,
NotOnReboot = 8
}
public delegate int RecoveryDelegate(RecoveryData parameter);
public static class ArrImports
{
[DllImport("kernel32.dll")]
public static extern void ApplicationRecoveryFinished(
bool success);
[DllImport("kernel32.dll")]
public static extern int ApplicationRecoveryInProgress(
out bool canceled);
[DllImport("kernel32.dll")]
public static extern int GetApplicationRecoveryCallback(
IntPtr processHandle,
out RecoveryDelegate recoveryCallback,
out RecoveryData parameter,
out uint pingInterval,
out uint flags);
[DllImport("KERNEL32.dll", CharSet = CharSet.Unicode, SetLastError = true)]
public static extern int GetApplicationRestartSettings(
IntPtr process,
IntPtr commandLine,
ref uint size,
out uint flags);
[DllImport("kernel32.dll")]
public static extern int RegisterApplicationRecoveryCallback(
RecoveryDelegate recoveryCallback,
RecoveryData parameter,
uint pingInterval,
uint flags);
[DllImport("kernel32.dll")]
public static extern int RegisterApplicationRestart(
[MarshalAs(UnmanagedType.BStr)] string commandLineArgs,
int flags);
[DllImport("kernel32.dll")]
public static extern int UnregisterApplicationRecoveryCallback();
[DllImport("kernel32.dll")]
public static extern int UnregisterApplicationRestart();
}
public class RecoveryData
{
string currentUser;
public RecoveryData(string who)
{
currentUser = who;
}
public string CurrentUser
{
get { return currentUser; }
}
}
// Restart after crash
public static void RegisterForRestart()
{
// Register for automatic restart if the application was terminated for any reason.
ArrImports.RegisterApplicationRestart("/restart",
(int)RestartRestrictions.None);
}
// Start app when PC starts
public static void RegisterForAutostart()
{
#if (!DEBUG)
RegistryKey key = Registry.CurrentUser.OpenSubKey("SOFTWARE''Microsoft''Windows''CurrentVersion''Run", true);
key.SetValue("websocket", @"c:'websocket'run.bat");
#endif
}
public static class Test
{
public static void Run()
{
crash();
}
static void crash()
{
double crashAfter = 1.5 * 60; // seconds
int secondsPassed = 0;
int waitSeconds = 1;
Console.WriteLine("'nCrash test startet, crash will occour in " + crashAfter + " seconds");
Timer timer = new Timer(
delegate (object seconds) {
secondsPassed += int.Parse(seconds.ToString());
if (secondsPassed > crashAfter)
{
Console.WriteLine("Crashing");
Environment.FailFast("Test - intentional crash."); // Error happens here
}
else
{
double timeUntilCrash = (crashAfter - secondsPassed);
Console.WriteLine("Time until crash = " + timeUntilCrash + " seconds");
}
},
waitSeconds,
TimeSpan.FromSeconds(waitSeconds),
TimeSpan.FromSeconds(waitSeconds));
}
}
当它要崩溃的时候,我得到这样的消息:
无法求值表达式,因为线程在某个点停止垃圾收集是不可能的,可能是因为代码优化。
未选中代码优化复选框。
我想这是因为它不在主线程中,如果是这种情况,我如何返回主线程。如果不是,原因是什么?
我基于你的代码创建了一个应用程序&当应用程序从命令行运行时,发现一切都像预期的那样运行-只有在Visual Studio调试器中重启不起作用
多亏PaulF我们才发现了问题。我在Debug
模式下进行测试,在Visual Studio之外的发布模式下运行应用程序解决了这个问题。下面的NullReferenceException
是由于重新启动时缺少命令行参数引起的。
