问题描述
我正在尝试进行globalexceptionhandling，我已经尝试了3种方法来执行此操作，但是没有任何程序在程序中的某个地方引发异常
i'm trying to do globalexceptionhandling, i've already tried 3 methods to do this but nothing caught an exception thrown somewhere in the program
static void Main()
{
System.Windows.Forms.Application.EnableVisualStyles();
System.Windows.Forms.Application.SetCompatibleTextRenderingDefault(false);
System.Windows.Forms.Application.ThreadException +=
new System.Threading.ThreadExceptionEventHandler(Catch);
AppDomain.CurrentDomain.UnhandledException +=
new UnhandledExceptionEventHandler(Catch);
try
{
Application.Instance.Start();
}
catch (Exception ex)
{
StackTrace st = new StackTrace(ex, true);
StackFrame[] frames = st.GetFrames();
List<string> errorList = new List<string>();
IPHostEntry host = Dns.GetHostEntry(Dns.GetHostName());
foreach (var frame in frames)
{
errorList.Add("PC-Name: " + System.Environment.MachineName + "\nIP: " + host.AddressList.FirstOrDefault(x => x.AddressFamily == AddressFamily.InterNetwork) + "\nUser-Name: " + Application.Instance.LoggedInTester.LastName + " " + Application.Instance.LoggedInTester.FirstName + "\nDateiname: " + frame.GetFileName() + "\nMethode: " + frame.GetMethod().Name + "\nZeile: " + frame.GetFileLineNumber() + "\n\n");
}
SyslogMessage msg = new SyslogMessage(DateTime.Now, Facility.SecurityOrAuthorizationMessages1, Severity.Warning, host.AddressList.FirstOrDefault(x => x.AddressFamily == AddressFamily.InterNetwork).ToString(), "Prüfmittelüberwachung", errorList.FirstOrDefault());
SyslogUdpSender sender = new SyslogUdpSender("localhost", 514);
sender.Send(new SyslogMessage(DateTime.Now, Facility.SecurityOrAuthorizationMessages1, Severity.Warning, host.AddressList.FirstOrDefault(x => x.AddressFamily == AddressFamily.InterNetwork).ToString(), "Prüfmittelüberwachung", errorList.FirstOrDefault()), new SyslogRfc3164MessageSerializer());
}
}
static void Catch(object sender, System.Threading.ThreadExceptionEventArgs e)
{
StackTrace st = new StackTrace(e.Exception, true);
StackFrame[] frames = st.GetFrames();
List<string> errorList = new List<string>();
IPHostEntry host = Dns.GetHostEntry(Dns.GetHostName());
foreach (var frame in frames)
{
errorList.Add("PC-Name: " + System.Environment.MachineName + "\nIP: " + host.AddressList.FirstOrDefault(x => x.AddressFamily == AddressFamily.InterNetwork) + "\nUser-Name: " + Application.Instance.LoggedInTester.LastName + " " + Application.Instance.LoggedInTester.FirstName + "\nDateiname: " + frame.GetFileName() + "\nMethode: " + frame.GetMethod().Name + "\nZeile: " + frame.GetFileLineNumber() + "\n\n");
}
SyslogMessage msg = new SyslogMessage(DateTime.Now, Facility.SecurityOrAuthorizationMessages1, Severity.Warning, host.AddressList.FirstOrDefault(x => x.AddressFamily == AddressFamily.InterNetwork).ToString(), "Prüfmittelüberwachung", errorList.FirstOrDefault());
SyslogUdpSender send = new SyslogUdpSender("localhost", 514);
send.Send(new SyslogMessage(DateTime.Now, Facility.SecurityOrAuthorizationMessages1, Severity.Warning, host.AddressList.FirstOrDefault(x => x.AddressFamily == AddressFamily.InterNetwork).ToString(), "Prüfmittelüberwachung", errorList.FirstOrDefault()), new SyslogRfc3164MessageSerializer());
}
static void Catch(object sender, UnhandledExceptionEventArgs e)
{
StackTrace st = new StackTrace((Exception)e.ExceptionObject, true);
StackFrame[] frames = st.GetFrames();
List<string> errorList = new List<string>();
IPHostEntry host = Dns.GetHostEntry(Dns.GetHostName());
foreach (var frame in frames)
{
errorList.Add("PC-Name: " + System.Environment.MachineName + "\nIP: " + host.AddressList.FirstOrDefault(x => x.AddressFamily == AddressFamily.InterNetwork) + "\nUser-Name: " + Application.Instance.LoggedInTester.LastName + " " + Application.Instance.LoggedInTester.FirstName + "\nDateiname: " + frame.GetFileName() + "\nMethode: " + frame.GetMethod().Name + "\nZeile: " + frame.GetFileLineNumber() + "\n\n");
}
SyslogMessage msg = new SyslogMessage(DateTime.Now, Facility.SecurityOrAuthorizationMessages1, Severity.Warning, host.AddressList.FirstOrDefault(x => x.AddressFamily == AddressFamily.InterNetwork).ToString(), "Prüfmittelüberwachung", errorList.FirstOrDefault());
SyslogUdpSender send = new SyslogUdpSender("localhost", 514);
send.Send(new SyslogMessage(DateTime.Now, Facility.SecurityOrAuthorizationMessages1, Severity.Warning, host.AddressList.FirstOrDefault(x => x.AddressFamily == AddressFamily.InterNetwork).ToString(), "Prüfmittelüberwachung", errorList.FirstOrDefault()), new SyslogRfc3164MessageSerializer());
}
这是我已经尝试过的，没有发现
this is what i've already tried, nothing caught the exception.
，而且我没有使用标准的application.run方法，而是从一个单例类开始，对于每个视图（窗体），创建演示者并在其中创建视图
and i'm not using the standard application.run method, i'm using a singleton class to start from, where for every view(form) i have a presenter gets created in which the view gets created
有人知道如何使用此设置进行全局异常处理吗？
does anyone know how to do globalexception handling with this setup?
也，对不起我的英语不好
also, sorry for my bad english
最诚挚的问候
编辑：MVCE
namespace Application
{
static class Program
{
static void Main()
{
System.Windows.Forms.Application.EnableVisualStyles();
System.Windows.Forms.Application.SetCompatibleTextRenderingDefault(false);
System.Windows.Forms.Application.ThreadException +=
new System.Threading.ThreadExceptionEventHandler(Catch);
AppDomain.CurrentDomain.UnhandledException +=
new UnhandledExceptionEventHandler(Catch);
try
{
Application.Instance.Start();
}
catch (Exception ex)
{
//do some catching
}
}
static void Catch(object sender, System.Threading.ThreadExceptionEventArgs e)
{
//do some catching
}
static void Catch(object sender, UnhandledExceptionEventArgs e)
{
//do some catching
}
}
public class Application
{
private static Application _instance;
private Application()
{
}
public static Application Instance
{
get
{
return _instance ?? (_instance = new Application());
}
}
internal void Start()
{
StartOverviewWindow();
}
private void StartOverviewWindow()
{
throw new Exception();
}
}
}
推荐答案
作为一个快速答案（因为我找不到所有这些的重复项），来处理
As a quick answer (because I can't find duplicates for all of those), to handle
抛出异常的地方
an exception thrown somewhere
您必须处理以下事件：
Application.ThreadException += ...
Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);
AppDomain.CurrentDomain.UnhandledException += ...
// tasks exceptions, add in app.config:
// <runtime>
// <ThrowUnobservedTaskExceptions enabled="true"/>
// </runtime>
TaskScheduler.UnobservedTaskException += ...
之间的差Application.ThreadException 和 AppDomain.CurrentDomain.UnhandledException 参见这个。
