如何全局捕捉Winform程序异常呢，当然是从程序启动入口的Program类下的Main()方法定义了，下面看下这个类怎么写的吧
static class Program
{
static string RunFormFullName
{
get
{
string setRunFormFullName = CIPACE.Sys.Configuration.RunFormFullName;
if (setRunFormFullName == null)
setRunFormFullName = DigiForm.SETRUNFORMFULLNAME; return setRunFormFullName;
}
}
/// <summary>
/// 应用程序的主入口点。
/// </summary>
public static ApplicationContext context; [STAThread]
private static void Main()
{
try
{
//处理未捕获的异常
Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);
//处理UI线程异常
Application.ThreadException += Application_ThreadException;
//处理非UI线程异常
AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException; var aProcessName = Process.GetCurrentProcess().ProcessName;
if ((Process.GetProcessesByName(aProcessName)).GetUpperBound() > )
{
MessageBox.Show(@"系统已经在运行中，如果要重新启动，请从进程中关闭...", @"系统警告", MessageBoxButtons.OK, MessageBoxIcon.Asterisk);
}
else
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
context = new ApplicationContext();
Application.Idle += Application_Idle; //注册程序运行空闲去执行主程序窗体相应初始化代码
Application.Run(context);
}
}
catch (Exception ex)
{
LogNet.Log.WriteLog("Main", ex);
MessageBox.Show("系统出现异常：" + (ex.Message + " " + (ex.InnerException != null && ex.InnerException.Message != null && ex.Message != ex.InnerException.Message ? ex.InnerException.Message : ""))+",请重启程序。"); DigiForm digiForm = new DigiForm();
digiForm.UpdateAppSettings(DigiForm.RUNFORMFULLNAME, DigiForm.LOGINFORMFULLNAME);
}
} private static void Application_Idle(object sender, EventArgs e)
{
Application.Idle -= Application_Idle;
if (context.MainForm == null)
{
Form form = new LoginForm();
context.MainForm = form;
form.Show();
}
} private static void Application_ThreadException(object sender, ThreadExceptionEventArgs e)
{
var ex = e.Exception;
if (ex != null)
{
LogNet.Log.WriteLog("Application_ThreadException", ex);
} MessageBox.Show("系统出现异常：" + (ex.Message + " " + (ex.InnerException != null && ex.InnerException.Message != null && ex.Message != ex.InnerException.Message ? ex.InnerException.Message : "")));
} private static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
var ex = e.ExceptionObject as Exception;
if (ex != null)
{
LogNet.Log.WriteLog("CurrentDomain_UnhandledException", ex);
} MessageBox.Show("系统出现异常：" + (ex.Message + " " + (ex.InnerException != null && ex.InnerException.Message != null && ex.Message != ex.InnerException.Message ? ex.InnerException.Message : "")));
} }
