winform全局捕获异常

[code]
public static void ExceptionControl()
{
//设置应用程序处理异常方式：ThreadException处理
Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);
//处理UI线程异常
Application.ThreadException += (sender, e) =>
{
var str = GetExceptionMsg(e.Exception, e.ToString());
var messageForm =new ErrorMessageForm();
messageForm.SetMessage(str);
var flg = FormIsShow(messageForm.Name);
if (flg) return;
messageForm.ShowDialog();
};
//处理非UI线程异常
AppDomain.CurrentDomain.UnhandledException += (sender, e)=>
{
var str = GetExceptionMsg(e.ExceptionObject as Exception, e.ToString());
var messageForm = new ErrorMessageForm();
messageForm.SetMessage(str);
var flg = FormIsShow(messageForm.Name);
if (flg) return;
messageForm.ShowDialog();
};

}
private static string GetExceptionMsg(Exception ex, string backStr)
{
var sb = new StringBuilder();
if (ex == null)
{
sb.AppendLine("errmsg：" + backStr);
}
else
{
if (ex.GetType().Name.ToLower() == "exception")
{
return ex.Message;
}
sb.AppendLine("msgtime：" + DateTime.Now);
sb.AppendLine("msgtype：" + ex.GetType().Name);
sb.AppendLine("callstack：" + ex.Message);
sb.AppendLine("untreated：" + ex.StackTrace);
}
return sb.ToString();
}
