我有处理应用程序错误的代码（可在 Internet 上找到）。我在事件日志中写道。
void Application_Error(object sender, EventArgs e)
{
Exception myError = null;
if (HttpContext.Current.Server.GetLastError() != null)
{
string eventLog = "MySite";
string eventSource = "www.mysite.com";
string myErrorMessage = "";
myError = Server.GetLastError();
while (myError.InnerException != null)
{
myErrorMessage += "Message\r\n" +
myError.Message.ToString() + "\r\n\r\n";
myErrorMessage += "Source\r\n" +
myError.Source + "\r\n\r\n";
myErrorMessage += "Target site\r\n" +
myError.TargetSite.ToString() + "\r\n\r\n";
myErrorMessage += "Stack trace\r\n" +
myError.StackTrace + "\r\n\r\n";
myErrorMessage += "ToString()\r\n\r\n" +
myError.ToString();
myError = myError.InnerException;
}
if (EventLog.SourceExists(eventSource))
{
EventLog myLog = new EventLog(eventLog);
myLog.Source = eventSource;
myLog.WriteEntry("An error occurred in the Web application "
+ eventSource + "\r\n\r\n" + myErrorMessage,
EventLogEntryType.Error);
}
}
}
这是事件日志中的行：
Type Date Time Source Event Category
Error 03.04.2012 16:44:41 www.mysite.com 0 "An error occurred in the Web application www.mysite.com
"

Error 03.04.2012 16:42:54 www.mysite.com 0 "An error occurred in the Web application www.mysite.com
"
Error 03.04.2012 16:37:27 www.mysite.com 0 "An error occurred in the Web application www.mysite.com
"
正如您所指出的，错误大约每秒钟发生一次。但是关于错误的信息是空的。
这段代码有什么问题？
谢谢。
