读取 EventLog C# 错误

发布于 2024-08-28 14:00:36 字数 464 浏览 1 评论 0原文

我的 ASP.NET 应用程序中有一段用 C# 编写的代码，它试图读取事件日志，但它返回一个错误。

EventLog aLog = new EventLog();
aLog.Log = "Application";
aLog.MachineName = ".";  // Local machine

foreach (EventLogEntry entry in aLog.Entries)
{
 if (entry.Source.Equals("tvNZB"))
     Label_log.Text += "<p>" + entry.Message;
}

它返回的条目之一是“无法找到源“tvNZB”中事件 ID“0”的描述。本地计算机可能没有必要的注册表信息或消息 DLL 文件来显示该消息，或者您可能没有权限访问它们。以下信息是事件的一部分：“服务已成功启动。”

我只想要“服务已成功启动”。有什么想法吗？

原文

I have this code in my ASP.NET application written in C# that is trying to read the eventlog, but it returns an error.

EventLog aLog = new EventLog();
aLog.Log = "Application";
aLog.MachineName = ".";  // Local machine

foreach (EventLogEntry entry in aLog.Entries)
{
 if (entry.Source.Equals("tvNZB"))
     Label_log.Text += "<p>" + entry.Message;
}

One of the entries it returns is "The description for Event ID '0' in Source 'tvNZB' cannot be found. The local computer may not have the necessary registry information or message DLL files to display the message, or you may not have permission to access them. The following information is part of the event:'Service started successfully.'"

I only want the 'Service started successfully'. Any ideas?

试试这个:)

        EventLog aLog = new EventLog();
        aLog.Log = "Application";
        aLog.MachineName = ".";  // Local machine

        string message = "\'Service started\'";

        foreach (EventLogEntry entry in aLog.Entries)
        {
            if (entry.Source.Equals("tvNZB")
             && entry.EntryType == EventLogEntryType.Information)
            {
                if (entry.Message.EndsWith(message))
                {
                    Console.Out.WriteLine("> " + entry.Message);
                    //do stuff
                }
            }
        }

它适用于 Win XP 家庭版。该消息在另一个操作系统上可能有所不同。
最好的方法：通过 System.Diagnostics.Trace.Write 转储 entry.Message 并查看确切的消息。

希望一切顺利:)

Try this :)

        EventLog aLog = new EventLog();
        aLog.Log = "Application";
        aLog.MachineName = ".";  // Local machine

        string message = "\'Service started\'";

        foreach (EventLogEntry entry in aLog.Entries)
        {
            if (entry.Source.Equals("tvNZB")
             && entry.EntryType == EventLogEntryType.Information)
            {
                if (entry.Message.EndsWith(message))
                {
                    Console.Out.WriteLine("> " + entry.Message);
                    //do stuff
                }
            }
        }

It works on Win XP home. The message might be different on another OS.
Best way: dump entry.Message by System.Diagnostics.Trace.Write and see the exact message.

Hope it works smoothly :)
