事件日志WriteEntry不会写入日志指定，而是应用程序日志 [英] EventLog WriteEntry does not write to designated log, but to Application log

问题描述

我有，我想B上的记录器通过MEF实例编写条目事件日志$ B $的应用程序。
我创建了一个派生类，要能先用它来执行日志初始化

I have an application where I want to write entries to event log The logger is instantiated through MEF. I created a derived class, to be able to perform the log initializations prior of using it.

我的代码如下：

public class WinEventLog : EventLog, ILogger
{
    private const string LOG_SourceName = "DataGen_Source";
    private const string LOG_SysLogName = "Pool_Log";

    private bool _isInitialized = false;

    public WinEventLog()
        : base()
    {
        Initialize();
    }

    public void LogMessage(MessageLevel level, string message)
    {
        WriteEntry(message, level.EventLogType());
    }

    public void LogMessage(string source, MessageLevel level, string message)
    {
        WriteEntry(source, message, level.EventLogType());
    }

    public void Initialize()
    {
        if (!_isInitialized)
        {
            this.BeginInit();
            this.EndInit();

            if (!System.Diagnostics.EventLog.SourceExists(LOG_SourceName))
            {
                System.Diagnostics.EventLog.CreateEventSource(
                    LOG_SourceName, LOG_SysLogName);
            }
            Source = LOG_SourceName;
            Log = LOG_SysLogName;
            _isInitialized = true;
        }
    }
} 

然而，logger不写入到我指定，Pool_Log日志，但在应用程序日志中。

However, the logger does not write into the log I specify, Pool_Log, but in Applications log.

任何想法，为什么出现这种情况？

Any idea why this happens?

修改

我EXACT引用从其他项目相同的成分，在这种情况下，它写道：正确的事件日志！

I referenced EXACT the same component from other project, and in this situation it wrote to the correct EventLog !!!

我明白！

感谢

推荐答案

您可以尝试以下方法：

evntSource = "MySource";

evntLog = "MyLog"; //This replace Application!
evntEvent = "My Event";
if (!EventLog.SourceExists(evntSource))
    EventLog.CreateEventSource(evntSource,evntLog); 

EventLog.WriteEntry(evntSource,evntEvent);
