个人使用的log4net配置

最近在项目中使用log4net，配置起来有点麻烦，在参考了网上的资料后，按自己喜好做了一份配置文件，保存在此，以备复制粘贴。（- -|）

在Config文件根下增加以下配置：

代码

如果是Web项目，新建一个Global.asax文件，并在Application_Start方法里增加：log4net.Config.DOMConfigurator.Configure();

如果是WinForm项目，打开AssemblyInfo.cs文件，并增加[assembly: log4net.Config.DOMConfigurator()]

一个辅助类：

代码

using System;
using System.Collections.Generic;
using log4net;

public enum LogLevel
{
    Debug,
    Info,
    Warning,
    Error,
    Fatal
}

/// <summary>
/// Summary description for LogHelper
/// </summary>
public class LogHelper
{
    private static readonly ILog log = LogManager.GetLogger("loginfo");

    private LogHelper()
    { }

    public static void Write(LogLevel level, string message)
    {
        Write(level, message, null, null);
    }

    public static void Write(LogLevel level, Exception e)
    {
        Write(level, null, null, e);
    }

    public static void Write(LogLevel level, string message, Exception e)
    {
        Write(level, message, null, e);
    }

    public static void Write(LogLevel level, string message, IDictionary<string, string> additionalInfo)
    {
        Write(level, message, additionalInfo);
    }

    public static void Write(LogLevel level, string message, IDictionary<string, string> additionalInfo, Exception e)
    {
        string formattedMessage;
        switch (level)
        {
            case LogLevel.Debug:
                if (log.IsDebugEnabled)
                {
                    formattedMessage = FormatOutputMessage(message, additionalInfo);
                    log.Debug(formattedMessage, e);
                }
                break;
            case LogLevel.Info:
                if (log.IsInfoEnabled)
                {
                    formattedMessage = FormatOutputMessage(message, additionalInfo);
                    log.Info(formattedMessage, e);
                }
                break;
            case LogLevel.Warning:
                if (log.IsWarnEnabled)
                {
                    formattedMessage = FormatOutputMessage(message, additionalInfo);
                    log.Warn(formattedMessage, e);
                }
                break;
            case LogLevel.Error:
                if (log.IsErrorEnabled)
                {
                    formattedMessage = FormatOutputMessage(message, additionalInfo);
                    log.Error(formattedMessage, e);
                }
                break;
            case LogLevel.Fatal:
                if (log.IsFatalEnabled)
                {
                    formattedMessage = FormatOutputMessage(message, additionalInfo);
                    log.Fatal(formattedMessage, e);
                }
                break;
            default:
                throw new ArgumentException(string.Format("type '{0}' not add to Write method", level));
        }
    }

    private static string FormatOutputMessage(string message, IDictionary<string, string> additionalInfo)
    {
        if (additionalInfo == null || additionalInfo.Count == 0)
            return message;

        System.Text.StringBuilder buffer = new System.Text.StringBuilder();
        if (!string.IsNullOrEmpty(message))
            buffer.AppendLine(message);
        foreach (KeyValuePair<string, string> kvp in additionalInfo)
            buffer.AppendLine(kvp.Key + " = " + kvp.Value);

        return buffer.ToString();
    }
}
