log4net 使用方法记录(在控件中直接打印log)

引用log4net

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
/// <summary>
/// UiLogEventArgs.cs
/// </summary>
namespace MainAppGree.Log
{
class UiLogEventArgs : EventArgs
{
public string Message { get; private set; }

public UiLogEventArgs(string message)
{
Message = message;
}
}
}
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using log4net.Appender;
using log4net.Core;
/// <summary>
/// UiLogAppender.cs
/// </summary>
namespace MainAppGree.Log
{
class UiLogAppender : AppenderSkeleton
{
public event EventHandler<UiLogEventArgs> UiLogReceived;

protected override void Append(LoggingEvent loggingEvent)
{
var message = RenderLoggingEvent(loggingEvent);
OnUiLogReceived(new UiLogEventArgs(message));
}

protected virtual void OnUiLogReceived(UiLogEventArgs e)
{
if (UiLogReceived != null)
{
UiLogReceived(this, e);
}
}
}
}

具体调用方法：

页面中有一个TextBox控件txtLog

#region 全局变量

public static readonly log4net.ILog Log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

#endregion

private void DlgRVTaskRun_Load(object sender, EventArgs e)
{
//日志
var hierarchy = LogManager.GetRepository() as Hierarchy;
var appenders = hierarchy.Root.Repository.GetAppenders();

foreach (var appender in appenders)
{
var uiLogAppender = appender as UiLogAppender;
if (uiLogAppender != null)
uiLogAppender.UiLogReceived += LogEventHandle;
}
}

private void LogEventHandle(object o, UiLogEventArgs e)
{
// 解决线程占用问题
if (txtLog.InvokeRequired)
{
txtLog.Invoke(new System.Action(() => { txtLog.AppendText(e.Message + "\r\n"); }));
}
else
{
txtLog.AppendText(e.Message + "\r\n");
}
}

Log.Info();
Log.Debug();
Log.Error();
