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();
