晚上关于删除的日志文件主要有 https://blog.csdn.net/hellolib/article/details/78316253， 其实我这里的实现方式和他差不多，不过我这里不用配置时间， 直接写死 删除10天以前的日志数据，
static ILog _log = null;
static object lockHelper = new object();
private ILog GetLog()
{
if (null == _log)
{
lock (lockHelper)
{
if (null == _log)
{
StackTrace stackTrace = new StackTrace(this._skipFrames);
StackFrame stackFrame = stackTrace.GetFrame(0);
MethodBase methodBase = stackFrame.GetMethod();
// ApplicationRollingFile在.config文件中配置的名称
_log = LogManager.GetLogger("ApplicationRollingFile");
Task.Run(()=> {
var apps = _log.Logger.Repository.GetAppenders();
if (apps.Length <= 0)
{
return;
}
var now = DateTime.UtcNow.AddDays(-10);
foreach (var item in apps)
{
if (item is RollingFileAppender)
{
RollingFileAppender roll = item as RollingFileAppender;
var dir = Path.GetDirectoryName(roll.File);
var files = Directory.GetFiles(dir, "*.txt");
//var sample = "log.txt2017-10-23.txt";
foreach (var filePath in files)
{
var file = new FileInfo(filePath);
if (file.CreationTimeUtc < now) {
try
{
file.Delete();
}
catch (Exception)
{
}
}
}
}
}
});
}
}
}
return _log;
}
