通过测试，发现验证是否要保存日志验证很慢，我试了好多种方法验证都还是不理想，所以把删除了，只能按需调用方法就行了，示例代码如下：

测试代码：

Utils.Logger.Instance.Init();            var sw = new Stopwatch();            sw.Start();            for (int i = 0; i < 10000; i++)            {                Utils.Logger.Instance.Debug("Logger测试");            }            sw.Stop();            Console.WriteLine("Logger 日志循环10000次，总耗时：" + sw.ElapsedMilliseconds);            sw = new Stopwatch();            sw.Start();            Parallel.For(0, 100, (i) =>            {                for (int j = 0; j < 100; j++)                {                    Utils.Logger.Instance.Debug("Logger测试");                }            });            sw.Stop();            Console.WriteLine("Logger 并行循环10000次，总耗时：" + sw.ElapsedMilliseconds);            Console.ReadKey();

快是快多了，但是要是按需写入日志就没有办法实现了，有时间在研究一下，怎么验证效率才会更高
