一个简单的C#文件日志组件

最近工作需要一个简单的文件日志组件，Log4net配置太麻烦，在网上找了点资料然后改进了一下。

主要代码如下：

private static void WriteLog(string message)
        {
            try
            {
                string rootPath = AppDomain.CurrentDomain.SetupInformation.ApplicationBase;
                if (!rootPath.EndsWith("\\"))
                {
                    rootPath += "\\";
                }

                string path = rootPath + "Log\\";
                if (!Directory.Exists(path))
                {
                    Directory.CreateDirectory(path);
                }

                string filePath = path + DateTime.Today.ToString("yyyy-mm-dd") + ".txt";

                if (!File.Exists(filePath))
                {
                    File.Create(filePath).Close();   
                }
          
                using (StreamWriter w = File.AppendText(filePath))
                {
                    w.WriteLine("\r\n");
                    w.WriteLine("{0} ", DateTime.Now.ToString(CultureInfo.InvariantCulture));
                    w.WriteLine(message);
                    w.Flush();
                    w.Close();
                }
             
            }
            catch (Exception ex)
            {

            }

        }
