C# 输出字符串到文本文件中

写个博客记录下，方便以后使用：

    public class WriteHelper
    {
        public static void WriteFile(object data)
        {
            try
            {
                string path = $@"D:\TokenLog\day{DateTime.Now:yyyy-MM-dd}";
                var filename = $"TokenLog{DateTime.Now:yyyy-MM-dd HH}.txt";
                if (!Directory.Exists(path))
                    Directory.CreateDirectory(path);
                TextWriter tw = new StreamWriter(Path.Combine(path, filename), true); //true在文件末尾添加数据

                tw.WriteLine($"----产生时间：{DateTime.Now:yyyy-MM-dd HH:mm:ss}---------------------------------------------------------------------");

                tw.WriteLine(data.ToJsonStr());
                tw.Close();
            }
            catch (Exception e)
            {

            }
        }
    }

public static class Json
{
        /// <summary>
        /// 转成json字符串
        /// </summary>
        public static string ToJsonStr(this object obj)
        {
            return JsonConvert.SerializeObject(obj, new JsonSerializerSettings { ReferenceLoopHandling = ReferenceLoopHandling.Ignore });
        }

}
