C# 输出字符串到文本文件中的实现代码

  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 });    }}
