从DateTime类型解析为字符串

Question

我试图将a DateTime和int属性转换为foreach循环中的字符串.我需要将存储在对象属性中的信息放入变量中,然后使用该信息使用StreamWriter写入文本文件.我不太确定我做错了什么. Parse带有此错误消息的红色下划线 -

错误2'字符串'不包含'Parse'的定义

这是我的代码 -

 public bool Save()
        {
            string appointStart;
            string appointLength;
            string appointDescription;

            foreach (Appointment appointment in appointments)
            {
                appointStart = string.Parse(appointment.Start);
                appointLength = string.Parse(appointment.Length);
                appointDescription = appointment.DisplayableDescription;

            }
            return true;
        }

谢谢

使用DateTime和Int32类的ToString()方法获取指定类型的字符串表示形式.一些ToString()方法提供重载来定义字符串值的格式.

foreach (Appointment appointment in appointments)
{
  appointStart = appointment.Start.ToString();
  appointLength = appointment.Length.ToString();
  appointDescription = appointment.DisplayableDescription;
}
