用.NET将字符串“dd month_full_name year”转换为字符串“yyyy/mm/dd”

您将希望以准确的格式分析日期,而不是依赖区域性

DateTime.ParseExact(dateString, "d MMMM yyyyy", CultureInfo.InvariantCulture).ToString("yyyy/MM/dd");

Console.WriteLine(DateTime.Parse("1 February 2001").ToString("yyyy/MM/dd"));

这是假设你一直在美国文化中。

 string in = "1 February 2001";
    DateTime dt = DateTime.Parse(in);
    string out = dt.ToString("yyyy/MM/dd");

datetime out=datetime.parse(in);

 DateTime dt = 
  Convert.ToDateTime("1 February 2001", new CultureInfo("2001/02/01"));
