试试下面的代码

Month = Date = DateTime.Now.Month.ToString();   
Year = DateTime.Now.Year.ToString(); 
ViewBag.Today = System.Globalization.CultureInfo.InvariantCulture.DateTimeFormat.GetMonthName(Int32.Parse(Month)) + Year;

还可以使用XmlConvert。ToDateString

var dateStr = "2011-03-21 13:26";
var parsedDate = XmlConvert.ToDateTime(dateStr, "yyyy-MM-dd hh:mm");

最好指定日期类型，代码为:

var anotherParsedDate = DateTime.ParseExact(dateStr, "yyyy-MM-dd hh:mm", CultureInfo.InvariantCulture, DateTimeStyles.AssumeUniversal);

试试下面的代码

Month = Date = DateTime.Now.Month.ToString();   
Year = DateTime.Now.Year.ToString(); 
ViewBag.Today = System.Globalization.CultureInfo.InvariantCulture.DateTimeFormat.GetMonthName(Int32.Parse(Month)) + Year;

DateTime。DateTime, Format, DateTimeFormatInfo。InvariantInfo DateTimeStyles。allowtrailingwhite)

例如:

DateTime。ParseExact("2011-03-21 13:26"， "yyyy-MM-dd hh:mm"， DateTimeFormatInfo. "InvariantInfo DateTimeStyles。AllowLeadingWhite | DateTimeStyles.AllowTrailingWhite;

var dateStr = @"2011-03-21 13:26";
var dateTime = DateTime.ParseExact(dateStr, "yyyy-MM-dd HH:mm", CultureInfo.CurrentCulture);

将一个人类可读的字符串的值放入.NET DateTime中，代码如下:

DateTime.ParseExact("April 16, 2011 4:27 pm", "MMMM d, yyyy h:mm tt", null);
