来源：百度知道 编辑：UC知道 时间：2024/05/17 03:07:29
dataTime提取的时间为
2009-08-33 8:32:2
如何把它转换为
200908338322

方法一：Convert.ToDateTime(string)
string格式有要求，必须是yyyy-MM-dd hh:mm:ss

方法二：Convert.ToDateTime(string, IFormatProvider)
DateTime dt;
DateTimeFormatInfo dtFormat = new System.GlobalizationDateTimeFormatInfo();
dtFormat.ShortDatePattern = "yyyy/MM/dd";
dt = Convert.ToDateTime("2011/05/26", dtFormat);

方法三：DateTime.ParseExact()
string dateString = "20110526";
DateTime dt = DateTime.ParseExact(dateString, "yyyyMMdd", System.Globalization.CultureInfo.CurrentCulture);
或者
DateTime dt = DateTime.ParseExact(dateString, "yyyyMMdd", System.Globalization.CultureInfo.InvariantCulture);

System.DateTime.Now.ToString("yyyyMMddHHmmss");

ToString("yyyyMMddHHmmss")

DateTime dt = Convert.ToDateTime("2009-08-33 8:32:2");
dt.ToString("yyyyMMddHHmmss");
