C#强转DateTime类型

方式一：Convert.ToDateTime(string)

注意：string格式有要求，必须是yyyy-MM-dd hh:mm:ss

方式二：Convert.ToDateTime(string, IFormatProvider)

 DateTimeFormatInfo dtFormat = new System.GlobalizationDateTimeFormatInfo();
 dtFormat.ShortDatePattern = "yyyy/MM/dd";
 DateTime  dt = Convert.ToDateTime("2022/10/01", dtFormat);

方式三：DateTime.ParseExact()

string dateString = "20221001";
DateTime dt = DateTime.ParseExact(dateString, "yyyyMMdd", System.Globalization.CultureInfo.CurrentCulture);
