**第一种方法**

string timeStr = "2019-08-28";

DateTime time= Convert.ToDateTime(timeStr);

**第二种：**

DateTimeFormatInfo timeForInfo = new DateTimeFormatInfo();

timeForInfo.ShortDatePattern = "yyyy/MM/dd";

string timeStr1 = "2018-09-08";

var time = Convert.ToDateTime(timeStr1, timeForInfo);

**第三种:**

string dateString = "20190526";

DateTime time = DateTime.ParseExact(dateString, "yyyyMMdd", System.Globalization.CultureInfo.CurrentCulture);
