Hi,

I have a string like below which is I am converting to datetime format. I tried in below way. Is there any other way to do it. Expected outcome of string after formatting should be like yyyy-MM-dd hh:mm:ss ms.

            StringBuilder myStringBuilder = new StringBuilder("20180215031530000");
            myStringBuilder = myStringBuilder.Insert(4, "-");
            myStringBuilder = myStringBuilder.Insert(7, "-");
            myStringBuilder = myStringBuilder.Insert(10, " ");
            myStringBuilder = myStringBuilder.Insert(13, ":");
            myStringBuilder = myStringBuilder.Insert(16, ":");
            myStringBuilder = myStringBuilder.Insert(19, ".");
            DateTime dt = Convert.ToDateTime(myStringBuilder.ToString());

Kindly advise if there is anyother more efficient way.

Thanks,

Can use DateTime.ParseExact method.

var date = DateTime.ParseExact("20180215031630123", "yyyyMMddhhmmssfff", CultureInfo.CurrentCulture.DateTimeFormat);
