如何使用 ASP.NET 从文本框中将日期保存到 SQL SERVER

Question

I want to save the date of LeaveFrom and LeaveTo. I have tried this coding below. But it says that String was not recognized as a valid DateTime.

string leavefrom = datepicker1.Text;
DateTime lFrom = Convert.ToDateTime(leavefrom); //error occurs here

string leaveto = datepicker2.Text;
DateTime lTo = Convert.ToDateTime(leaveto);

Answer 1

From what I can see, the line that throws that error is between LINE 1 and LINE 3 wherein the conversion takes place.

Instead of using Convert.ToDateTime() function to convert the date, use DateTime.ParseExact() wherein it allows you specify the format set within the datepicker control.

Assuming the format set in datepicker is dd MMM yyyy (eg. 15 Feb 2018 ). You can simply specify it in the function's parameter:

string leavefrom = datepicker1.Text;
DateTime lFrom = DateTime.ParseExact(leavefrom, "dd MMM yyyy", CultureInfo.InvariantCulture);

Answer 2

As @john mentioned use DateTime.ParseExtract() since you have not mentioned the format of date in String i can't not point you towards exact format but using ParseExtract you can specify format like

DateTime.ParseExact(leavefrom, "dd/MM/yyyy", CultureInfo.InvariantCulture);

Hope this helps.
