Question

I have two textBox in first i have Date in this format : 2012.09.20 and in the second i have Time in this format: 15:30:00. In database i have Column name “Eventstart” type: DateTime. Now i like to take the value from two textbox and put them in something like this:

DateTime end = Convert.ToDateTime(TextBoxEnd.Text) + Convert.ToDateTime(TextBoxTimeEnd.Text);

But give me this error : Error 2 Operator ‘+’ cannot be applied to operands of type ‘System.DateTime’ and ‘System.DateTime’

Answer 1

Concatenate your TextBoxes text and use DateTime.ParseExact with format "yyyy.MM.dd HH:mm:ss"

After concatenating the text you should have: "2012.09.20 15:30:00"

DateTime dt = DateTime.ParseExact(TextBoxEnd.Text + " " + TextBoxTimeEnd.Text, 
                                  "yyyy.MM.dd HH:mm:ss", 
                                  CultureInfo.InvariantCulture);
