Question

1.00/5 (1 vote)

See more:

I have three TextBoxes:

XML

TextBox1 contains fromdate

XML

TextBox2 contains todate

Both Textboxes are having 'Date' Text Mode in 'dd/MM/yyyy' format

I want to find the number of days between these two and put value in third TextBox.
I tried 'Subtract', 'TimeStamp' but didn't work.
Please Help...
This is the Code:

C#

DateTime fromDate, toDate;
       fromDate = Convert.ToDateTime(txt_fromdate.Text);
       toDate = Convert.ToDateTime(txt_todate.Text);

       DateTime fromdate = DateTime.MinValue;
       DateTime todate = DateTime.MaxValue;</pre>
       TimeSpan noofdays = todate - fromdate;
       txt_noofdays.Text = noofdays.ToString();

"Didn't work" is not informative. It does work.

What's wrong with reading original MSDN documentation?

DateTime dt1 = Convert.ToDateTime(txt1.Text);

Please see my comment to the question. Yes, it's "subtract" and also System.TimeSpan. Use subtraction properly:

C#

System.DateTime before = //...
System.DateTime after = //...
System.TimeSpan interval = before - after; // as simple as that;
// the operator '-' is defined for the DateTime struct

The further code depends on what you mean by the meaning of "number of days". If you think about it, you may understand that these words are ambiguous. But, for example,

C#

int numberOfDays = interval.Days;
double intervalInDays = interval.TotalDays;

Please see:
DateTime Structure (System)[^],
TimeSpan Structure (System)[^].

Read on the methods named as System.DateTime.*Parse*; the link is shown above.
