Date

I want to compare between two dates. One date is System Date mm/dd/yyyy format Other one is User i/p Date in SAME FORMAT. I want to check whether the User I/P date is greater/less/euqal than the system date. How can I compare between them

I don't know what you mean by:

Anyway, you can compare dates as following myDate1 > myDate2 or myDate1 <= myDate2, etc

I want to say.. I have a table that contains columns with date value(System date). In a form a Text box (User i/p)that takes only date in a mm/dd/yyyy format if user date will be greater/less/equal than the system date,then certain event will occur. I want the C# code syntax that will compare those date. i think this give u clear view what my question is??

The date comparison examples I gave before would be how you compare dates. I'm guessing what you mean is that you want to make sure that the user enters a valid date and compare that to another date. To do this you can implement code similar to this: DateTime systemDate = DateTime.Today; DateTime userInputDate; // Try to determine if the user entered a valid date. // If it is, userInputDate will have the date value bool bValidDate = DateTime.TryParse(textBox.Text, out userInputDate); if (!bValidDate) {   // Invalid date entered, alert user  MessageBox.Show(textBox.Text + " is not a valid date!"); } else {   //Perform date comparison   if (systemDate < userInputDate)   {   } }

Convert userIPDate to DateTime

DateTime DateNow = DateTime.Now.Date;
return DateNow.CompareTo(userIPDate);

will return -1 if DateNow is less than, 1 if greater than and 0 if equal to.

The best way I have found is to subtract one DateTime from another, creating a TimeSpan object. Then use the result of the TimeSpan object to do your testing. Hope this helps! DateTime dt1 = DateTime.Now; DateTime dt2 = DateTime.Now.AddDays(1); //Compare TimeSpan ts = dt1 - dt2; if (ts.TotalMinutes < 50) { //do good stuff here } Hogan

Use a DateTimePicker, not a TextBox.
