Find 1 year ago from current DateTime

Question

I want to perform this date check:

The date entered by the user should not be less than 12 months ago from the current date, e.g.

if date_value > '03-apr-2009'

How do I write .NET code to do this?

Answer 1

DateTime.Now.AddYears(-1)

Answer 2

do you mean something like:

if(date_value > DateTime.Now.AddYears(-1))
{
    //enter code here
}

Answer 3

date_value which i'm entering is in string format

[ as i did casting already as *( (System.DateTime)date_value).ToString("dd-MMM-yyyy")* ]

so now i want to make a comparision with this string (date_value) and DateTime.Now.AddYears(-1))

so can two strings be compared as such ???? (if one date value is > than the other)

OR Should i do any casting for the comparision ?
