Set MinValue in datetimepicker in c# - c#

Hi I want user to select dates which is 6 months or higher than the current date but I don't know where should I start.
Please help me fix this. Thank you!


Please check below solution
DateTimePicker dateTimePicker= new DateTimePicker();
dateTimePicker.MinDate = DateTime.Now;
dateTimePicker.MaxDate = DateTime.Now.AddMonths(6);


You can take the min DateTime value. Try like:
var minDate = DateTime.MinValue;

How to add month or year or day to the selected date in c#?

DateTime ct = DateTime.Now.Date;
ct.AddMonths(5);
I am trying to get next 5th month from the current date. This code is not working for me.

AddMonths does not affect the original object, it returns a new object (MSDN).
You need to assign the result:
DateTime ct = DateTime.Now.Date;
DateTime future = ct.AddMonths(5);

You should use
var ct = DateTime.Date.AddMonths(5)

ct = ct.AddMonths(5);
it returns that date not adds to itself

Set a variable date to six months prior to today

I am trying to set a variable that calculates the date six months prior to today's date.
string exampleDate = (DateTime.TodaysDate) - (00/06/00)
Or something like that... I know the above definitely does not work.
I would be grateful for any ideas.
Thanks

DateTime date = DateTime.Now.AddMonths(-6);
// if you want to convert to string:
string myDate = date.ToString();

Simply:
var sixMonthsPriorToNow = DateTime.Now.AddMonths(-6);

doing math with dates

I am writing a program in c# and I need to do some math with dates. I need to let the user enter a date, calculate the date that is 91 days later, and then find the month right after that. ex: user enters date of 1/15/12, it should add 91 days, 4/15/12, and then return a date of 5/1/12. Unfortunately, I have no idea how to do this and I couldn't find anything that was helpful.

var oldDate = <your_datetime_variable>.AddDays(91);
var newDate = new DateTime(oldDate.Year, oldDate.Month, 1).AddMonths(1);

Since constructing a new DateTime object has been suggested, here is another approach:
DateTime when = <user_supplied_date>;
DateTime future = when.AddDays(91);
when = future.AddDays(-(future.Day - 1)).AddMonths(1);
This is a little cryptic, but results in a one-liner that you could use.

How to change the datetimepicker value automatically while in progress

I want to know is there any way to change the datetimpePicker value while in progress.
I am using this code to go the next day .
DateTime stdate = new DateTime();
stdate = dateTimePicker1.Value;
while (stdate <= DateTime.Now)
{
txtSelectedDate.Text = stdate.ToString("yyyyMMdd");
selectedDate = Convert.ToInt32(txtSelectedDate.Text);
stdate = stdate.AddDays(1);
}
I want to change the datetimepicker value while in progress automatically because my my code works on date value if i select the date which is not present in the files it does not works , if i change the datetimepicker value which the file haves it works fine.
I want to change the datetimepicker value while in progress automatically.
There would be great appreciation if someone coulde help me.
Thanks In Advance.

I'm not sure if I've understood your question but if you're looking to update the DateTimePicker after each increment, you just need to affect its Value property, something like this:
stdate = stdate.AddDays(1);
dateTimePicker1.Value = stdate;

Adding days to a DateTime in C#

Is it possible to add dates in C#?
(DateTime.Today.ToLongDateString() + 10)
I tried this but it doesn't work.

Do you want to add days?
DateTime newDate = DateTime.Today.AddDays(10);
Note that you get a new DateTime back!
MSDN

Use DateTime.Today.AddDays(10) or any of the other AddXXX functions on DateTime.

What is the unit of 10. If it is days; then
var todayPlus10Days = DateTime.Today.AddDays(10);

Use AddDays() method:
DateTime dt = DateTime.Today;
dt = dt.AddDays(10);
