I want to have an if statement that goes like this:

int yrcount = 18;
SR_txtyr.Text = yrcount.ToString();

If year.now adds 1 then
yrcount adds 1

Basically, I want it to do is add 1 into my variable if the date proceeds to next year.

The textbox is disabled so it can't be altered. It's more part of a document number that changes every year.

What I have tried:

I don't know how date time works, sadly.

Using the DateTime class, you can use the year property of the date and assign it to your variable.

Solution 1

If i understand you properly...

To get current year, use this:

C#

int currentyear = DateTime.Today.Year;

or (even better):

C#

DateTime currentdate = DateTime.Today;
int currentyear = currentdate.Year;

For further details, please see: DateTime Structure (System)[^]

[EDIT]

C#

DateTime currentdate = DateTime.Today;
DateTime nextyeardate = DateTime.Today.AddMonths(8);
int currentyear = currentdate.Year;
int nextyear = nextyeardate.Year;

if (nextyear-currentyear==1)
{
	Console.WriteLine("Next year!");
}
else
{
	Console.WriteLine(":(");
}

Yes, I've covered that part already. Now, I was wondering how could I know if the year moved from 2018 to 2019. I'm at the IF part actually.

OK. Check my answer again ;)

1 question: What's the purpose of the value 8 in AddMonths?

Also, I've tried moving the computer date. When I got to 2020, It stopped adding.

Just an example, how to add 8 months to current date to get next-year date ;)
