UWP C# Date.Time.Now + x [days]

Question

Hello,

I want to use date +[x days] like ex.: DateTime.Now.Day +7days; But when it reaches next month I want to add next month to DateTime.Now.Month; + DateTime.Now.LeftDay's;
Is it possible to use somehow a code to calculate date automaticlly, because using if's is a waste of time and space? - I would have to spend a lot of time building code with if's for every case.

Detail Description:
I want to show first 14 days for a room if it is available or not. So when I start with DateTime.Now.Day, and the next day DateTime.Now.Day +1; but if it is end of a month I want to DateTime.Now.Month +1 and then DateTime.Now.Day =1; and so on...

Is there a ready made code for this?

Please help, thank you.

I don't see exactly what you mean, because if I call AddDays, it increments the month if needed
For example :

DateTime dtNow = DateTime.Now;  
DateTime dtNext = dtNow.AddDays(30);                 
string sString = string.Format("Today : {0:yyyy/MM/dd}\r\nToday + 30 days : {1:yyyy/MM/dd}", dtNow, dtNext);                 
ContentDialog msgBox = new ContentDialog()  
{  
    Title = "Information",  
    Content = sString,  
    SecondaryButtonText = "OK"  
};  
await msgBox.ShowAsync();  

And I get :
