AddDays () for the loop

Question

I want to use the AddDays () method for a loop. But that will not work. despite being used in a loop, the value of the day does not increase. Then it transforms an infinite loop. For instance:

DateTime exDt = tempPermissionWarning[i].planned_start_date; for (DateTime dt = exDt; dt <= newTo; dt.AddDays(1)) { context = context + dt.ToShortDateString() + "æ" + tempPermissionWarning[i].resource_name) + ¨"; } 

How do I use the AddDays () method in a for loop

Thank you very much

Answer 1

dt.AddDays(1) returns the new object that you are dropping.

You can use dt = dt.AddDays(1) in a for loop instead of what you have.

Answer 2

AddDays methods return a new DateTime , so your dt object will never be modified. However, you can reassign it. This should work:

 for (DateTime dt = exDt; dt <= newTo; dt = dt.AddDays(1)) { ... }
