Subtract date from datetime

Question

I need to take current date and subtract 3 months.

Bang making conversions and subtracting 3 but will go wrong to turn the year, in January for example will result in month -2.

I believe that there is a better way of doing this.

Answer 1

Yes, there is a more suitable way. The structure DateTime has the method AddMonths, to subtract a number amount is to use this method with a negative parameter.

For example

var data = new DateTime(2017, 01, 01);
var novaData = data.AddMonths(-3);
