c# - easy way to loop over months and years from a given date

I have been trying to write this loop and it just keeps getting more complicated. Basically I want to take a given date and loop through every month until I reach the current month. So if the start date is 11/1/2011 then I want to loop through

11/2011, 12/2011, 1/2012, 2/2012, etc.

Here is what I started with but this does not work. Once I hit a new year I need the inner loop to start over with 1 not startdate.Month. Is there a better way in general to loop through months and years? Thanks

        for (var y = startdate.Year; y <= DateTime.Now.Year; y++)
        {
            for (var m = startdate.Month; m <= 12; m++)
            {
                  //do something with m and y
            }
        }

Date target = new Date(2011, 4, 1);
while (target < Date.Today) {
  // do something with target.Month and target.Year
  target = target.AddMonths(1);
}
