SelectList using DateTimeFormatInfo CurrentInfo GetMonthName?

I trying to build a SelectList using the System.Globalization.DateTimeFormatInfo.CurrentInfo.GetMonthName enumeration. The code works without error, just not loading the DropDownListFor correctly. As you might expect it looks like this:

       { I = 1, M = January }
      { I = 2, M = February }
        etc...

I thought it would be nice to build it as a single-line-of-code like I did for a YearSelectList like so:

       YearsSelectList = new SelectList(Enumerable.Range(DateTime.Today.Year, 15))  

Here's my current code...

[Action]
MonthsSelectList = new SelectList(Enumerable.Range(1, 12).Select(i => new { I = i, M = System.Globalization.DateTimeFormatInfo.CurrentInfo.GetMonthName(i) }))

[View]
@Html.DropDownListFor(model => model.MonthId, new SelectList(Model.MonthsSelectList, "Value", "Text"), "-select-")
