Answer 1

这算不算循环吗？

DateTime StartDate = DateTime.Now;
List<string> filename =
    Enumerable
        .Range(-7, 8)
        .Select(n => "Report_" + StartDate.AddDays(n).ToString("dd-MM-yyyy") + ".csv")
        .ToList();

Answer 2

试试这个：

var filename = new int[8]
    .Select((d, i) => string.Format("Report_{0:dd-MM-yyyy}.csv", DateTime.Now.AddDays(-i)))
    .Reverse()
    .ToList();
