c# - 如何以string.format显示List <DayOfWeek>的所有内容？

这是一个针对不同餐厅的小型应用程序，它们一周中的哪几天开放。在界面中，我有一周中每一天的复选框。我想在每个选定的天（选中）框中输出一个string.Format。这可能吗？
这是他选中复选框的代码：

foreach (CheckBox cb in grpDaysOpen.Controls)   // Add days of week that the restaurant is open
{
    DayOfWeek enumConvertedSuccessfully;        // Will contain good enums soon
    if (cb.Checked && Enum.TryParse<DayOfWeek>(cb.Text, out enumConvertedSuccessfully))
        favoriteDiningPlace.OpenDays.Add(enumConvertedSuccessfully);
}

这是当前的替代ToString：

return string.Format(
    "{0} is a chian of {1} with a seating capacity of {2}:\r\nSmoking is {3}. Last month's sales were {4}, while last months costs were {5}. \r\nThe restaurant is open {6}",
    this.Name,
    this.Chain,
    this.SeatingCapacity,
    this.Smoking,
    this.LastMonthSales,
    this.LastMonthCosts,
    this.OpenDays);

我不知道是否需要在其中包含其他任何代码。如果您需要澄清，请告诉我。当前上述ToString输出


  “ system.collections.generic.list` [System.DayOfWeek]”


对于this.OpenDays。

最佳答案

List<DayOfWeek> d = new List<DayOfWeek> { DayOfWeek.Monday, DayOfWeek.Saturday };
string res = string.Join(", ", d);
