如何使用linq c＃基于工作日（周六，周日）拆分Fromdate和Todate＃

Question

我有Fromdate和Todate。我需要根据工作日（星期六，星期日）将Fromdate和Todate分成列表

Fromdate-11/03/2016
Todate-31/03/2016

型号：

public class Splitdate
{
    public DateTime Fromdate { get; set; }
    public DateTime Todate { get; set; }
}

我需要输出一个列表：

list[0]=Fromdate:11/03/2016 Todate:11/03/2016
list[1]=Fromdate:14/03/2016 Todate:18/03/2016
list[2]=Fromdate:21/03/2016 Todate:25/03/2016
list[3]=Fromdate:28/03/2016 Todate:31/03/2016

这应该有效：

DateTime tempStart = StartDate;
var list = new List<Splitdate>();
for (DateTime date = StartDate; date.Date <= EndDate.Date; date = date.AddDays(1))
{
    if (day.DayOfWeek == DayOfWeek.Saturday)
    {
        var temp = new Splitdate();
        temp.Fromdate = tempStart;
        temp.Todate = date.AddDays(-1);
        list.Add(temp);
        tempStart.AddDays(2);
    }
}
if (tempStart <= EndDate)
{
    var temp = new Splitdate();
    temp.Fromdate = tempStart;
    temp.Todate = EndDate;
    list.Add(temp);
}

DateTime具有内置的DayOfWeek属性。循环从Fromdate到Todate的日子，并添加到基于DayOfWeek值的列表。
