基本上，我这里有几个循环显示一周中的所有日子以及一个月中的所有日子。这都放在一张桌子里面，所以你得到

MTWTFSSMT WTFSSMM TWTFSSM

    12345678910 11 12 13 14 + + 至 31 1234567

我正在尝试编写一种方法，使我可以将一周中的所有这些天和月中的天分开，以便我的代码每个月返回该月的所有天和一周中的所有天，而不仅仅是我的所有天我的时间跨度之间的几个月，但将它们分开

可能

使用 LINQ：

DateTime startDate = new DateTime(2010, 1, 1);
DateTime endDate = new DateTime(2010, 12, 31);

int monthCount =
    (endDate.Month - startDate.Month + 1) +
    (endDate.Year - startDate.Year) * 12;

Enumerable
    .Range(0, monthCount)
    .Select(x => new DateTime(startDate.Year, startDate.Month, 1).AddMonths(x))
    .ToList()
    .ForEach(d1 =>
    {
        string month = d1.ToString("MMMM");
        // here should be your code
        // to work with months

        Enumerable
            .Range(0, d1.AddMonths(1).AddDays(-1).Day)
            .Select(x => d1.AddDays(x))
            .ToList()
            .ForEach(d2 =>
            {
                string dayOfWeek = d2.ToString("ddd");
                string day = d2.Day.ToString();
                // here should be your code
                // to work with days
            });
    });

好的，下一个不带的变体LINQ：

StringBuilder sb = new StringBuilder();

DateTime startDate = new DateTime(2010, 1, 1);
DateTime endDate = new DateTime(2012, 12, 31);

int monthCount =
    (endDate.Month - startDate.Month + 1) +
    (endDate.Year - startDate.Year) * 12;

for (int i = 0; i < monthCount; i++)
{
    DateTime d1 = new DateTime(startDate.Year, startDate.Month, 1).AddMonths(i);
    string month = d1.ToString("MMMM");

    sb.AppendFormat("<p>{0}</p>", month);

    int daysInMonth = d1.AddMonths(1).AddDays(-1).Day;
    StringBuilder daysOfWeekRow = new StringBuilder();
    StringBuilder daysRow = new StringBuilder();
    for (int j = 0; j < daysInMonth; j++)
    {
        DateTime d2 = d1.AddDays(j);
        string dayOfWeek = d2.ToString("ddd");
        string day = d2.Day.ToString();

        daysOfWeekRow.AppendFormat("<td>{0}</td>", dayOfWeek);
        daysRow.AppendFormat("<td>{0}</td>", day);
    }
    sb.AppendFormat(
        "<table><tr>{0}</tr><tr>{1}</tr></table>",
        daysOfWeekRow.ToString(), 
        daysRow.ToString()
    );
}

string result = sb.ToString();

您可以根据需要更改输出格式，我只提供了基本示例。

主要的是遍历必要的日期（使用或不使用LINQ是您的选择，但您可以同意LINQ更优雅的解决方案）并在必要的地方添加自定义格式（我将注释放在第一个例子）。

嗨，我对 linq 不熟悉，尽管我尝试了另一种方法，但我仍然遇到了一些麻烦。我认为这与我对 for 循环的编码方式有关。无论如何，使用linq可以做到这一点吗？
