问题描述

我有以下数据时间:

 开始= 15/12/2012 13:00:00 
结束= 16/02/2013 14:00:00

如何将其分为3部分一个月?

   -  15-12-2012 13:00:00  - > 01-01-2013 00:00:00 
- 01-01-2013 00:00:00 - > 01-02-2013 00:00:00
- 01-02-2013 00:00:00 - > 16-02-2013 14:00:00

总次数必须保持不变。
这可以很容易地使用LINQ吗?

解决方案

确定,尝试这个(包含小帮手类) p>

进程:

  var Start = DateTime.Parse(2012年12月15日13:00:00); 
var End = DateTime.Parse(2013年2月16日14:00:00);

var runningDate =开始;
while(runningDate< End)
{
var nextMonthSeed = runningDate.AddMonths(1);
var to = DateHelper.Min(new DateTime(nextMonthSeed.Year,nextMonthSeed.Month,1),End);
Console.WriteLine({0} - > {1},runningDate.ToString(dd-MM-yyyy HH:mm:ss),to.ToString(dd-MM-yyyy HH: mm:ss));
runningDate = to;
}

助手类:

  public static class DateHelper 
{
public static DateTime Min(DateTime date1,DateTime date2)
{
return(date1< date2 ?date1:​​date2);
}
}


I have the following datetimes:

Start = 15/12/2012 13:00:00
End   = 16/02/2013 14:00:00

How can I split that in 3 parts for each month?

- 15-12-2012 13:00:00 -> 01-01-2013 00:00:00
- 01-01-2013 00:00:00 -> 01-02-2013 00:00:00
- 01-02-2013 00:00:00 -> 16-02-2013 14:00:00

The total timespan must remain the same.Can this easily be done with LINQ?

解决方案

sure, try this (with little helper class included)

Process:

var Start = DateTime.Parse("15 Dec 2012 13:00:00");
var End = DateTime.Parse("16 Feb 2013 14:00:00");

var runningDate = Start;
while (runningDate < End)
{
    var nextMonthSeed = runningDate.AddMonths(1);
    var to = DateHelper.Min(new DateTime(nextMonthSeed.Year, nextMonthSeed.Month, 1), End);
    Console.WriteLine("{0} -> {1}", runningDate.ToString("dd-MM-yyyy HH:mm:ss"), to.ToString("dd-MM-yyyy HH:mm:ss"));
    runningDate = to;
}

Helper class:

public static class DateHelper
{
    public static DateTime Min(DateTime date1, DateTime date2)
    {
        return (date1 < date2 ? date1 : date2);
    }
}
