此前,我通过创建<代码>Financial Year类别:

public class FinancialYear
{
    int yearNumber;
    private static readonly int firstMonthInYear = 4;

    public static FinancialYear Current
    {
        get { return new FinancialYear(DateTime.Today); }
    }

    public FinancialYear(DateTime forDate) 
    {
         if (forDate.Month < firstMonthInYear) {
             yearNumber = forDate.Year + 1;
         }
         else {
             yearNumber = forDate.Year;
         }
    }

    public override string ToString() {
        return yearNumber.ToString();
    }
}

Other points:

• Have a look at IFormatProvider to see how you can customize formatting (you could provide an overload of ToString that takes a format argument like DateTime does.
• override Equals, and implement IEquitable to provide equality.
• Implement IComparable to give comarisons.
• You could also implement your own == < > >= and <= operators for the class.

如果该财政年度是可变的(例如,一个公司财政年度可能运行7月,6月,而不是4月之后;3月征税年)。

/// <summary>
/// Extension method to get the start of the financial year
/// </summary>    
public static DateTime GetStartOfFinancialYear(this DateTime date, int startMonthOfFinancialYear)
{
    if (startMonthOfFinancialYear < 1 || startMonthOfFinancialYear > 12)
        throw new ArgumentException("Must be between 1 and 12","startMonthOfFinancialYear");

    DateTime rtn = new DateTime(date.Year,startMonthOfFinancialYear,1);
    if (date.Month < startMonthOfFinancialYear)
    {
        // Current FY starts last year - e.g. given April to March FY then 1st Feb 2013 FY starts 1st April 20*12*
        rtn = rtn.AddYears(-1);
    }

    return rtn;
}

// Example, Financial Year starts in July
DateTime startFY = DateTime.Now.GetStartOfFinancialYear(7);
DateTime endFY = startFY.AddYears(1).AddDays(-1);

To improve on Russ answer above, I would suggest:

• consolidate 2 extension methods into 1 - common addition logic
• add arguments for Short/Long and the month (some need Oct instead of April)
• add default values
• leave out the "Financial Year" because some might use "Fiscal Year"

public static string ToFYString(this DateTime dateTime, bool longFlag = false, int monthLimit = 3)
{
   var format = longFlag ? "yyyy" : "yy";
   return (dateTime.Month > monthLimit ? dateTime.AddYears(1).ToString(format) : dateTime.ToString(format));
}

1. if april is your new FY, and you want short, use .ToFYString()
2. if october is your new FY and you want short use .ToFYString(monthLimit: 9)
3. if april is your new FY, and you want long, use .ToFYString(true)
4. if october is your new FY, and you want long, use .ToFYString(true, 9)

• 跟踪代码,以获取财政年度或期间值。

public int GetFinancialYear(DateTime date)
{
    return date.Month > 6 ? date.Year + 1 : date.Year;
}

public int GetFinancialPeriod(DateTime date)
{
    return date.Month > 6 ? date.Month - 6 : date.Month + 6;
}

我不敢肯定,为什么你们需要L.Q,但获得这样的东西就够了。

DateTime today = DateTime.Today;
if(today.Month <= 3)
       make this string "Financial Year " + today.ToString("yy")); // OR yyyy for 2013
else 
       "Financial Year " + today.AddYears(1).ToString("yy"));

public class FinancialYear
{
    public YearRepresentation ResolveFinancialYear(DateTime currentDate)
    {
        YearRepresentation financialYear = new YearRepresentation();
        int year = (currentDate.Month >= 4) ? currentDate.AddYears(1).Year : currentDate.Year;
        financialYear.SetYear(year);

        return financialYear;
    }
}

public class YearRepresentation
{
    public string LongYear { get; set; }

    public string ShortYear { get; set; }

    public void SetYear(int year)
    {
        this.LongYear = "Financial Year " + year;
        this.ShortYear = "FY " + year;
    }
}

这是目前财政年度的一个例子。

        string FinYear=null;

        if (DateTime.Today.Month > 3)
        {

            FinYear = "1/4/" + DateTime.Today.Year;
        }

        else
        {
            FinYear = "1/4/" + (DateTime.Today.Year - 1);
        }

Here used Valued Tuple (Finacial year start from July so, I used 7. If you want

年限至年限

然后,格式才需要使用月度和年期财产。

public  static (DateTime, DateTime) GetCurrentFinacialYearDateRange()
    {
        if(DateTime.Now.Month >= 7)
        {
            DateTime startDate = new DateTime(DateTime.Today.Year, 7, 1); // 1st July this year
            DateTime endDate = new DateTime(DateTime.Today.Year + 1, 7, 1).AddDays(-1); // Last day in June next year
            return (startDate, endDate);
        }
        else
        {
            DateTime startDate = new DateTime(DateTime.Today.Year-1, 7, 1); // 1st July this year
            DateTime endDate = new DateTime(DateTime.Today.Year, 7, 1).AddDays(-1); // Last day in June next year
            return (startDate, endDate);
        }
        
    }
