将日期从波斯语转换为公历

Question

如何使用 System.globalization.PersianCalendar 将波斯日期转换为公历日期？ 请注意，我想转换我的波斯日期（例如今天是 1391/04/07）并获得公历日期结果，在本例中为 06/27/2012。 我正在数秒等待答案......

Answer 1

其实很简单：

// I'm assuming that 1391 is the year, 4 is the month and 7 is the day
DateTime dt = new DateTime(1391, 4, 7, persianCalendar);
// Now use DateTime, which is always in the Gregorian calendar

当您调用

DateTime

构造函数并传入

Calendar

时，它会为您进行转换 - 因此在本例中

dt.Year

将是 2012 年。如果你想走另一条路，你需要构造适当的

DateTime

然后使用

Calendar.GetYear(DateTime)

等

简短但完整的程序：

using System;
using System.Globalization;

class Test
{
    static void Main()
    {
        PersianCalendar pc = new PersianCalendar();
        DateTime dt = new DateTime(1391, 4, 7, pc);
        Console.WriteLine(dt.ToString(CultureInfo.InvariantCulture));
    }
}

打印 06/27/2012 00:00:00。

Answer 2

您可以使用此代码将波斯日期转换为公历。

// Persian Date
var value = "1396/11/27";
// Convert to Miladi
DateTime dt = DateTime.Parse(value, new CultureInfo("fa-IR"));
// Get Utc Date
var dt_utc = dt.ToUniversalTime();

Answer 3

您可以使用此代码

return new DateTime(dt.Year,dt.Month,dt.Day,new System.Globalization.PersianCalendar());

Answer 4

我有一个扩展方法：

 public static DateTime PersianDateStringToDateTime(this string persianDate)
 {
        PersianCalendar pc = new PersianCalendar();

        var persianDateSplitedParts = persianDate.Split('/');
        DateTime dateTime = new DateTime(int.Parse(persianDateSplitedParts[0]), int.Parse(persianDateSplitedParts[1]), int.Parse(persianDateSplitedParts[2]), pc);
        return DateTime.Parse(dateTime.ToString(CultureInfo.CreateSpecificCulture("en-US")));
 }

了解更多格式和文化特定格式

示例：将

1391/04/07

转换为

06/27/2012

Answer 5

我在 Windows 7 和 10 上测试了这段代码，运行良好，没有任何问题

    /// <summary>
    /// Converts a Shamsi Date To Milady Date
    /// </summary>
    /// <param name="shamsiDate">string value in format "yyyy/mm/dd" or "yyyy-mm-dd"                     
     ///as shamsi date </param>
    /// <returns>return a DateTime in standard date format </returns>
public static DateTime? ShamsiToMilady(string shamsiDate)
    {
        if (string.IsNullOrEmpty(shamsiDate))
            return null;

        string[] datepart = shamsiDate.Split(new char[] { '/', '-' });
        if (datepart.Length != 3)
            return null;
        // 139p/k/b validation
        int year = 0, month = 0, day = 0;
        DateTime miladyDate;
        try
        {
            year = datepart[0].Length == 4 ? int.Parse(datepart[0]) : 
                                    int.Parse(datepart[2]);
            month = int.Parse(datepart[1]);
            day = datepart[0].Length == 4 ? int.Parse(datepart[2]) : 
                               int.Parse(datepart[0]);
            var currentCulture = Thread.CurrentThread.CurrentCulture;
            Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;
            miladyDate = new DateTime(year, month, day, new PersianCalendar());
            Thread.CurrentThread.CurrentCulture = currentCulture;
        }
        catch
        {
            return null;
        }

        return miladyDate;
    }

Answer 6

安装 Nuget 包：Persian_Extention 并像这样使用：

DateTime StartDate= StartDateStr.ToGregorianDateTime();
Or
String StartDateStr = StartDate.ToShamsiDate();

Answer 7

由于未知的原因，没有任何解决方案对我有用。所以我找到了一个有效的解决方案。

Public Function ShamsiToMiladi(GDay As Long, GMonth As Long, GYear As Long) As Date
    Dim PDay As Integer = New Date(GYear, GMonth, GDay, New System.Globalization.PersianCalendar).Day
    Dim PMonth As Integer = New Date(GYear, GMonth, GDay, New System.Globalization.PersianCalendar).Month
    Dim PYear As Integer = New Date(GYear, GMonth, GDay, New System.Globalization.PersianCalendar).Year
    Return DateSerial(PYear, PMonth, PDay)
End Function

Answer 8

要将公历日期转换为波斯（伊朗）日期：

string GetPersianDateYear(string PersianDate)
{
   return PersianDate.Substring(0, 4);
}

string GetPersianDateMonth(string PersianDate)
{
    if (PersianDate.Trim().Length > 8 || PersianDate.IndexOf('/') > 0 || PersianDate.IndexOf('-') > 0)
    {
        return PersianDate.Substring(5, 2);
    }
    else
    {
        return PersianDate.Substring(4, 2);
    }
}

string GetPersianDateDay(string PersianDate)
{
     if (PersianDate.Trim().Length > 8 || PersianDate.IndexOf('/') > 0 || PersianDate.IndexOf('-') > 0)
     {
         return PersianDate.Substring(8, 2);
     }
     else
     {
         return PersianDate.Substring(6, 2);
     }
 }

 var PersianDate = "1348/10/01";
 var perDate = new System.Globalization.PersianCalendar();
 var dt = perDate.ToDateTime(GetPersianDateYear(PersianDate))
                                        , int.Parse(GetPersianDateMonth(PersianDate))
                                        , int.Parse(GetPersianDateDay(PersianDate)), 0, 0, 0, 0);

Answer 9

返回persianCalendar.GetYear(日期).ToString("0000")+"/"+persianCalendar.GetMonth(日期).ToString("00")+"/"+persianCalendar.GetDayOfMonth(日期).ToString("00" );
