.Net没有尼泊尔日历的实现，正如您在System.Globalization的文档中看到的那样。

但是有一个nuget包似乎运作良好。 https://www.nuget.org/packages/NepaliDateConverter/

可以在github页面上找到实现细节 https://github.com/janaks09/NepaliDateConverter

安装此软件包后，您可以将英语翻译成尼泊尔语，反之亦然。

github页面的示例：

var convertedRawNepaliDate = new DateConverter().EngToNep(1993, 9, 30);

//English To Nepali date
//Separete properties for Year Month and Day.
var convertedNepaliDate = DateTime.Parse(convertedRawNepaliDate.ConvertedDate.Year.ToString() + "-" + convertedRawNepaliDate.ConvertedDate.Month.ToString() + "-" + convertedRawNepaliDate.ConvertedDate.Day.ToString());

var eqNepaliDay = convertedRawNepaliDate.ConvertedDayOfWeek; //Gives Nepali Day

//Nepali to english
var convertedRawEnglishDate = new DateConverter().NepToEng(2050, 06, 14);

var convertedNepaliDate = DateTime.Parse(convertedRawEnglishDate.ConvertedDate.Year.ToString() + "-" + convertedRawEnglishDate.ConvertedDate.Month.ToString() + "-" + convertedRawEnglishDate.ConvertedDate.Day.ToString());

var eqEnglishDay = convertedRawEnglishDate.ConvertedDayOfWeek; //Gives English Day

如何从excel文件中读取c＃中的未来日期？
