私はDatetimeから秒、分単位、時間、日、月などを返したいと思います。

私は多くの場合、私は与えられた日時について

を次の値

でコードをテストしたコード

public static string ReturnCreatedSince(DateTime createdOn) 
    { 
     //Get current datetime 
     var today = DateTime.Now; 

     // Get days in current month 
     var daysInMonth = DateTime.DaysInMonth(today.Year, today.Month); 

     double seconds = 60; 
     double minutes = seconds * 60; 
     double hours = minutes * 60; 
     double days = hours * 24; 
     //double weeks = days * 7; 
     double months = days * daysInMonth; 
     double years = months * 12; 

     //Convert created datetime to seconds 
     var datetimeInSeconds = (today - createdOn).TotalSeconds; 

     var createdSince = string.Empty; 

     if (datetimeInSeconds <= seconds) //seconds between 1 to 60 
     { 
      return TimeSpan.FromSeconds(datetimeInSeconds).Seconds.ToString() + " sec"; 
     } 
     else if (datetimeInSeconds <= minutes)// Minuites between 1 to 60 
     { 
      return TimeSpan.FromSeconds(datetimeInSeconds).Minutes.ToString() + " mins"; 
     } 
     else if (datetimeInSeconds <= hours)// Hours between 1 to 24 
     { 
      return TimeSpan.FromSeconds(datetimeInSeconds).Hours.ToString() + " hrs";     
     } 
     else if (datetimeInSeconds <= days)// Days between 1 to 24 
     { 
      return TimeSpan.FromSeconds(datetimeInSeconds).Days.ToString() + " jrs"; 
     }   
     else if (datetimeInSeconds <= months)// Months between 1 to 24 
     { 
      return (datetimeInSeconds/months).ToString() + " m"; 
     } 
     else if (datetimeInSeconds <= years)// Years between 1 to 12 
     { 
      return (datetimeInSeconds/years).ToString() + " yrs"; 
     } 
     else 
     { 
      return createdOn.ToShortDateString(); 
     } 
    } 

のこのスニペットを書きました秒が60未満の場合、値を返す必要があります秒です。 秒数が60以下で（60 * 60）秒未満の場合は、分単位で値を返します。

今この日付は"createdOn": "2017-10-16T14:41:16.557"です1か月の代わりに41日。私は埋め込まれたメソッドを使用する方が簡単かもしれませんそれを

を修正することができますどのように

：

DateTime startDate = new DateTime(1970, 01, 01); 
DateTime endDate = DateTime.Now.ToUniversalTime(); 
TimeSpan diff = (endDate - startDate); 

Console.WriteLine("Number of seconds:" + diff.TotalSeconds); 
Console.WriteLine("Number of minutes:" + diff.TotalDays); 
Console.WriteLine("Number of hours:" + diff.TotalHours); 
Console.WriteLine("Number of days:" + diff.TotalDays); 

//months 
int nbMonths = ((endDate.Year - startDate.Year) * 12) + endDate.Month - startDate.Month; 
Console.WriteLine("Number of months:" + nbMonths); 
//years 
int nbYears = endDate.Year - startDate.Year; 
Console.WriteLine("Number of years:" + nbYears); 
Console.ReadKey();
