錯誤 - 將日期轉換爲顯示

Question

我需要將日期轉換爲shamsi日期

我創建了一個將DateTime轉換爲shamsi日期的方法。

當我路過一個日期的方法我得到這個錯誤

的最佳重載方法匹配「BentaAccounting.Classes.GenralClasses.FarsiDate.MiladiToShamsi（System.DateTime的）」有一些無效參數

這是我使用

方法

public static string MiladiToShamsi(DateTime Date) 
     { 
      string Result; 
      PersianCalendar FarsiDate = new PersianCalendar(); 
      Result = FarsiDate.GetYear(Date).ToString() + "/" + 
       (FarsiDate.GetMonth(Date) < 10 ? "0" + FarsiDate.GetMonth(Date).ToString() : FarsiDate.GetMonth(Date).ToString()) + "/" + 
       (FarsiDate.GetDayOfMonth(Date) < 10 ? "0" + FarsiDate.GetDayOfMonth(Date).ToString() : FarsiDate.GetDayOfMonth(Date).ToString()); 
      return Result; 
     } 

代碼並查看

<%: Html.Encode(GenralClasses.FarsiDate.MiladiToShamsi(item.OrderDate))%> 

Answer 1

嘗試這個

public static string MiladiToShamsi(DateTime Date) 
     { 
      string Result; 
      string Year; 
      string Month; 
      string Day; 
      # string Result, Year, Month, Day I don't know this works or not in asp.net 
      PersianCalendar FarsiDate = new PersianCalendar(); 
      Year = FarsiDate.GetYear(Date).ToString(); 
      Month = (FarsiDate.GetMonth(Date) < 10 ? "0" + FarsiDate.GetMonth(Date).ToString() : FarsiDate.GetMonth(Date).ToString()); 
      Day = (FarsiDate.GetDayOfMonth(Date) < 10 ? "0" + FarsiDate.GetDayOfMonth(Date).ToString() : FarsiDate.GetDayOfMonth(Date).ToString()); 
      Result = Year + "/" + Month + "/" + Day ; 
      return Result; 
     } 

Answer 2

你得到這個異常的唯一原因 - item.OrderDate的類型不是日期時間。馬比它是 字符串或其他東西。
