Return a null from Function which returns a DateTime

Question

 public static DateTime ResolveDate()
 {
   return null;
 }

Im required to return a null value from a function which returns a DateTime Type .. My Main Objective is to NOT to use MinValue or return a new Datetime(); [Which Returns a Default Date] and Frontend display the Date as a Empty Value (Blank) -> ""

Answer 1

public static DateTime? ResolveDate() 
{ 
    if ( someconditon = true )
    {
        return DateTime.Now
    }
    else
    {
        return null; 
    } 
}

An alternative is to use something like TryParse is working

Public static bool TryResolve (out Resolvedate)
{
    if ( someconditon = true ) 
    { 
        Resolvedate = DateTime.Now 
        return true;
    } 
    else 
    {
        return false;  
    }  
}

Answer 2

Make it nullable

   public static DateTime? ResolveDate()
        {
            return null;
        }

You can then return null as you want and check accordingly

Have a read of this Nullable Types for more information.
