In this article, you will learn how to check if a DateTime is Null or Not Null or Empty in C#. In this article, we used the two ways to check if the Datetime is Null or Not Null or Empty.
Here are the examples to check if a DateTime is null or not null or empty in C#.
using System;
namespace Tutorialsrack
{
class Program
{
/* How to Check if a DateTime Field is Null or not Null or Empty in C# */
static void Main(string[] args)
{
DateTime Date = new DateTime(2020, 02, 05);
DateTime? NullDate =null;
Console.WriteLine("Datetime is Null or Empty: {0}",IsDateTimeNullorEmpty(Date));
Console.WriteLine("Datetime is Null or Empty: {0}", IsDateTimeNullorEmpty(NullDate));
//Hit ENTER to exit the program
Console.ReadKey();
}
public static bool IsDateTimeNullorEmpty(DateTime? date)
{
return date == null ? true : false;
}
}
}Datetime is Null or Empty: False
Datetime is Null or Empty: True
using System;
namespace Tutorialsrack
{
class Program
{
/* How to Check if a DateTime Field is Null or not Null or Empty in C# */
static void Main(string[] args)
{
DateTime Date = new DateTime(2020, 02, 05);
DateTime? NullDate =null;
Console.WriteLine("Datetime is Null or Empty: {0}", IsDateTimeNullorEmpty1(Date));
Console.WriteLine("Datetime is Null or Empty: {0}", IsDateTimeNullorEmpty1(NullDate));
//Hit ENTER to exit the program
Console.ReadKey();
}
public static bool IsDateTimeNullorEmpty1(DateTime? date)
{
return !date.HasValue ? true : false;
}
}
}Datetime is Null or Empty: False
Datetime is Null or Empty: True
I hope this article will help you to understand how to check if a DateTime is Null or Not Null or Empty in C#.
