C# DateTime MinValue

Description

DateTime MinValue represents the smallest possible value of DateTime. This field is read-only.

Syntax

DateTime.MinValue has the following syntax.


public static readonly DateTime MinValue

Example

Represents the smallest possible value of DateTime.


using System;/* w  ww. ja v a 2 s.c om*/
public class MainClass{
  public static void Main(String[] argv){  
    DateTime date1 = new DateTime();
    Console.Write(date1);
    if (date1.Equals(DateTime.MinValue)){
       System.Console.WriteLine("  (Equals Date.MinValue)");
    }
  }
}

The code above generates the following result.

Example 2

The following code shows how to uses the DateTime.MinValue and get the ticks value.


using System;//from  w ww .j ava 2  s.  c o  m
public class MainClass
{
    public static void Main(String[] argv)
    {

        long numberOfTicks = Int64.MaxValue;
        DateTime validDate;

        // Validate the value. 
        if (numberOfTicks >= DateTime.MinValue.Ticks &&
            numberOfTicks <= DateTime.MaxValue.Ticks)
            validDate = new DateTime(numberOfTicks);
        else if (numberOfTicks < DateTime.MinValue.Ticks)
            System.Console.WriteLine("{0:N0} is less than {1:N0} ticks.",
                              numberOfTicks,
                              DateTime.MinValue.Ticks);
        else
            System.Console.WriteLine("{0:N0} is greater than {1:N0} ticks.",
                              numberOfTicks,
                              DateTime.MaxValue.Ticks);
    }
}

The code above generates the following result.
