DateTime.SpecifyKind() Method in C#

This method is used to create a new DateTime object which has the same number of ticks as the specified DateTime but is designated as either local time, Coordinated Universal Time (UTC), or neither, as indicated by the specified DateTimeKind value.

Syntax: public static DateTime SpecifyKind (DateTime value, DateTimeKind kind);

Parameters:
value: It is the date and time.
kind: It is one of the enumeration values which indicates whether the new object represents local time, UTC, or neither.

Return Value: This method returns a new object that has the same number of ticks as the object represented by the value parameter and the DateTimeKind value specified by the kind parameter.

Below programs illustrate the use of DateTime.SpecifyKind(DateTime, DateTimeKind) Method:

Example 1:

// C# program to demonstrate the
// DateTime.SpecifyKind(DateTime,
// DateTimeKind) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {

        // creating object of DateTime
        DateTime date = new DateTime(2005, 5,
                                6, 14, 34, 42);

        Console.WriteLine("Kind Before Using Method: "
                                          +date.Kind);

        // getting DateTime of same DateTime
        // instance using SpecifyKind() method
        DateTime value = DateTime.SpecifyKind(date,
                            DateTimeKind.Local);

        Console.WriteLine("Kind After Using Method: " +
                                            value.Kind);

        Console.WriteLine("DateTime is {0}",
                                    value);
    }
}

Output:

Kind Before Using Method: Unspecified
Kind After Using Method: Local
DateTime is 05/06/2005 14:34:42

Example 2:

// C# program to demonstrate the
// DateTime.SpecifyKind(DateTime,
// DateTimeKind) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {

        // creating object of DateTime
        DateTime date = new DateTime(1970, 1,
                                1, 4, 0, 15);

        // getting DateTime of same DateTime
        // instance using SpecifyKind() method
        DateTime value = DateTime.SpecifyKind(date,
                               DateTimeKind.Local);

        Console.WriteLine("DateTime is {0}", value);
    }
}

Output:

DateTime is 01/01/1970 04:00:15
