DateTime.Equals Method (DateTime)

Returns a value indicating whether the value of this instance is equal to the value of the specified DateTime instance.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public bool Equals(
	DateTime value
)

Parameters

value
Type: System.DateTime

The object to compare to this instance.

Return Value

Type: System.Boolean
true if the value parameter equals the value of this instance; otherwise, false.

Implements

IEquatable<T>.Equals(T)

The current instance and value are equal if their Ticks property values are equal. Their Kind property values are not considered in the test for equality.

This method implements the System.IEquatable<T> interface, and performs slightly better than the Equals method because the value parameter does not have to be converted to an object.

The following example demonstrates the Equals method.

using System;

public class Application
{
    public static void Main()
    {
        // Create some DateTime objects.
        DateTime one = DateTime.UtcNow;

        DateTime two = DateTime.Now;

        DateTime three = one;

        // Compare the DateTime objects and display the results. 
        bool result = one.Equals(two);

        Console.WriteLine("The result of comparing DateTime object one and two is: {0}.", result);

        result = one.Equals(three);

        Console.WriteLine("The result of comparing DateTime object one and three is: {0}.", result);
    }
}

// This code example displays the following: 
// 
// The result of comparing DateTime object one and two is: False. 
// The result of comparing DateTime object one and three is: True.
