UInt64.Equals Methodis used to get a value which indicates whether the current instance is equal to a specified object or 64-bit unsigned long integer or not. There are 2 methods in the overload list of this method as follows:
This method is used to return a value indicating whether the current instance is equal to a specified 64-bit unsigned long integer value or not.
Syntax: public bool Equals (ulong obj); Here, it takes a 64-bit unsigned long integer value to compare to the current instance. Return Value: This method returns true if obj has the same value as this instance otherwise, false.
Below programs illustrate the use of
UInt64.Equals(UInt64)Method:
Example 1: csharp
// C# program to demonstrate the
// UInt64.Equals(UInt64) Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
// Declaring and initializing value1
ulong value1 = 5232642;
// Declaring and initializing value2
ulong value2 = 2317648;
// using Equals(UInt64) method
bool status = value1.Equals(value2);
// checking the status
if (status)
Console.WriteLine("{0} is equal to {1}",
value1, value2);
else
Console.WriteLine("{0} is not equal to {1}",
value1, value2);
}
}
Output:
5232642 is not equal to 2317648Example 2: csharp
// C# program to demonstrate the
// UInt64.Equals(UInt64) Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
// calling get() method
get(9213128, 2131978);
get(656455, 656455);
get(10120, 10120);
get(UInt64.MaxValue, UInt64.MinValue);
}
// defining get() method
public static void get(ulong value1,
ulong value2)
{
// using Equals(UInt64) method
bool status = value1.Equals(value2);
// checking the status
if (status)
Console.WriteLine("{0} is equal to {1}",
value1, value2);
else
Console.WriteLine("{0} is not equal to {1}",
value1, value2);
}
}
Output:
9213128 is not equal to 2131978 656455 is equal to 656455 10120 is equal to 10120 18446744073709551615 is not equal to 0UInt64.Equals(Object) Method
This method is used to returns a value indicating whether the current instance is equal to a specified object or not.
Syntax: public override bool Equals (object obj); Here, it takes an object to compare with the current instance. Return Value: This method returns true if obj is an instance of UInt64 and equals the value of this instance otherwise, false.
Below programs illustrate the use of the above-discussed method:
Example 1: csharp
// C# program to demonstrate the
// UInt64.Equals(Object) Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
// Declaring and initializing value1
ulong value1 = 13421227;
// Declaring and initializing value2
object value2 = 1 / 417;
// using Equals(object) method
bool status = value1.Equals(value2);
// checking the status
if (status)
Console.WriteLine("{0} is equal to {1}",
value1, value2);
else
Console.WriteLine("{0} is not equal to {1}",
value1, value2);
}
}
Output:
13421227 is not equal to 0Example 2: csharp
// C# program to demonstrate the
// UInt64.Equals(Object) Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
// calling get() method
get(1231264, 7234455);
get(1423412, (ulong)14432314);
get(7742344, (ulong)7742344);
get(5443, 7346);
}
// defining get() method
public static void get(ulong value1,
object value2)
{
// using Equals(object) method
bool status = value1.Equals(value2);
// checking the status
if (status)
Console.WriteLine("{0} is equal to {1}",
value1, value2);
else
Console.WriteLine("{0} is not equal to {1}",
value1, value2);
}
}
Output:
1231264 is not equal to 7234455 1423412 is not equal to 14432314 7742344 is equal to 7742344 5443 is not equal to 7346Reference:
