Byte.Equals Method (Byte)

Returns a value indicating whether this instance and a specified Byte object represent the same value.

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

public bool Equals (
	byte obj
)
public final boolean Equals (
	byte obj
)
public final function Equals (
	obj : byte
) : boolean
Not applicable.

Parameters

obj

A Byte object to compare to this instance.

Return Value

true if obj is equal to this instance; otherwise, false.

This method implements the System.IEquatable interface, and performs slightly better than Equals because it does not have to convert the obj parameter to an object.

If obj has fewer bits (is narrower) than the instance type, some programming languages perform an implicit widening conversion that transforms the value of the parameter into a value with more bits.

For example, suppose the instance type is Int32 and the parameter type is Byte. The Microsoft C# compiler generates instructions to represent the value of the parameter as an Int32, then generates a Int32.CompareTo method to compare the Int32 instance and parameter representation.

Consult your programming language's documentation to determine whether its compiler performs implicit widening conversions on numeric types.

The following code example determines whether the first Byte value is equal to the second Byte value, and whether the first Byte value is equal to the boxed version of the second Byte value.

// This code example demonstrates the System.Byte.Equals(Object) and
// System.Byte.Equals(Byte) methods.

using System;

class Sample 
{
    public static void Main() 
    {
    byte   byteVal1 = 0x7f;
    byte   byteVal2 = 127;
    object objectVal3 = byteVal2;
//
    Console.WriteLine("byteVal1 = {0}, byteVal2 = {1}, objectVal3 = {2}\n",
                       byteVal1, byteVal2, objectVal3);
    Console.WriteLine("byteVal1 equals byteVal2?: {0}", byteVal1.Equals(byteVal2));
    Console.WriteLine("byteVal1 equals objectVal3?: {0}", byteVal1.Equals(objectVal3));
    }
}

/*
This code example produces the following results:

byteVal1 = 127, byteVal2 = 127, objectVal3 = 127

byteVal1 equals byteVal2?: True
byteVal1 equals objectVal3?: True
