Byte.Equals 方法

定义

返回一个值,该值指示 Byte 的两个实例是否表示同一个值。

重载

Equals(Byte)

返回一个值,该值指示此实例和指定的 Byte 对象是否表示相同的值。

Equals(Object)

返回一个值,该值指示此实例是否等于指定的对象。

示例

下面的代码示例确定第一个 Byte 值是否等于第二 Byte 个值,以及第一个 Byte 值是否等于第二 Byte 个值的装箱版本。

using namespace System;

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 example displays the following output:
      byteVal1 = 127, byteVal2 = 127, objectVal3 = 127

      byteVal1 equals byteVal2?: True
      byteVal1 equals objectVal3?: True
*/
// 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

*/
let byteVal1 = 0x7fuy
let byteVal2 = 127uy
let objectVal3: obj = byteVal2

printfn $"byteVal1 = {byteVal1}, byteVal2 = {byteVal2}, objectVal3 = {objectVal3}\n"
printfn $"byteVal1 equals byteVal2?: {byteVal1.Equals byteVal2}"
printfn $"byteVal1 equals objectVal3?: {byteVal1.Equals objectVal3}"

// This code example produces the following results:
//
// byteVal1 = 127, byteVal2 = 127, objectVal3 = 127
//
// byteVal1 equals byteVal2?: True
// byteVal1 equals objectVal3?: True

Class Sample
    Public Shared Sub Main() 
        Dim byteVal1 As Byte = &H7F
        Dim byteVal2 As Byte = 127
        Dim objectVal3 As Object = byteVal2

        Console.WriteLine("byteVal1 = {0}, byteVal2 = {1}, objectVal3 = {2}" & vbCrLf, _
                          byteVal1, byteVal2, objectVal3)
        Console.WriteLine("byteVal1 equals byteVal2?: {0}", byteVal1.Equals(byteVal2))
        Console.WriteLine("byteVal1 equals objectVal3?: {0}", byteVal1.Equals(objectVal3))
    End Sub

Equals(Byte)

返回一个值,该值指示此实例和指定的 Byte 对象是否表示相同的值。

public:
 virtual bool Equals(System::Byte obj);
public bool Equals (byte obj);
override this.Equals : byte -> bool
Public Function Equals (obj As Byte) As Boolean

参数

obj
Byte

要与此实例进行比较的对象。

返回

Boolean

如果 true 与此实例相等,则为 obj;否则为 false

实现

注解

此方法实现 System.IEquatable<T> 接口,并且性能略好于 Equals(Object) 因为它不必将 obj 参数转换为对象。

适用于

Equals(Object)

返回一个值,该值指示此实例是否等于指定的对象。

public:
 override bool Equals(System::Object ^ obj);
public override bool Equals (object obj);
public override bool Equals (object? obj);
override this.Equals : obj -> bool
Public Overrides Function Equals (obj As Object) As Boolean

参数

obj
Object

与此实例进行比较的对象,或为 null

返回

Boolean

如果 trueobj 的实例并且等于此实例的值,则为 Byte;否则为 false
