Byte.Equals 方法

定義

命名空間:

System

組件:

System.Runtime.dll

組件:

netstandard.dll

組件:

mscorlib.dll

傳回值，該值表示 Byte 的兩個執行個體是否代表相同值。

多載

Equals(Byte)	傳回值，該值表示這個執行個體和指定的 Byte 物件是否代表相同值。
Equals(Object)	傳回值，該值表示這個執行個體是否和指定的物件相等。

範例

下列程式碼範例會判斷第一個 Byte 值是否等於第二個值 Byte ，以及第一個 Byte 值是否等於第二個值的已封裝版本 Byte 。

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

Equals(Byte)

傳回值，該值表示這個執行個體和指定的 Byte 物件是否代表相同值。

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

參數

obj

Byte

與這個執行個體相比較的物件。

傳回

Boolean

如果 obj 等於這個執行個體則為 true，否則為 false。

實作

Equals(T)

備註

這個方法會實作為 System.IEquatable<T> 介面，而且執行方式稍微優於， Equals(Object) 因為它不需要將 obj 參數轉換成物件。

• Equals(Object)

Equals(Object)

傳回值，該值表示這個執行個體是否和指定的物件相等。

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

參數

obj

Object

與這個執行個體相比較的物件，或 null。

傳回

Boolean

如果 obj 是 Byte 的執行個體，並且等於這個執行個體的值，則為 true，否則為 false。
