Byte.Equals 方法
定义
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。Returns a value indicating whether this instance and a specified Byte object represent the same value. |
| Equals(Object) |
返回一个值,该值指示此实例是否等于指定的对象。Returns a value indicating whether this instance is equal to a specified object. |
示例
下面的代码示例确定第一个 Byte 值是否等于第二个值 Byte ,以及第一个值是否 Byte 等于第二个值的装箱版本 Byte 。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.
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.

Console.WriteLine("byteVal1 equals objectVal3?: {0}", byteVal1.Equals(objectVal3));

Equals(Byte)
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。An object to compare to this instance.
返回
如果 true 与此实例相等,则为 obj;否则为 false。true if obj is equal to this instance; otherwise, false.
实现
注解
此方法实现 System.IEquatable<T> 接口,并且执行的效果略优于, Equals(Object) 因为无需将 obj 参数转换为对象。This method implements the System.IEquatable<T> interface, and performs slightly better than Equals(Object) because it does not have to convert the obj parameter to an object.

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。Returns a value indicating whether this instance is equal to a specified object.
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。An object to compare with this instance, or null.
返回
如果 true 是 obj 的实例并且等于此实例的值,则为 Byte;否则为 false。true if obj is an instance of Byte and equals the value of this instance; otherwise, false.
