UInt16.Equals 方法
定义
重载
| 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. |
| Equals(UInt16) |
返回一个值,该值指示此实例是否等于指定的 UInt16 值。Returns a value indicating whether this instance is equal to a specified UInt16 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.
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
要与此实例进行比较的对象。An object to compare to this instance.
返回
如果 true 是 obj 的实例并且等于此实例的值,则为 UInt16;否则为 false。true if obj is an instance of UInt16 and equals the value of this instance; otherwise, false.
示例
下面的示例演示 Equals 方法。The following example demonstrates the Equals method.
UInt16 myVariable1 = 10;
UInt16 myVariable2 = 10;
//Display the declaring type.
Console::WriteLine( "\nType of 'myVariable1' is '{0}' and value is : {1}", myVariable1.GetType(), myVariable1 );
Console::WriteLine( "Type of 'myVariable2' is '{0}' and value is : {1}", myVariable2.GetType(), myVariable2 );
// Compare 'myVariable1' instance with 'myVariable2' Object.
if ( myVariable1.Equals( myVariable2 ) )
Console::WriteLine( "\nStructures 'myVariable1' and 'myVariable2' are equal" );
else
Console::WriteLine( "\nStructures 'myVariable1' and 'myVariable2' are not equal" );
UInt16 myVariable1 = 10;
UInt16 myVariable2 = 10;
//Display the declaring type.
Console.WriteLine("\nType of 'myVariable1' is '{0}' and"+
" value is :{1}",myVariable1.GetType(), myVariable1);
Console.WriteLine("Type of 'myVariable2' is '{0}' and"+
" value is :{1}",myVariable2.GetType(), myVariable2);
// Compare 'myVariable1' instance with 'myVariable2' Object.
if( myVariable1.Equals( myVariable2 ) )
Console.WriteLine( "\nStructures 'myVariable1' and "+
"'myVariable2' are equal");
else
Console.WriteLine( "\nStructures 'myVariable1' and "+
"'myVariable2' are not equal");
Dim myVariable1 As UInt16 = UInt16.Parse(10)
Dim myVariable2 As UInt16 = UInt16.Parse(10)
' Display the declaring type.
Console.WriteLine(ControlChars.NewLine + "Type of 'myVariable1' is '{0}' and" + _
" value is :{1}", myVariable1.GetType().ToString(), myVariable1.ToString())
Console.WriteLine("Type of 'myVariable2' is '{0}' and" + _
" value is :{1}" , myVariable2.GetType().ToString(), myVariable2.ToString())
' Compare 'myVariable1' instance with 'myVariable2' Object.
If myVariable1.Equals(myVariable2) Then
Console.WriteLine(ControlChars.NewLine + "Structures 'myVariable1' and" + _
" 'myVariable2' are equal")
Else
Console.WriteLine(ControlChars.NewLine + "Structures 'myVariable1' and" + _
" 'myVariable2' are not equal")
End If
调用方说明
编译器重载决策可能会考虑两种方法重载行为中的明显差异 Equals(UInt16) 。Compiler overload resolution may account for an apparent difference in the behavior of the two Equals(UInt16) method overloads. 如果定义了参数和 a 之间的隐式转换, obj UInt16 并且参数未键入为,则 Object 编译器会执行隐式转换并调用 Equals(UInt16) 方法。If an implicit conversion between the obj argument and a UInt16 is defined and the argument is not typed as an Object, compilers perform an implicit conversion and call the Equals(UInt16) method. 否则,它们调用 Equals(Object) 方法, false 如果其 obj 参数不是值,则总是返回 UInt16 。Otherwise, they call the Equals(Object) method, which always returns false if its obj argument is not a UInt16 value. 下面的示例演示两个方法重载之间的行为差异。The following example illustrates the difference in behavior between the two method overloads. 对于 Byte 值,第一次比较返回,这是 true 因为编译器会自动执行扩大转换并调用 Equals(UInt16) 方法,而第二次比较返回,这是 false 因为编译器调用了 Equals(Object) 方法。In the case of a Byte value, the first comparison returns true because the compiler automatically performs a widening conversion and calls the Equals(UInt16) method, whereas the second comparison returns false because the compiler calls the Equals(Object) method.

适用于
Equals(UInt16)
public:
virtual bool Equals(System::UInt16 obj);
public bool Equals (ushort obj);
override this.Equals : uint16 -> bool
Public Function Equals (obj As UShort) As Boolean
参数
- obj
- UInt16
要与此实例进行比较的 16 位无符号整数。A 16-bit unsigned integer to compare to this instance.
返回
如果 true 的值与此实例相同,则为 obj;否则为 false。true if obj has the same value as 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 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 because it does not have to convert the obj parameter to an object.
