public:
 override bool Equals(System::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 Object Object Object

要与此实例进行比较的对象。An object to compare to this instance.

返回

如果 trueobj 的实例并且等于此实例的值,则为 UInt16;否则为 falsetrue 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

编译器重载解析行为的两个明显的差异可能会考虑Equals(UInt16)方法重载。Compiler overload resolution may account for an apparent difference in the behavior of the two Equals(UInt16) method overloads. 如果之间的隐式转换obj自变量和一个UInt16定义和自变量类型不是Object,编译器执行隐式转换和调用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,调用方法Equals(Object)方法,它始终返回false如果其obj参数不是UInt16值。Otherwise, they call the Equals(Object) method, which always returns false if its obj argument is not a UInt16 value. 下面的示例说明了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. 情况下Byte值,第一次比较将返回true因为编译器会自动执行扩大转换和调用Equals(UInt16)方法,而第二个比较返回false因为编译器将调用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.

Equals(UInt16) Equals(UInt16) Equals(UInt16) 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.

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 UInt16 UInt16 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 falsetrue 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,并且执行略微优于Equals因为它不具有要转换obj参数的对象。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.
