BitVector32.Equals メソッド

[アーティクル]
03/28/2008

指定したオブジェクトが BitVector32 と等しいかどうかを判断します。

Overrides Public Function Equals( _
   ByVal o As Object _) As Boolean
[C#]
public override bool Equals(objecto);
[C++]
public: bool Equals(Object* o);
[JScript]
public override function Equals(
   o : Object) : Boolean;

パラメータ

o
現在の BitVector32 と比較するオブジェクト。

戻り値

指定したオブジェクトが BitVector32 に等しい場合は true 。それ以外の場合は false 。

解説

o の型が BitVector32 の型と互換性がある場合、および o の値が Data の値に等しい場合、オブジェクト o は BitVector32 に等しいと見なされます。
