SortKey.Equals メソッド
指定したオブジェクトが現在の SortKey と同じインスタンスかどうかを確認します。
Overrides Public Function Equals( _
ByVal value As Object _) As Boolean
[C#]
public override bool Equals(objectvalue);
[C++]
public: bool Equals(Object* value);
[JScript]
public override function Equals(
value : Object) : Boolean;
パラメータ
- value
現在の SortKey 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現在の SortKey と同じインスタンスの場合は、 true 。それ以外の場合は false 。
解説
このメソッドは、 Object.Equals をオーバーライドします。
2 つの SortKey インスタンスが、同じ文字列と同じ CompareOptions を使用して、互いに等しいと見なされる CompareInfo インスタンスから作成された場合、その 2 つのインスタンスは等しいと見なされます。
使用例
[Visual Basic, C#, C++] 異なる SortKey オブジェクトと比較した場合の Equals の結果を次のコード例に示します。
