Parametri

Valori restituiti

true per indicare che i due CharacterRange oggetti hanno gli stessi First valori e Length ; in caso contrario, false.

Esempio

Nell'esempio seguente viene illustrato come usare l'operatore Equality . Per eseguire questo esempio, incollarlo in un Windows Form. Gestire l'evento del Paint modulo e chiamare il CharacterRangeEquality1 metodo dal Paint metodo di gestione degli eventi, passando e come PaintEventArgs.

private void CharacterRangeEquality1()
{

    // Declare the string to draw.
    string message = "Strings or strings; that is the question.";

    // Compare the ranges for equality. The should not be equal.
    CharacterRange range1 = 
        new CharacterRange(message.IndexOf("Strings"), "Strings".Length);
    CharacterRange range2 = 
        new CharacterRange(message.IndexOf("strings"), "strings".Length);

    if (range1 == range2)
        MessageBox.Show("The ranges are equal.");
    else
        MessageBox.Show("The ranges are not equal.");
}

Private Sub CharacterRangeEquality1() 
    
    ' Declare the string to draw.
    Dim message As String = "Strings or strings; that is the question."
    
    ' Compare the ranges for equality. The should not be equal.
    Dim range1 As New CharacterRange(message.IndexOf("Strings"), _
        "Strings".Length)
    Dim range2 As New CharacterRange(message.IndexOf("strings"), _
        "strings".Length)
    
    If range1 = range2 Then
        MessageBox.Show("The ranges are equal.")
    Else
        MessageBox.Show("The ranges are not equal.")
    End If
 
End Sub

Commenti

È anche possibile verificare l'uguaglianza usando il Equals metodo .

Il metodo equivalente per questo operatore è CharacterRange.Equals(Object)
