Contoh

Contoh berikut menunjukkan cara menggunakan Equality operator. Untuk menjalankan contoh ini, tempelkan ke dalam Formulir Windows. Tangani peristiwa formulir Paint dan panggil CharacterRangeEquality1 metode dari Paint metode penanganan peristiwa, meneruskan e sebagai 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
