public:
 static bool operator ==(System::Drawing::CharacterRange cr1, System::Drawing::CharacterRange cr2);
public static bool operator == (System.Drawing.CharacterRange cr1, System.Drawing.CharacterRange cr2);
static member ( = ) : System.Drawing.CharacterRange * System.Drawing.CharacterRange -> bool
Public Shared Operator == (cr1 As CharacterRange, cr2 As CharacterRange) As Boolean

Parameter

cr1
CharacterRange

Ein CharacterRange für die Gleichheitsüberprüfung.A CharacterRange to compare for equality.

cr2
CharacterRange

Ein CharacterRange für die Gleichheitsüberprüfung.A CharacterRange to compare for equality.

Gibt zurück

Boolean

true, um anzugeben, dass die beiden CharacterRange-Objekte über den gleichen First-Wert und Length-Wert verfügen, andernfalls false.true to indicate the two CharacterRange objects have the same First and Length values; otherwise, false.

Beispiele

Im folgenden Beispiel wird die Verwendung des- Equality Operators veranschaulicht.The following example demonstrates how to use the Equality operator. Fügen Sie es in ein Windows Form ein, um dieses Beispiel auszuführen.To run this example, paste it into a Windows Form. Behandeln Sie das- Paint Ereignis des Formulars, und wenden Sie die CharacterRangeEquality1 -Methode aus der Paint Ereignis Behandlungsmethode an, indem Sie e als übergeben PaintEventArgs .Handle the form's Paint event and call the CharacterRangeEquality1 method from the Paint event-handling method, passing e as 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
