CharacterRange.Equality(CharacterRange, CharacterRange) 運算子

定義

比較兩個 CharacterRange 物件。 取得值,指出兩個 First 物件的 LengthCharacterRange 值是否相等。

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

參數

cr1
CharacterRange

比較是否相等的 CharacterRange

cr2
CharacterRange

比較是否相等的 CharacterRange

傳回

true 表示兩個 CharacterRange 物件具有相同的 FirstLength 值,否則為 false

範例

下列範例示範如何使用 Equality 運算子。 若要執行此範例,請將它貼到 Windows Form 中。 處理表單的事件 Paint ,並從事件處理方法呼叫 CharacterRangeEquality1 方法 Paint ,並 e 傳遞為 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

備註

您也可以使用 Equals 方法來測試是否相等。

這個運算子的對等方法為 CharacterRange.Equals(Object)
