定义
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
比较两个 CharacterRange 对象。 指示两个 CharacterRange 对象的 First 和 Length 值是否相等的值。
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 -> boolPublic Shared Operator == (cr1 As CharacterRange, cr2 As CharacterRange) As Boolean参数
- cr1
- CharacterRange
一个要比较是否相等的 CharacterRange。
- cr2
- CharacterRange
一个要比较是否相等的 CharacterRange。
返回
如果两个 CharacterRange 对象的 First 和 Length 值均相同，则为 true；否则为 false。
示例
以下示例演示如何使用 Equality 运算符。 若要运行此示例，请将其粘贴到 Windows 窗体中。 处理窗体的事件Paint，并从Paint事件处理方法调用 CharacterRangeEquality1 方法，作为 ePaintEventArgs传递。
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
注解
还可以使用 Equals 方法测试相等性。
此运算符的等效方法是 CharacterRange.Equals(Object)
