CharacterRange.Inequality(CharacterRange, CharacterRange) 运算符
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 值是否不等的值。
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 op_Inequality : System.Drawing.CharacterRange * System.Drawing.CharacterRange -> boolPublic Shared Operator != (cr1 As CharacterRange, cr2 As CharacterRange) As Boolean参数
- cr1
- CharacterRange
要比较不等性的 CharacterRange。
- cr2
- CharacterRange
要比较不等性的 CharacterRange。
返回
如果两个 CharacterRange 对象的 First 或 Length 值中的任一个不同，为 true；否则为 false。
示例
下面的示例演示如何使用 Inequality 方法。 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 CharacterRangeInequality 方法，作为 ePaintEventArgs传递。
private void CharacterRangeInequality()
{
// 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("string"), "strings".Length);
if (range1 != range2)
MessageBox.Show("The ranges are not equal.");
else
MessageBox.Show("The ranges are equal.");
}
Private Sub CharacterRangeInequality()
' 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("string"), "strings".Length)
If range1 <> range2 Then
MessageBox.Show("The ranges are not equal.")
Else
MessageBox.Show("The ranges are equal.")
End If
End Sub
注解
方法 Inequality 返回 与 方法相反的 Equality 。
此运算符的等效方法是 CharacterRange.Equals(Object)
