Visual Basic 使用Is Operator和IsNot Operator比较两个对象引用变量。 可以使用其中任一运算符来确定两个引用变量是否引用同一对象实例。 下面的示例对此进行了演示。 VB DimxAstestClassDimyAsNewtestClass() x = yIfxIsyThen' Insert code to run if x and y point to the same instance.EndIf ...
Visual Basic 比较运算符 比较运算符是指可以使用下列运算符比较两个值。当用运算符比较两个值时,结果是一个逻辑值,不是 TRUE(成立) 就是 FALSE(不成立)的运算符号。下表显示了 VB 支持的所有比较运算符。假设变量 A=10,变量 B=20,则运算符描述说明...
