VB.Net逻辑/位运算符

下表显示了VB.Net支持的所有逻辑运算符。假设变量A = True，变量B = False，则：

示例

尝试下面的例子来理解VB.Net中可用的所有逻辑/位运算符：
文件：logicalOp.vb -

Module logicalOp

    Sub Main()
        Dim a As Boolean = True
        Dim b As Boolean = True
        Dim c As Integer = 5
        Dim d As Integer = 20
        'logical And, Or and Xor Checking
        If (a And b) Then
            Console.WriteLine("Line 1 - Condition is true")
        End If
        If (a Or b) Then
            Console.WriteLine("Line 2 - Condition is true")
        End If
        If (a Xor b) Then
            Console.WriteLine("Line 3 - Condition is true")
        End If
        'bitwise And, Or and Xor Checking'
        If (c And d) Then
            Console.WriteLine("Line 4 - Condition is true")
        End If
        If (c Or d) Then
            Console.WriteLine("Line 5 - Condition is true")
        End If
        If (c Or d) Then
            Console.WriteLine("Line 6 - Condition is true")
        End If
        'Only logical operators
        If (a AndAlso b) Then
            Console.WriteLine("Line 7 - Condition is true")
        End If
        If (a OrElse b) Then
            Console.WriteLine("Line 8 - Condition is true")
        End If

        ' lets change the value of  a and b '
        a = False
        b = True
        If (a And b) Then
            Console.WriteLine("Line 9 - Condition is true")
        Else
            Console.WriteLine("Line 9 - Condition is not true")
        End If
        If (Not (a And b)) Then
            Console.WriteLine("Line 10 - Condition is true")
        End If
        Console.ReadLine()
    End Sub
End Module

执行上面示例代码，得到以下结果 -

F:\worksp\vb.net\operators>vbc logicalOp.vb
F:\worksp\vb.net\operators>logicalOp.exe
Line 1 - Condition is true
Line 2 - Condition is true
Line 4 - Condition is true
Line 5 - Condition is true
Line 6 - Condition is true
Line 7 - Condition is true
Line 8 - Condition is true
Line 9 - Condition is not true
Line 10 - Condition is true
