生成身份证验证程序 vb

以下是一个生成身份证验证程序的VB代码示例：

Module Module1
    Sub Main()
        Console.WriteLine("请输入身份证号码：")
        Dim idCard As String = Console.ReadLine()
        If ValidateIdCard(idCard) Then
            Console.WriteLine("身份证号码验证通过")
        Else
            Console.WriteLine("身份证号码验证失败")
        End If
        Console.ReadLine()
    End Sub

    Function ValidateIdCard(idCard As String) As Boolean
        ' 验证身份证号码的规则
        Dim regex As New System.Text.RegularExpressions.Regex("\d{17}[\d|x]|\d{15}")
        If Not regex.IsMatch(idCard) Then
            Return False
        End If

        ' 验证身份证号码的校验位
        Dim provinceCode As Integer = Integer.Parse(idCard.Substring(0, 2))
        If provinceCode < 11 OrElse provinceCode > 91 Then
            Return False
        End If

        Dim checkCode As String = If(idCard.Length = 18, idCard.Substring(17, 1), idCard.Substring(14, 1))
        Dim factor As Integer = 2
        Dim sum As Integer = 0
        Dim verifyCode As String = "10X98765432"
        For i As Integer = 0 To 16
            sum += Integer.Parse(idCard(i).ToString()) * factor
            factor = If(factor = 2, 1, 2)
        Next
        Dim remainder As Integer = sum Mod 11
        Dim expectedCode As String = verifyCode(remainder).ToString()
        Return checkCode.ToUpper() = expectedCode
    End Function
End Module

该程序首先要求用户输入身份证号码，然后调用ValidateIdCard函数验证身份证号码是否合法。ValidateIdCard函数首先使用正则表达式验证身份证号码格式是否正确，然后根据身份证号码的校验位进行校验，最后返回验证结果
