for i = 0 to Ubound(数组)
...
next
再把中间的...替换成:
if 数组(i) = 特定的字符 then msgbox "找到鸟,当前是:数组" i
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim a() As Byte = System.IO.File.ReadAllBytes("record.db")
For Index As Integer = a.GetLowerBound(0) To a.GetUpperBound(0) - 3
If a(Index) = 56 AndAlso a(Index + 1) = 57 AndAlso a(Index + 2) = 58 AndAlso a(Index + 3) = 59 Then
Debug.Print(Index.ToString) '输出byte串位置
End If
Next
End Sub
End Class
刚学,不知道有没有直接在数组中搜索一串元素的方法。
'''这个函数功能就是用来把数组转为string的格式'''如byte()={1,2,3,4,5,6}转化后变为",1,2,3,4,5,6,"Function ByteArrayToString(bytes() As Byte) As String Dim s As String = "" For i As Integer = 0 To bytes.Length s = Convert.ToString(bytes(i)) "," Next Return “," sEnd Function Sub Search()Dim a as byte()={1,2,3,4,5,6}
Dim b as byte()={2,3,4}
Dim astr As String = ByteArrayToString(a)Dim bstr As String = ByteArrayToString(b)Dim index As Integer = astr.IndexOf(bstr) '这个index就是b数组在a数组的位置,下标从0开始,不过记得处理下逗号,因为这时候是字符串。'''如果index小于0说明没有匹配内容End Sub 现在说明下ByteArrayToString为什么要在字符串开头加个",",如果不加,可能出现a="1,23,4,5,6,", b="3,4,5,",结果导致查询位置错误,匹配了a的位置
