你说的某一维只得是某一维的什么 数组么?还是说某一维的具体对象
'''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
