vb.net搜索数组,c语言数组搜索

vb.net 从数组{5,7,11,13,17,19}中取一个数，取三次（可以是相同的数），三次之和有几个值？求代码！

Sub 和()

Dim Arr, Dic As Object, i, j, k

Set Dic = CreateObject("Scripting.Dictionary")

Arr = Array(5, 7, 11, 13, 17, 19)

For i = 0 To UBound(Arr)

For j = 0 To UBound(Arr)

For k = 0 To UBound(Arr)

Dic(Arr(i) + Arr(j) + Arr(k)) = ""

Next k

Next j

Next i

MsgBox Dic.Count

Set Dic = Nothing

End Sub

结果为22种不同的和值。

Q1: vb.net如何在数组中查找数组?

'''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

Q2: 在asp VB.NET怎么查找一维数组中特定字符串

先遍历数组：

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
