vb.net数组查找 vbnet 数组

VB.NET 找出数组中相同的元素 , 并按相同元素排序到另外一个数组中 。先把strA排序vb.net数组查找,
ind = 2
if len(strA) = 0 then return
strB(1) = strA(1)
for each s in strA
if (strA(ind)strA(ind - 1) then
count = 0
strB(ind) = strA(ind)
else
strB(ind) = strA(ind - 1)
end if
ind = ind1
next s
vb语法忘vb.net数组查找了 。。。大概是这么个意思吧 。。。。排序N LOG Nvb.net数组查找,后面是线性vb.net数组查找的Nvb.net数组查找,所以总共是NLOGN
在asp VB.NET怎么查找一维数组中特定字符串先遍历数组vb.net数组查找:
for i = 0 to Ubound(数组)
...
next
再把中间vb.net数组查找的...替换成vb.net数组查找:
if 数组(i) = 特定vb.net数组查找的字符 then msgbox "找到鸟vb.net数组查找,当前是:数组"i
vb.net 根据给定条件判断该内容是否在数组中,并读取该条数组Imports System.IO
Imports System.Collections
Imports System.Text
Public Class Form1
Dim InfoList As New ArrayList
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Dim fs As New FileStream("c:\1.txt", FileMode.Open, FileAccess.Read, FileShare.None)
Dim fw As New StreamReader(fs, Encoding.Default)
Do Until fw.EndOfStream
InfoList.Add(fw.ReadLine)
Loop
fw.Close()
fs.Close()
End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim tmp As String, a As Integer
a = -1
tmp = TextBox1.Text
For i = 0 To InfoList.Count - 1
If InStr(InfoList.Item(i).ToString, tmp)0 Then a = i : Exit For
Next
If a = 0 Then TextBox2.Text = InfoList.Item(a)
End Sub

如何查找和在vb.net一个字符串数组数重复号码面种vb.net数组查找我觉快
Dim s As String = "sadkalkdjajjdhsdsa"
Console.WriteLine(s.Split("a").Length - 1)
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 StringDim s As String = ""For i As Integer = 0 To bytes.Lengths = Convert.ToString(bytes(i))","NextReturn “,"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
vb中,如何判定一个数是否属于一个数组中的元素呢?通过循环vb.net数组查找的方式比较这个数是否和当前vb.net数组查找的数组元素一致 。
1、定义数组
dim a(3) as integer '定义一个数组(有四个数)vb.net数组查找,默认上限为a(0)
a(0)=2 '为a(0)赋值
a(1)=3
a(2)=4
a(3)=5
2、在数组中查找4
dim i as Integer'定义一个循环变量
for i=0 to UBound(a) '循环数组a,获取里面的每个元素
if a(i)=4 then
'4在数组中
end if
next i
