vb.net搜索字符串

VB.Net如何利用"文本中是否包含某字符串"作为判断条件应该用什么函数?

例如1：Instr(1,"abcde","a"),返回1

vb.net 查找字符串

简单点写.

Module Program

Sub Main()

Console.WriteLine("Hello World!")

Dim t As String, a() As String, c As Integer

t="/admin/index/login/defasd.php"

a=t.Split("/"c)

c=0

For Each p In a

If c0 Then

Console.WriteLine("/"+p)

End If

c+=1

Next

Console.Write("Press any key to continue . . . ")

Console.ReadKey(True)

End Sub

End Module

========

Hello World!

/admin

/index

/login

/defasd.php

vb.net 中的字符串搜索、查找功能在哪里

有啊,用正则表达式,下面是简单的例子

Imports?System.Text.RegularExpressions

Public?Class?Form1

Private?Sub?Button1_Click(ByVal?sender?As?System.Object,?ByVal?e?As?System.EventArgs)?Handles?Button1.Click

?Dim?str?As?String?=?"ABCDAEAFAG"

?Dim?Patter?As?String?=?"A"

?Dim?Matches?As?MatchCollection?=?Regex.Matches(str,?Patter,?RegexOptions.IgnoreCase?Or?RegexOptions.ExplicitCapture)

?For?Each?ws?In?Matches

??ListBox1.Items.Add("索引位置："?ws.index)

?Next

End?Sub

End?Class
