Question

我想阅读此文件中的特定文字＆＃39; config.txt＆＃39;

action url: "item1"
referer: "item2"
post data: 'item3'

我的代码：

dim item1 as string
dim item2 as string
dim item3 as string

textbox1.text = (item1)
textbox2.text = (item2)
textbox3.text = (item3)

我希望item1 to = action url: "(*.?)" CaptureGroup(1).Value从文本文件中读取，依此类推，使用item2和item3

Answer 1

如果文件总是这种格式，也许你不需要正则表达式？： -

Dim FileContent As String = "action url: .... etc"
Dim DivArr As Char() = {Chr(34), Chr(39)}
'split into segments using single & double quotes as separators
Dim parts() As String = FileContent.Split(DivArr)

textbox1.text = parts(1)
textbox2.text = parts(3)
textbox3.text = parts(5)

Answer 2

public static int integer;

例如

Imports System.Text.RegularExpressions

 Private Function match(regex As String, html As String, Optional i As Integer = 1) As String
        Return New Regex(regex, RegexOptions.Multiline).Match(html).Groups(i).Value.Trim()
    End Function

在文本文件vb.net中使用正则表达式
