将文本行加载到变量

Question

有这个文本文件，一个 .proporties 文件，我想在 VB.NET 中打开它，如果可能的话，在各个变量中使用单独的行。

这是来自 minecraft 服务器的文件，如下所示：

#Minecraft server properties
#Sun Nov 08 18:01:24 CET 2015
spawn-protection=16
max-tick-time=60000
generator-settings=
force-gamemode=false
allow-nether=true
gamemode=0
broadcast-console-to-ops=true
enable-query=false
player-idle-timeout=0
difficulty=1
spawn-monsters=true
op-permission-level=4
resource-pack-hash=
announce-player-achievements=true
pvp=true
snooper-enabled=true
level-type=DEFAULT
hardcore=false
enable-command-block=false
max-players=20
network-compression-threshold=256
max-world-size=29999984
server-port=25565
server-ip=
spawn-npcs=true
allow-flight=false
level-name=world
view-distance=10
resource-pack=
spawn-animals=true
white-list=false
generate-structures=true
online-mode=true
max-build-height=256
level-seed=
motd=A Minecraft Server
enable-rcon=false

有没有一种方法可以将文本的每一行加载到单独的行中：

dim line1 as string = readline1
dim line2 as string = readline2
dim line3 as string = readline3

所以我可以把它写成这种形式

加载后，有没有办法拆分文本，因为我只需要值，例如：max-tick-time=60000 我只需要 60000.

这可能吗？如果可以，我该怎么做？

您可以使用 System.IO.File.ReadAllLines. You can split the keys from the values using the String.Split 函数轻松读取文件中的每一行。

我建议将所有 key/value 对放在一个 Dictionary 实例中，然后将它们分配给变量：

    'Variable that holds your list of settings.
    Dim lstSettings As New Dictionary(Of String, String)

    'Loop through each line.
    For Each strLine As String In IO.File.ReadAllLines("C:\Some\FilePath.txt")

        'Ignore empty lines and comments.
        If strLine.Length > 0 AndAlso strLine.Substring(0, 1) <> "#" Then

            'Split the Key from the Value.
            Dim lstKeyValue As List(Of String) = strLine.Split("=").ToList()

            'Some additional filtering of bad data.
            If lstKeyValue.Count = 2 Then

                'Add to the Dictionary instance.
                lstSettings.Add(lstKeyValue(0), lstKeyValue(1))

            End If

        End If

    Next

    'Now assign the values to your variables or UI.
    Dim bolForceGameMode As Boolean = CBool(lstSettings("force-gamemode"))
    Dim intViewDistance As Integer = CInt(lstSettings("view-distance"))
    'etc

    'Or directly manipulate the UI:
    'txtViewDistance.Text = lstSettings("view-distance")

希望对你有用！如果您不知道某些代码的作用，请告诉我，我会解释

Public Class Form1
    Dim properties As String() = {}
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Dim text As String = My.Computer.FileSystem.ReadAllText("") 'You put the file location here
        Dim alltext As String() = text.Split(Environment.NewLine)
        For i = 2 To alltext.Length - 1
            Array.Resize(properties, properties.Length + 1)
            properties(properties.Length - 1) = alltext(i).Split("=")(0)
            Array.Resize(properties, properties.Length + 1)
            properties(properties.Length - 1) = alltext(i).Split("=")(1)
        Next
    End Sub

    Function setting(val As String)
        For i = 0 To properties.Length - 1
            If properties(i).Contains(val) Then
                Return properties(i + 1)
            End If
        Next
        Return "No results found."
    End Function

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        MsgBox(setting(TextBox1.Text)) 'You find the setting with this setting("max-tick-time")
    End Sub
End Class

你这样调用函数：

Dim allowFlight As String = setting("allow-flight")
