Question

我需要阅读Config文件以获取加载设置。

我的代码：

        Dim preferences As FileInfo
        preferences = New FileInfo(".\settings.conf")

        If preferences.Exists Then
            Dim objReader As New System.IO.StreamReader(".\settings.conf")
            Dim tmpLine_theme As String

            Do While objReader.Peek() <> -1
                tmpLine_theme = objReader.ReadLine()
                If tmpLine_theme.StartsWith("theme_selected: ") Then
                    tmpLine_theme = tmpLine_theme.Replace("theme_selected: ", "")
                    theme_box.Text = tmpLine_theme
                    MsgBox("Theme:" + tmpLine_theme)
                    theme_selected_var = tmpLine_theme
                Else
                    MsgBox("Not working")
                End If
            Loop

此代码会导致循环，无法继续循环。我需要获取特定的单词，然后删除并检索所需的数据。

如果我弄错了你，你试图得到包含特定单词的行？它并不难，只需几行代码：）

 Dim readFile as New List(of String)(File.ReadAllLine("path of file"))
 For each line in readFile
   If line.Contains("theme_selected: ") Then
    line.Replace("theme_selected: ","")
    MsgBox(line)
   End if
 Next

读取行在哪里是txt文件中的特定单词
