Taking a variable from a file

[SeMcDun]

Can anyone help me?

I'm making a text-based game and wish to save all the details onto a file named PlayerInfo.ini

That's not the problem yet, just now I am concentrating on taking a variable from a file.

Hope you can help, thanks.

So you just want to read a string from a file right?

    Private Function ReadStringFromFile(ByVal inputfilename As String) As String
        Dim r As New System.IO.StreamReader(inputfilename)
        Dim MyVar As String = String.Empty
        If r.Peek <> -1 Then MyVar = CStr(r.ReadLine)
        r.Close()
        Return MyVar
    End Function

Use the same approach for other types such as booleans, integers etc.

Thanks, so does this work for more than one line in a file?

example

PlayerName = SeMcDun
PlayerLv = 1

I could take just "SeMcDun" or just "1" right?

also.. if you could be bothered, would you be able to write what each line does, for future references so i can learn why I am doing this.

If you have one string per line then you could do this;

    Dim MyValues As String() = ReadStringsFromFile("YourFileName")
    'First string is MyValues(0) 
    'Last  string is MyValues(MyValues.GetUpperBound(0))

    Private Function ReadStringsFromFile(ByVal inputfilename As String) As String()
        'Read all lines as an array of strings
        Dim strings As String() = IO.File.ReadAllLines(inputfilename)
        'Trim any leading/trailing spaces off of each string in the array
        For i As Integer = 0 To strings.GetUpperBound(0)
            strings(i) = strings(i).Trim
        Next
        Return strings
    End Function

Thanks again! I'm beginning to understand why I put stuff where. Pretty self-explanatory huh?

Well yeh, thanks and you can count on me rating your post!
