在已经存在的文本文件VB.NET中写文本

Question

我一直在开发街机游戏,并且每个好的街机游戏都有一个内置的记分牌,玩家可以看到谁得分更高.我的问题是,每次进入新的分数线时,它都会删除文本文件中的所有前一行.我一直在使用的代码如下:

    If player1 > 25 Then

        objReader.Close()
        MsgBox("O " + jogador1 + " ganhou.")
        tab1.Enabled = False

        Dim wrtScore As String = "C:\Documents and Settings\Joao\My Documents\Visual Studio 2010\Projects\flaghunter\flaghunter\deposito\scores.txt"
        Dim objWriter As New System.IO.StreamWriter(wrtScore)

        wrtScore = wrtScore.Trim()

        objWriter.WriteLine(jogador1 + " " + Str(player1))

        objWriter.Close()


    End If

感谢您的关注和任何帮助.

Answer 1

请改用File.AppendText:

    // This text is always added, making the file longer over time
    // if it is not deleted.
 Using sw As StreamWriter = File.AppendText(path)
        sw.WriteLine("This")
        sw.WriteLine("is Extra")
        sw.WriteLine("Text")
 End Using

如果文件第一次不存在,则会创建该文件,如果该文件已存在,则附加文本

Dim objWriter As New System.IO.StreamWriter(wrtScore, TRUE) 附加到文件:D
