vb.net - vb.net 进程无法访问该文件，因为它正被另一个进程使用

Question

您好，我想打开一个 csv 文件并在其中写入文本。这是代码：

尝试

    Dim path As String = "C:\Users\daaemoon\Desktop\Test.csv"
    Dim reader As StreamReader = New System.IO.StreamReader(File.OpenRead(path))

    Dim sw As New StreamWriter(path)
    Dim s As String = String.Empty

    While reader.Peek() >= 0
        Dim line As String = reader.ReadLine()
        Dim values As String() = line.Split(";"c)
        listforfalsecsv.Add(values(0))
        s = s + line + Chr(10)
    End While
    reader.Close()
    sw.Write(s)
    sw.Close()


Catch ex As Exception
    MessageBox.Show(ex.Message)
End Try

我通过以下行得到了错误：

  Dim sw As New StreamWriter(path)

如果我在该行之后使用方法 reader.dispose() Dim reader As StreamReader = New System.IO.StreamReader(File.OpenRead(path))

我来到了while循环，但我得到了一个错误：无法读取来自关闭的文本阅读器。

我需要帮助，请帮助我。
