Question

我正在寻找在我的网络应用程序中使用“dir”命令运行命令提示符并阅读响应...我已经工作但我需要先做另一个命令，即我需要使用CD到达正确的目录。

我可以通过基本上使用此链接获得DIR响应并将其写入屏幕：

或者这里是代码：

        If Not IsPostBack Then


        Dim _info As New ProcessStartInfo("cmd", "/C " & "DIR")

        ' The following commands are needed to redirect the
        ' standard output.  This means that it will be redirected
        ' to the Process.StandardOutput StreamReader.
        _info.RedirectStandardOutput = True

        ' Set UseShellExecute to false.  This tells the process to run
        ' as a child of the invoking program, instead of on its own.
        ' This allows us to intercept and redirect the standard output.
        _info.UseShellExecute = False

        ' Set CreateNoWindow to true, to supress the creation of
        ' a new window
        _info.CreateNoWindow = True

        ' Create a process, assign its ProcessStartInfo and start it
        Dim _p As New Process()
        _p.StartInfo = _info
        _p.Start()

        ' Capture the results in a string
        Dim _processResults As String = _p.StandardOutput.ReadToEnd()

        ' Close the process to release system resources
        _p.Close()

        ' Return the output stream to the caller
        Response.Write(_processResults)


    End If

问题出在错误的目录中......我怎么能先做一张CD otherdir ？

有人知道吗？

谢谢，

您可以尝试使用此命令连接字符

    Dim _info As New ProcessStartInfo("cmd", "/C C: & CD C:\TEMP & DIR")

Answer 2

为什么这么复杂？你可以使用这个单行：

string[] filePaths = Directory.GetFiles(@"c:\MyDir\", "*.bmp");

获取给定目录中所有文件的数组（在本例中为所有.bmp文件）。扩展参数是可选的。

通过asp.net应用程序，使用多个命令行来激活cmd提示符
