C#Console在调用cmd的时候无论是cd还是F:盘符都无法更改cmd命令执行目录，有什么办法能解决呢？

C#Console在调用cmd的时候无论是cd还是F:盘符都无法更改cmd命令执行目录，有什么办法能解决呢？

一般问题倒好应付，但是遇到调用“使用log4j写log的程序”就会导致log位置错乱。请问大佬怎么解决？？？

这是代码

    public static string input(string Input)
    {
        string logs = "";
        ProcessStartInfo start = new ProcessStartInfo
        {
            FileName = "cmd.exe",
            UseShellExecute = false,
            RedirectStandardOutput = true,
            CreateNoWindow = false,
            RedirectStandardInput = true
        };
        Process Reader = Process.Start(start);
        using (Reader)
        {
            Reader.OutputDataReceived += new DataReceivedEventHandler(OutputDataReceived);
            Reader.BeginOutputReadLine();
            Reader.StandardInput.WriteLine(Input);//输入命令
            Reader.WaitForExit();
        }
        void OutputDataReceived(object sender, DataReceivedEventArgs Outputs)
        {
            if (null != Outputs)
            {
                Console.WriteLine(Outputs.Data);
                logs = logs +"\n"+ Outputs.Data;
            }
        }
        return logs;
