以目标目录路径为参数的静默安装

在我的C应用程序中,我在静默模式下运行一些设置。问题是我想让用户选择目标安装目录,但不知道如何选择。

这是静默安装,工作正常,但安装在默认目录中:

void runsilentsetup(string executablefilepath)
{

processStartInfo startInfo=新建processStartInfo()
{
createNowindow=false,
useShellExecute=真,
文件名=可执行文件路径,
windowstyle=processwindowstyle.hidden,
arguments=“/s/v/qn”
}(二)
使用(process exeprocess=process.start(startinfo))
{









void RunSilentSetup(string executableFilePath)
        {

            ProcessStartInfo startInfo = new ProcessStartInfo()
            {
                CreateNoWindow = false,
                UseShellExecute = true,
                FileName = executableFilePath,
                WindowStyle = ProcessWindowStyle.Hidden,
                Arguments = "/s /v/qn"
            };
            using (Process exeProcess = Process.Start(startInfo))
            {
                exeProcess.WaitForExit();
                int exitcode = exeProcess.ExitCode;

                if (exitcode == 0)
                {
                    Console.WriteLine("Installation was successfully completed");
                                        }
                else
                    Console.WriteLine("one or more errors occurred during the installation");
            }

        }




void RunSilentSetup(string executableFilePath, string targetDir)
{
 .

 .
    Arguments = "/s /v/qn"+targetDir,
