我创建了一个程序来监视目录中的文件发生了什么。例如,如果我添加一个新文件,它会显示新文件的路径和名称。尽管我在 Windows 窗体中对其进行了编码,但我想将其更改为控制台应用程序,以便在控制台上显示结果
我的问题是如何使用控制台浏览文件夹?任何想法提前谢谢
Windows 窗体代码如下:
private void button1_Click(object sender, EventArgs e)
{
DialogResult result = folderBrowserDialog1.ShowDialog();
if (result == DialogResult.OK)
{
button1.Enabled = false;
button2.Enabled = true;
directoryPath = folderBrowserDialog1.SelectedPath;
}
}
private void button2_Click(object sender, EventArgs e)
{
try
{
if (Directory.Exists(directoryPath))
{
textbox_append("monitor opened");
filesList = Directory.GetFiles(directoryPath);
timer1.Start();
}
else
{
MessageBox.Show("folder does not exist.");
}
}
catch (Exception ex)
{
MessageBox.Show("Error." + ex.Message);
}
}
这是我的全部代码

public string directoryPath;
string[] filesList, filesListTmp;
