我有一个程序需要删除完整目录，但我收到private void timer1_Tick(object sender, EventArgs e)
{
label1.Text = DateTime.Now.ToString("HH:mm");
string lowDir = "";
if (label1.Text == comboBox1.Text)
{
try
{
if (System.IO.Directory.GetDirectories(txpath1.Text).Length != 0)
{
try
{
var folders = Directory.GetDirectories(@"" + txpath1.Text);
DateTime lastLow = DateTime.Now;
foreach (string subdir in Directory.GetDirectories(@"" + txpath1.Text))
{
DirectoryInfo fi1 = new DirectoryInfo(subdir);
fi1.Refresh();
DateTime created = fi1.LastWriteTime;
if (created < lastLow)
{
lowDir = subdir;
lastLow = created;
}
}
var dir = new DirectoryInfo(@"" + lowDir);
Directory.Delete(@"" + lowDir, true);
}
catch (Exception ex)
{
this.btStop.PerformClick();
MessageBox.Show(ex.Message+"\nEzért a program leállt.");
}
finally
{
timer1.Stop();
timer2.Start();
}
}
else
{
this.btStop.PerformClick();
MessageBox.Show("A megadott elérési útvonalon nem találhatóak fájlok a művelet(ek)hez!");
}
}
catch (DirectoryNotFoundException)
{
btStop.PerformClick();
MessageBox.Show("Hibás útvonala(kat)t adtál meg!");
}
}
}
错误。我完全可以访问所有人，但它没有帮助。

您只需要使用Directory.Delete(path, true)递归删除。如果这不起作用，则很可能是一条畸形的道路。
