在ftp服务器上删除文件？

Question

i am trying to delete a file from my FTP website but i cannot seem to get the code to work could anyone help?, i get no error's it just doesn't do anything.

private FtpWebRequest deleteRequest(string uri, string method)
{
    var r = (FtpWebRequest)WebRequest.Create(uri);
    string Delete = WebRequestMethods.Ftp.DeleteFile;

    r.Credentials = new NetworkCredential(TxtUsername.Text, TxtPassword.Text);
    r.Method = Delete = listView1.SelectedItems.ToString();
    return r;
}

The rest of the code.

    private void openToolStripMenuItem_Click(object sender, EventArgs e)
    {
        textBox1.Text = TxtServer.Text + listView1.SelectedItems.ToString();
        deleteRequest(textBox1.Text, WebRequestMethods.Ftp.DeleteFile);
    }

Answer 1

You have to call r.GetResponse() . You really don't need to return your request from your method.

Answer 2

You are overwriting the "DELETE" method with whatever is selected in your ListView.

---

The following line:

r.Method = Delete = listView1.SelectedItems.ToString();

is the same as these two:

Delete = listView1.SelectedItems.ToString();
r.Method = Delete;

So that Delete first gets the value of whatever is in your SelectedItems , and then you use that value as the Method . That's probably not what you had in mind.

Answer 3

This is the code i ended up using thank you all for the help really appreciate it.

private void deleteToolStripMenuItem_Click(object sender, EventArgs e)
    {
        ResultLabel.Text = "Deleting: " + listView1.SelectedItems[0].Text;
        ResultLabel.Show();
        this.Refresh();
        textBox1.Text = TxtServer.Text + listView1.SelectedItems[0].Text;
        FtpWebRequest request = (FtpWebRequest)WebRequest.Create(textBox1.Text);
        request.Method = WebRequestMethods.Ftp.DeleteFile;

        request.Credentials = new NetworkCredential(TxtUsername.Text, TxtPassword.Text);
        FtpWebResponse response = (FtpWebResponse)request.GetResponse();
        ResultLabel.Text = "Deleted: " + listView1.SelectedItems[0].Text;
        response.Close();
    }

I just fully rewrote the code and tried again and it worked.
