如何仅限制.cor文件添加到列表中。下面的代码允许将.corx，.corxx，.corxxx添加到列表中。我只想要.cor文件。这可能吗？

private void btn_models_Click(object sender, EventArgs e)
        {
            DialogResult res = dlg_find_folder.ShowDialog();
            if (res == DialogResult.OK)
            {
                tbx_models.Text = dlg_find_folder.SelectedPath;

                populateChecklist(tbx_models.Text, "cor");
                cbx_all.CheckState = System.Windows.Forms.CheckState.Checked;
            }
        }

        /// <summary>
        /// Function populates the models checklist based on the models found in the specified folder.
        /// </summary>
        /// <param name="directory">Directory in which to search for files</param>
        /// <param name="extension">File extension given without period</param>
        private void populateChecklist(String directory, String extension)
        {
            clb_run_list.Items.Clear();

            System.Collections.IEnumerator enumerator;
            String mdl_name;

            try
            {
                enumerator = System.IO.Directory.GetFiles(directory, "*." + extension).GetEnumerator();

                while (enumerator.MoveNext())
                {
                    mdl_name = parse_file_name((String)enumerator.Current, directory, extension);
                    clb_run_list.Items.Add(mdl_name);
                }
            }
            catch
            {
                //above code will fail if the initially specified directory does not exist
                //MessageBox.Show("The specified directory does not exist. Please select a valid directory.");
            }

            return;
        }

Answer 1

怎么样;

if (Path.GetExtension(mdl_name).Equals(".cor", StringComparison.OrdinalIgnoreCase))
  clb_run_list.Items.Add(mdl_name);

Answer 2

在添加到您的列表之前检查FileName.EndsWith(extension)？

Answer 3

这是Windows支持旧DOS 8.3文件名的工件。扩展名为.corxxx的文件会映射到像Blah~1.cor这样的8.3名称。并且会匹配您的通配符。

你无能为力，只需仔细检查你得到的文件名。使用Path.GetExtension（）

文件扩展名限制为.color（仅限）
