CShaper 窗口程序选择文件 文件夹

1、C#  MFC 窗口程序

        private void btn_selectPath_Click(object sender, EventArgs e)
        {
            System.Windows.Forms.OpenFileDialog dialog = new OpenFileDialog();
            //该值确定是否选择多个文件
            dialog.Multiselect = true;
            dialog.Title = "select folder";
            dialog.Filter = "txt(*.*)|*.txt|files|*.c";
            if(dialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                lab_Path.Text = dialog.FileName;
            }
        }

以上是选择文件的代码

 

其中dialog.Filter中  Filter示例：

//表示分文件选择使用‘|’分割
dialog.Filter = "txt(*.*)|*.txt|files|*.c";

//多个选择使用 ';' 分割  表示可以选择这几中类型的文件
dialog.Filter = "allpexl(*.xls,*.xlxs)|*.xls;*.xlsx";

 

选择文件夹

        private void btn_selectfolder_Click(object sender, EventArgs e)
        {
            //使用System.Windows.Forms.FolderBrowserDialog选择文件夹
            System.Windows.Forms.FolderBrowserDialog dialog = new FolderBrowserDialog();
            dialog.Description = "select";
            if(dialog.ShowDialog() == DialogResult.OK)
            {
                if (string.IsNullOrEmpty(dialog.SelectedPath))
                {
                    System.Windows.Forms.MessageBox.Show(this, "文件夹不能为空", "Done");
                }
                else
                {
                    System.Windows.Forms.MessageBox.Show(this, dialog.SelectedPath, "Done");
                }
            }
        }
