打开对话框保存对话框

1.打开对话框

            FolderBrowserDialog openFileDialog1 = new FolderBrowserDialog();
            openFileDialog1.Description = "(*.gdb)|*.gdb";
            DialogResult pDialogResult = openFileDialog1.ShowDialog();
            if (pDialogResult != DialogResult.OK)
                return;
            string pPath = openFileDialog1.SelectedPath;
         
            string pFileName = System.IO.Path.GetFileName(pPath);

2.保存对话框

            SaveFileDialog saveFileDialog1 = new SaveFileDialog();
            saveFileDialog1.Filter = "文本文件 (*.txt)|*.txt|所有文件 (*.*)|*.*"; //删选、设定文件显示类型
            saveFileDialog1.FilterIndex = 2;//设置默认文件类型显示顺序
            saveFileDialog1.RestoreDirectory = true;//保存对话框是否记忆上次打开的目录
            //saveFileDialog1.AutoUpgradeEnabled = false;//改了对话框的样式
            DialogResult dr = saveFileDialog1.ShowDialog();
            if (dr == DialogResult.OK)
            {
                string path = saveFileDialog1.FileName;
            }
            saveFileDialog1.Dispose();
            string filePath = saveFileDialog1.FileName;//上面是保存文件对话框

3.选择路径

   // 选择路径
        private string SelectPath()
        {
            string path = string.Empty;
            System.Windows.Forms.FolderBrowserDialog fbd = new System.Windows.Forms.FolderBrowserDialog();
            if (fbd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                path = fbd.SelectedPath;
            }
            return path;
        }
