Answer 2

拖一个folderBrowserDialog1控件，然后就可以通过this.folderBrowserDialog1.SelectedPath获得路径。
如： private void button1_Click(object sender, EventArgs e)
        {
            if (this.folderBrowserDialog1.ShowDialog() == DialogResult.OK)
            {
                string path = this.folderBrowserDialog1.SelectedPath;
                MessageBox.Show(path + "");
            }
        }

            }
