C#实现获取当前文件路径的上级路径

界面：

声明：

textBox1.Text为指定文件路径：string path = @"F:ABB-pragramABB工作站ABB StationSystemsSituationalTeaching_CarryHOME";

textBox2.Text为得到的该指定文件路径的上级路径（通过：提取路径按钮实现）

代码：

 1 using System;
 2 using System.Collections.Generic;
 3 using System.ComponentModel;
 4 using System.Data;
 5 using System.Drawing;
 6 using System.IO;
 7 using System.Linq;
 8 using System.Text;
 9 using System.Windows.Forms;
10 
11 namespace 文件路径测试
12 {
13 public partial class Form1 : Form
14 {
15 public Form1()
16 {
17 InitializeComponent();
18 }
19 string path = @"F:ABB-pragramABB工作站ABB StationSystemsSituationalTeaching_CarryHOME";
20 private void button1_Click(object sender, EventArgs e)
21 {
22 DirectoryInfo pathInfo = new DirectoryInfo(path);
23 string newPath = pathInfo.Parent.FullName;
24 this.textBox2.Text = newPath.ToString();
25 }
26 
27 private void Form1_Load(object sender, EventArgs e)
28 {
29 this.textBox1.Text = path.ToString();
30 }
31 }
32 }
