记录最后一次打开位置?

[money_live]

rt

namespace WindowsFormsApplicationAppconfig {
	public partial class Form1 : Form {
		public Form1() {
			InitializeComponent();
			Application.ApplicationExit += new EventHandler(Application_ApplicationExit);
		}

		/// <summary>
		/// 保存最后一次打开文件夹路径
		/// </summary>
		void Application_ApplicationExit(object sender, EventArgs e) {
			Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
			config.AppSettings.Settings.Add("fbdSelectedPath", this.folderBrowserDialog1.SelectedPath);
			config.Save(ConfigurationSaveMode.Modified);
		}

		private void btOpen_Click(object sender, EventArgs e) {
			this.folderBrowserDialog1.SelectedPath = ConfigurationManager.AppSettings["fbdSelectedPath"];
			if (this.folderBrowserDialog1.ShowDialog() == DialogResult.OK) {
				// Todo......
			}
		}
	}
}

不能保存?

[money_live]

	public partial class Form1 : Form {
		public Form1() {
			InitializeComponent();
			Application.ApplicationExit += new EventHandler(Application_ApplicationExit);
		}

		/// <summary>
		/// 保存最后一次打开文件夹路径
		/// </summary>
		void Application_ApplicationExit(object sender, EventArgs e) {
			Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
			config.AppSettings.Settings.Add("fbdSelectedPath", this.folderBrowserDialog1.SelectedPath);
			config.Save(ConfigurationSaveMode.Modified);
			ConfigurationManager.RefreshSection("appSettings");// 后面再添的
		}

		private void btOpen_Click(object sender, EventArgs e) {
			this.folderBrowserDialog1.SelectedPath = ConfigurationManager.AppSettings["fbdSelectedPath"];
			if (this.folderBrowserDialog1.ShowDialog() == DialogResult.OK) {
				// Todo......
			}
		}
	}

在运行时的状态:发现 有写入,关闭后,就没了

[money_live]

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings>
<add key="fbdSelectedPath" value="F:\,E:\" />
</appSettings>
</configuration>

app.config(bin/debug下的)
最后代码变成这样
先是打开一次f盘,在打开一次E:

在写入记录前, 将fbdSelectedPath的value值先清空.
