.NET
2.0中,WinForm应用程序的配置已经非常方便。默认情况下,我们可以利用Properties文件夹里默认的Settings.setting文件进行Application和User两个层级配置信息的设置。在Settings.setting里进行的修改保存后,均自动在后部cs文件里自动生成相关代码,同时在应用程序配置文件(app.config)里存储相关信息。比如,我们在TestWinForm项目里对Settings.setting进行如下修改:
保存后,Settings.Designer.cs文件自动增加如下代码:

要在具体代码中使用配置信息就非常非常的方便了。
1
private void button1_Click(object sender, EventArgs e)
2
{
3
string msg = TestWinForm.Properties.Settings.Default.Server + ":" + TestWinForm.Properties.Settings.Default.Port.ToString();
4
MessageBox.Show(msg);

OK,鬼扯了这么多,用意在于让我们再熟悉下.NET2.0的配置。现在,我们不满足他所提供的默认配置,于是我们创建了自己的一个Demo用的配置类 FtpSetting。在WinForm应用程序里,一切配置类都得继承自 ApplicationSettingsBase 类。
1
sealed class FtpSettings : ApplicationSettingsBase
2
{
3
[UserScopedSetting]
4
[DefaultSettingValue("127.0.0.1")]
5
public string Server
6
{
7
get { return (string)this["Server"]; }
8
set { this["Server"] = value; }
9
}
10![](https://www.cnblogs.com/Images/OutliningIndicators/InBlock.gif)
11
[UserScopedSetting]
12
[DefaultSettingValue("21")]
13
public int Port
14
{
15
get { return (int)this["Port"]; }
16
set { this["Port"] = value; }
17
}
18
}

如果要使用上述配置类,可以用:
1
private void button2_Click(object sender, EventArgs e)
2
{
3
FtpSettings ftp = new FtpSettings();
4![](https://www.cnblogs.com/Images/OutliningIndicators/InBlock.gif)
5
string msg = ftp.Server + ":" + ftp.Port.ToString();
6
MessageBox.Show(msg);

好,似乎还在鬼扯。这个Tip已经进入尾声了,主题正式登场。:) 我们在使用上述 FtpSetting 配置时,当然要先进行赋值保存,然后再使用,后面再修改,再保存,再使用。
1
private void button2_Click(object sender, EventArgs e)
2
{
3
FtpSettings ftp = new FtpSettings();
4
ftp.Server = "ftp.test.com";
5
ftp.Port = 8021;
6![](https://www.cnblogs.com/Images/OutliningIndicators/InBlock.gif)
7
ftp.Save();
8
ftp.Reload();
9![](https://www.cnblogs.com/Images/OutliningIndicators/InBlock.gif)
10
string msg = ftp.Server + ":" + ftp.Port.ToString();
11
MessageBox.Show(msg);
12

嗯。已经Save了,你可能会在应用程序文件夹里找不到它到底保存到哪里去了。由于我们是用UserScope的,所以其实该配置信息是保存到了你的Windows的个人文件夹里去了。比如我的就是 C:\Documents and Settings\brooks\Local Settings\Application Data\TestWinForm目录了。哈~当作Tip吧,免得大伙一时找不到Save后的配置文件。
