對(duì)于WINFORM程序，使用 System.Configuration.ConfigurationManager；
對(duì)于ASP.NET 程序， 使用 System.Web.Configuration.WebConfigurationManager；
對(duì)于配置文件內(nèi)容的讀取，真是太普遍不過(guò)了，如果你的程序里，沒(méi)有讀取配置文件內(nèi)容的方面，你都不好意思拿出來(lái)用
我們以最常見(jiàn)的 AppSettings 小節(jié)來(lái)作為例子：
假設(shè)有如下的配置文件內(nèi)容：
復(fù)制代碼 代碼如下:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="y" value="this is Y"/>
</appSettings>
</configuration>
1. 讀取值：
* ASP.NET: System.Web.Configuration.WebConfigurationManager.AppSettings[“y”];
* WinForm: System.Configuration.ConfigurationManager.AppSettings[“y”];
2. 添加一項(xiàng)
ASP.NET(需要有寫(xiě)權(quán)限):
Configuration config = WebConfigurationManager.OpenWebConfiguration(null);
AppSettingsSection app = config.AppSettings;
app.Settings.Add("x", "this is X");
config.Save(ConfigurationSaveMode.Modified);
WinForm:
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
AppSettingsSection app = config.AppSettings;
app.Settings.Add("x", "this is X");
config.Save(ConfigurationSaveMode.Modified);
3. 修改一項(xiàng)
* ASP.NET
Configuration config = WebConfigurationManager.OpenWebConfiguration(null);
AppSettingsSection app = config.AppSettings;
//app.Settings.Add("x", "this is X");
app.Settings["x"].Value = "this is not Y";
config.Save(ConfigurationSaveMode.Modified);
* WinForm
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
AppSettingsSection app = config.AppSettings;
//app.Settings.Add("x", "this is X");
app.Settings["x"].Value = "this is not Y";
config.Save(ConfigurationSaveMode.Modified);
4. 刪除一項(xiàng)
* ASP.NET
Configuration config = WebConfigurationManager.OpenWebConfiguration(null);
AppSettingsSection app = config.AppSettings;
app.Settings.Remove("x");
config.Save(ConfigurationSaveMode.Modified);
* WinForm
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
AppSettingsSection app = config.AppSettings;
app.Settings.Remove("x");
config.Save(ConfigurationSaveMode.Modified);
AspNet技術(shù)：ASP.NET(C#)應(yīng)用程序配置文件app.config/web.config的增、刪、改操作，轉(zhuǎn)載需保留來(lái)源！
