Web與WinForm關於web.config的讀取

寫Web長了，忘了WinForm關於 web.Config 的讀寫了，找了一下，自己寫出來比較比較

以AppSettings爲例說明：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="pis" value="xxxx"/>
  </appSettings>
</configuration>

1。讀取

web：       System.Web.Configuration.WebConfigurationManager.AppSettings["pis"]; 

winform： System.Configuration.ConfigurationManager.AppSettings["pis"];

2。添加

web：

Configuration config = WebConfigurationManager.OpenWebConfiguration(null);
AppSettingsSection appSettings = config.AppSettings;
appSettings.Settings.Add("pp", "pppppp");
config.Save(ConfigurationSaveMode.Modified);

winform：

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
AppSettingsSection appSettings = config.AppSettings;
appSettings.Settings.Add("pp", "pppppp");
config.Save(ConfigurationSaveMode.Modified);

3。修改

web：

Configuration config = WebConfigurationManager.OpenWebConfiguration(null);
AppSettingsSection appSettings = config.AppSettings;
appSettings.Settings["pp"].Value = "qqqqqq";
config.Save(ConfigurationSaveMode.Modified);

winform：

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
AppSettingsSection appSettings = config.AppSettings;
appSettings.Settings["pp"].Value = "qqqqqq";
config.Save(ConfigurationSaveMode.Modified);

4。刪除

web：

onfiguration config = WebConfigurationManager.OpenWebConfiguration(null);
AppSettingsSection appSettings = config.AppSettings;
appSettings.Settings.Remove("pp");
config.Save(ConfigurationSaveMode.Modified);

winform：

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
AppSettingsSection appSettings = config.AppSettings;
appSettings.Settings.Remove("pp");
config.Save(ConfigurationSaveMode.Modified);

當然還可以在配置文件裏面寫關於web.config的讀寫操作，用到的類稍微有些區別。

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        ......
    </configSections>
    <applicationSettings>
        <Winform1.Properties.Settings>
            <setting name="pp" serializeAs="String">
                <value>pppppp</value>
            </setting>
        </Winform1.Properties.Settings>
    </applicationSettings>
</configuration>

如果在winform中用

string connStr = Properties.Settings.Default.pp;即可讀取
