示例：在应用程序中通过“选项”改变程序中的控制
选择CheckBox，为其Checked属性设置ApplicationSettings。
此操作会
1.自动在Properties中的Settings.settings中添加两个属性值：CloseDocumentPrompt和CloseBatchPrompt。
[global::System.Configuration.UserScopedSettingAttribute()]
[global::System.Diagnostics.DebuggerNonUserCodeAttribute()]
[global::System.Configuration.DefaultSettingValueAttribute("True")]
public bool CloseDocumentPrompt {
get {
return ((bool)(this["CloseDocumentPrompt"]));
}
set {
this["CloseDocumentPrompt"] = value;
}
}
[global::System.Configuration.UserScopedSettingAttribute()]
[global::System.Diagnostics.DebuggerNonUserCodeAttribute()]
[global::System.Configuration.DefaultSettingValueAttribute("True")]
public bool CloseBatchPrompt {
get {
return ((bool)(this["CloseBatchPrompt"]));
}
set {
this["CloseBatchPrompt"] = value;
}
}
2.会自动生成App.config文件，其内容为：
＜?xml version="1.0" encoding="utf-8" ?＞
＜configuration＞
＜configSections＞
＜sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" ＞
＜section name="Sample.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" /＞
＜/sectionGroup＞
＜/configSections＞
＜userSettings＞
＜Sample.Properties.Settings＞
＜setting name="CloseDocumentPrompt" serializeAs="String"＞
＜value＞True＜/value＞
＜/setting＞
＜setting name="CloseBatchPrompt" serializeAs="String"＞
＜value＞True＜/value＞
＜/setting＞
＜/Sample.Properties.Settings＞
＜/userSettings＞
＜/configuration＞
