获取一个值，指示是否需要声明此 ConfigurationSectionGroup 对象。
Public ReadOnly Property IsDeclarationRequired As Boolean
Dim instance As ConfigurationSectionGroup Dim value As Boolean value = instance.IsDeclarationRequired
public bool IsDeclarationRequired { get; }
public: property bool IsDeclarationRequired { bool get (); }
/** @property */ public boolean get_IsDeclarationRequired()
public function get IsDeclarationRequired () : boolean
如果需要声明此 ConfigurationSectionGroup，则为 true；否则为 false。
下面的代码示例确定是否需要声明 ConfigurationSectionGroup 的此实例。
Console.WriteLine((getSpacer() + _ "Is Group Required?: " + _ sectionGroup.IsDeclarationRequired.ToString()))
Console.WriteLine(getSpacer() + "Is Group Required?: " + sectionGroup.IsDeclarationRequired);
