Type.IsAnsiClass 屬性

定義

取得值,指出是否為 AnsiClass 選取字串格式屬性 Type

public:
 property bool IsAnsiClass { bool get(); };
public bool IsAnsiClass { get; }
member this.IsAnsiClass : bool
Public ReadOnly Property IsAnsiClass As Boolean

屬性值

如果為 true 選取字串格式屬性 AnsiClass,則為 Type,否則為 false

範例

下列範例會取得欄位資訊,並檢查 AnsiClass 屬性。

using namespace System::Reflection;

public:
   MyClass()
   {
      myField =  "A sample protected field";
   }
};

      // Get the type of the 'MyClass'.
      Type^ myType = MyClass::typeid;
      
      // Get the field information and the attributes associated with MyClass.
      FieldInfo^ myFieldInfo = myType->GetField( "myField", static_cast<BindingFlags>(BindingFlags::NonPublic | BindingFlags::Instance) );
      Console::WriteLine( "\nChecking for the AnsiClass attribute for a field.\n" );
      
      // Get and display the name, field, and the AnsiClass attribute.
      Console::WriteLine( "Name of Class: {0} \nValue of Field: {1} \nIsAnsiClass = {2}", myType->FullName, myFieldInfo->GetValue( myObject ), myType->IsAnsiClass );

備註

StringFormatMask 選取字串格式屬性。 字串格式屬性藉由定義應如何解譯字串來增強互通性。

如果目前的 Type 表示泛型型別,則此屬性與建構型別的來源泛型型別定義有關。 例如,如果目前的 Type 代表 MyGenericType<int> Visual Basic) 中的 (MyGenericType(Of Integer) ,則此屬性的值是由 MyGenericType<T> 決定。

如果目前的 Type 表示泛型型別的型別參數,這個屬性一律會傳 false 回 。
