Type.IsAnsiClass 屬性
重要
部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
取得值，指出是否為 AnsiClass 選取字串格式屬性 Type。
public:
property bool IsAnsiClass { bool get(); };C#
public bool IsAnsiClass { get; }member this.IsAnsiClass : boolPublic ReadOnly Property IsAnsiClass As Boolean如果為 true 選取字串格式屬性 AnsiClass，則為 Type，否則為 false。
下列範例會取得欄位資訊，並檢查 AnsiClass 屬性。

會 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 。
