FieldInfo.IsPinvokeImpl 属性

获取一个值，该值指示是否已在 FieldAttributes 中设置相应的 PinvokeImpl 属性 (Attribute)。

**命名空间:**System.Reflection
**程序集:**mscorlib（在 mscorlib.dll 中）

语法

声明
Public ReadOnly Property IsPinvokeImpl As Boolean
用法
Dim instance As FieldInfo
Dim value As Boolean

value = instance.IsPinvokeImpl

public bool IsPinvokeImpl { get; }

public:
virtual property bool IsPinvokeImpl {
    bool get () sealed;
}

/** @property */
public final boolean get_IsPinvokeImpl ()

public final function get IsPinvokeImpl () : boolean

属性值

如果在 FieldAttributes 中设置了 PinvokeImpl 属性 (Attribute)，则为 true；否则为 false。

示例

下面的示例创建一个类，并显示名称、字段以及字段的 IsPinvokeImpl 属性 (Property) 值。
