    ' Before running this example, open a code document from a project  
    ' and place the insertion point inside a variable definition.

    }  
    catch (Exception ex)  
    {  
        MessageBox.Show(ex.Message);  
    }  
}  

注解

Access 返回实际的访问权限以及其他代码访问此代码元素的方式。

备注

对于源代码中的代码元素,此属性是只读的 Visual Basic 。

此外,在进行某些类型的编辑之后,代码模型元素(例如类、结构、函数、特性、委托等)的值可能是不确定的,这意味着无法依赖于它们的值始终保持不变。
