<span>可以通过调用DynAnyFactory对象上的操作来创建DynAny对象。</span>
<span>通常只有两种方法来创建DynAny对象：</span>
<ul>
<li> <span>调用对现有DynAny对象的操作</span> </li>
<li> <span>在DynAnyFactory对象上调用操作</span> </li>
</ul>
<span>构造的DynAny对象支持操作，可以创建新的DynAny对象，这些对象封装了对某些组件的值的访问。</span>
<span>DynAny对象还支持复制操作来创建新的DynAny对象。</span>
<span>通过调用ORB.resolve_initial_references（）将标识符参数设置为字符串常量“DynAnyFactory”获得对DynAnyFactory对象的引用。</span>
<p> <span>任何动态解释通常涉及使用create_dyn_any（）作为第一步创建DynAny对象。</span> <span>根据任何类型，可以将生成的DynAny对象引用缩小为DynFixed，DynStruct，DynSequence，DynArray，DynUnion，DynEnum或DynValue对象引用。</span> </p>
<p> <span>任何动态创建涉及使用create_dyn_any_from_type_code（）创建DynAny对象，传递与要创建的值相关联的TypeCode。</span> <span>返回的引用被缩小为一个复杂类型，如DynStruct（如果适用）。</span> <span>然后，可以通过调用对结果对象的操作来初始化该值。</span> <span>最后，可以调用to_any操作以从构造的DynAny创建任何值。</span> </p>

<span>基本类型的默认值为：</span>
