.NET有COM的CopyObjects吗？找到方法了！

本帖最后由 作者 于 2009-9-21 1:43:08 编辑 <br /><br /> <p>com有object.CopyObjects(Objects[, Owner][, IDPairs]) ，object是<a href="mk:@MSITStore:E:\New%20Study\CAD\acadautovba.chm::/idh_database_object.htm">Database</a>, <a href="mk:@MSITStore:E:\New%20Study\CAD\acadautovba.chm::/idh_document_object.htm">Document</a>用于将一个document的图形复制到另外一个document当中，而且在 CopyObjects 操作期间，被 Objects 参数中的源对象拥有或引用的对象也将被复制。</p><p>不知道.net有没有相同功能的函数？查看了对象浏览器的document和database对象，都没有类似的方法</p>

<p>找到方法了！</p><p>使用WblockCloneObjects</p><p>注意红色的部分，不过不知道能不能复制块参照，并且把块参照的引用块定义也一起复制过去，com里的copyobjects方法可是可以做到这一点的，我试验过。<br/>&nbsp;</p><pre class="codeLine">using Autodesk.AutoCAD.Runtime;</pre><pre

<p>还有深度Clone</p><p>db.DeepCloneObjects(...)</p>

gsteven 发表于 2009-9-21 19:27:00

<p>深度clone有什么不一样吗？</p>

雪山飞狐_lzh 发表于 2009-9-21 19:43:00

<p>深层拷贝-复制数据</p><p>浅层拷贝-只复制引用</p><p>具体的要在使用的过程中去理解它</p>
