[求助]如何批量处理一个目录下的所有DWG文件
本帖最后由 作者 于 2010-9-28 19:16:50 编辑如题，如下代码
public void BatchAddTitle()
{
string patch = @"C:\Documents and Settings\ABC\桌面\test\";
try
{
string[] dirs = Directory.GetFiles(patch, "*.dwg");
//创建文件夹
string newFolder = "转换后";
if (!Directory.Exists(patch + newFolder))
{
Directory.CreateDirectory(patch + newFolder);
}
foreach (string item in dirs)
{
ed.WriteMessage(item + "\n");
try
{
Document doc = Application.DocumentManager.Open(item, false);
//执行一系列操作,比如一个addTitle函数，接受Document参数。
DocumentLock doclock = doc.LockDocument();
addTitle(doc);
doclock.Dispose();
//改文件名
string newFileName = Path.GetDirectoryName(item) + "\\" + newFolder + "\\" + Path.GetFileName(item);
//存储的文件版本
//doc.Database.SaveAs(newFileName, DwgVersion.Current);
ed.WriteMessage("newFileName:<" + newFileName + ">");
//doc.CloseAndSave(newFileName);
}
catch (System.Exception ex)
{
ed.WriteMessage("内：" + ex.Message + ":" + ex.StackTrace + "\n");
}
}
}
catch (System.Exception ex)
{
ed.WriteMessage("外：" + ex.Message + "\n");
}
}
打开test文件夹下的DWG文件后，addTitle(doc)也没有报错，但是没有预期后的执行效果；
如下处理单个文件：
public void bxcl()
{
Document doc = Application.DocumentManager.MdiActiveDocument;
addTitle(doc);
}
可以正常执行。
加上参数CommandFlags.Session以后，程序可以正常运行，感谢lzh741206的指点
但是我觉得即使不加CommandMethod 的参数CommandFlags.Session程序也应该能够正常运行啊。
我感觉即使在一个session里面，打开操作其他Document并保存也是可行的，但是根据我代码的实际运行情况来看不可行。
我的代码哪里有问题？
对于cad的session正确理解是什么？
谁能给个打开某一目录下所有的dwg文件并处理的例子啊？ 是不是要用到长事务？ <font face="Verdana"></font> 本帖最后由 作者 于 2010-9-28 19:05:25 编辑 <br /><br /> lzh741206发表于2010-9-27 17:54:00static/image/common/back.gif
<p></p>一言中的啊<br/>问题解决，看来我的要去了解示例方法和静态方法的知识了<br/>我还是想知道我那代码不能运行的详细原因。<br/> <table class="Table4" cellspacing="0">
