Question

您好，AutoCAD C＃大师，我在这里有这段代码，用于打开图形，更改某些图层并关闭，但是在完成图形并关闭之后，在与我创建的dwg相同的文件夹中有一个名为 DocName.dwl 的文件无法关闭autocad无法删除。

有没有可以放开锁的地方，我没有用？

    [CommandMethod("Test", CommandFlags.UsePickSet | CommandFlags.Redraw | CommandFlags.Session | CommandFlags.Modal)]
    public void Test()
    {
        var DocList = AskUserToSelectDocs();
        foreach (string FileName in DocList.Files)
        {
            Application.DocumentManager.Open(FileName, false);
            Document zcDoc = Application.DocumentManager.MdiActiveDocument;
            Database zcDB = zcDoc.Database;

            using (DocumentLock acLckDoc = zcDoc.LockDocument())
            {
                using (Transaction ZcTran = zcDoc.TransactionManager.StartTransaction())
                {
                    BlockTable zcBLT = (BlockTable)ZcTran.GetObject(zcDB.BlockTableId, OpenMode.ForWrite);
                    BlockTableRecord zcBLTR = (BlockTableRecord)ZcTran.GetObject(zcBLT[BlockTableRecord.ModelSpace], OpenMode.ForWrite);

                    zcBLTR.UpgradeOpen();
                    var editor = zcDoc.Editor;

                    var SelectionSet = editor.SelectAll().Value;

                    foreach (ObjectId Objeto in SelectionSet.GetObjectIds())
                    {
                        Entity ent = ZcTran.GetObject(Objeto, OpenMode.ForWrite) as Entity;
                        if (ent is Viewport)
                        {
                            var VP = ent as Viewport;
                            VP.Layer = "Defpoints";
                        }
                    }

                    editor.Regen();

                    ZcTran.Commit();
                }

            }

            zcDB.SaveAs(zcDB.Filename, zcDB.OriginalFileVersion);
            zcDoc.CloseAndSave(zcDoc.Name);
            zcDoc.Dispose();
        }
    }

编辑：现在完整的代码

谢谢！

对于这样的事情，无需打开文档。我建议只将数据库加载到内存中，进行操作，然后保存。所有这些都将在“ DocumentManager”之外。非常适合提高性能，尤其是随着要处理的文件数量的增加。

当前打开的文档并不重要，只要它不是正在处理的文档之一即可（您可以检查）。

尝试一下：

public static void Test()
{
    var DocList = AskUserToSelectDocs();
    //save working db reference
    Database originalDB = HostApplicationServices.WorkingDatabase;
    foreach (string FileName in DocList.Files)
    {
        //a little trick here:
        //construct the database in memory, and read in the target file.
        //now your database is your working database, not the active doc!!
        using (Database database = new Database(false, true))
        {
            database.ReadDwgFile(FileName, System.IO.FileShare.ReadWrite, true, string.Empty);
            HostApplicationServices.WorkingDatabase = database;//important!
            using (Transaction transaction = database.TransactionManager.StartTransaction())
            {
                //do your stuff
            }
            //reset WorkingDB to original db
            HostApplicationServices.WorkingDatabase = originalDB;
            database.SaveAs(FileName, DwgVersion.Current);
        }
    }
}
