锁定的图层淡显的程度

Locking the layer through .NET

不知道，这串代码是什么意思

程序代码：


[CommandMethod("Layerlack")]

static public void Layerlack()

{

    Document doc = Application.DocumentManager.MdiActiveDocument;

    Database db = doc.Database;

    Editor ed = doc.Editor;

 

    using (Transaction tr = db.TransactionManager.StartTransaction())

    {

        LayerTable table = tr.GetObject(db.LayerTableId,

                                    OpenMode.ForRead) as LayerTable;

 

        if (table.Has("Test"))

        {

            LayerTableRecord record = tr.GetObject(table["Test"],

                              OpenMode.ForWrite) as LayerTableRecord;

            record.IsLocked = true;

            //rset the line weight Just make layer dirty..

            record.LineWeight = record.LineWeight;

        }

        tr.Commit();

    }

    ed.Regen();

}

但是可以设置系统变量“laylockfadectl” 来调整锁定图层的淡显程度
