问题描述
这是在命令行窗口中显示布局列表的简单命令:
public void TestVP()
{
try
{
_AcAp.Document acDoc = _AcAp.Application.DocumentManager.MdiActiveDocument;
_AcDb.Database acCurDb = acDoc.Database;
_AcEd.Editor editor = _AcAp.Application.DocumentManager.MdiActiveDocument.Editor;
using (_AcDb.Transaction acTrans = _AcDb.Hostapplicationservices.WorkingDatabase.TransactionManager.StartTransaction())
{
_AcDb.BlockTable acBlkTbl;
acBlkTbl = acTrans.Getobject(acCurDb.BlockTableId,_AcDb.OpenMode.ForRead) as _AcDb.BlockTable;
foreach(_AcDb.ObjectId id in acBlkTbl)
{
_AcDb.BlockTableRecord btRecord = (_AcDb.BlockTableRecord)acTrans.Getobject(id,_AcDb.OpenMode.ForRead);
if(btRecord.IsLayout)
{
_AcDb.Layout acLayout = (_AcDb.Layout)acTrans.Getobject(btRecord.LayoutId,_AcDb.OpenMode.ForRead);
editor.WriteMessage(acLayout.LayoutName + "\n");
}
}
acTrans.Commit();
}
}
catch (System.Exception ex)
{
_AcAp.Application.ShowAlertDialog(
string.Format("\nError: {0}\nStacktrace: {1}",ex.Message,ex.StackTrace));
}
}
目前它还包括模型布局。我不想这样。如何将布局列表限制为图纸空间布局?
即使我像这样使用 LayoutManager
:
using (_AcDb.Transaction acTrans = _AcDb.Hostapplicationservices.WorkingDatabase.TransactionManager.StartTransaction())
{
_AcDb.DBDictionary layoutDic = acTrans.Getobject(acCurDb.LayoutDictionaryId,_AcDb.OpenMode.ForRead) as _AcDb.DBDictionary;
foreach(_AcDb.DBDictionaryEntry entry in layoutDic)
{
_AcDb.ObjectId layoutId = entry.Value;
_AcDb.Layout layout = acTrans.Getobject(layoutId,_AcDb.OpenMode.ForRead) as _AcDb.Layout;
editor.WriteMessage(String.Format("{0}--> {1}",Environment.NewLine,layout.LayoutName));
}
acTrans.Commit();
}
我仍然得到:
Active Layout is : Model Number of Layouts is : 3
--> Layout1
--> Layout2
--> Model
我不想针对“Model”的布局名称进行测试。
解决方法
这是我想出来的:
public void TestVP()
{
try
{
_AcAp.Document acDoc = _AcAp.Application.DocumentManager.MdiActiveDocument;
_AcDb.Database acCurDb = acDoc.Database;
_AcEd.Editor editor = _AcAp.Application.DocumentManager.MdiActiveDocument.Editor;
_AcDb.LayoutManager layoutMgr = _AcDb.LayoutManager.Current;
editor.WriteMessage(String.Format("{0}Active Layout is : {1}",Environment.NewLine,layoutMgr.CurrentLayout));
editor.WriteMessage(String.Format("{0}Number of Layouts is : {1}",layoutMgr.LayoutCount));
using (_AcDb.Transaction acTrans = _AcDb.HostApplicationServices.WorkingDatabase.TransactionManager.StartTransaction())
{
_AcDb.BlockTable bt = acCurDb.BlockTableId.GetObject(_AcDb.OpenMode.ForRead) as _AcDb.BlockTable;
_AcDb.BlockTableRecord ms = acTrans.GetObject(bt[_AcDb.BlockTableRecord.ModelSpace],_AcDb.OpenMode.ForRead) as _AcDb.BlockTableRecord;
_AcDb.DBDictionary layoutDic = acTrans.GetObject(acCurDb.LayoutDictionaryId,_AcDb.OpenMode.ForRead) as _AcDb.DBDictionary;
foreach(_AcDb.DBDictionaryEntry entry in layoutDic)
{
_AcDb.ObjectId layoutId = entry.Value;
_AcDb.Layout layout = acTrans.GetObject(layoutId,_AcDb.OpenMode.ForRead) as _AcDb.Layout;
editor.WriteMessage(String.Format("{0}--> {1}",layout.LayoutName));
_AcDb.BlockTableRecord layoutBlkTbl = acTrans.GetObject(layout.BlockTableRecordId,_AcDb.OpenMode.ForRead) as _AcDb.BlockTableRecord;
if(layoutBlkTbl.Id != ms.Id)
editor.WriteMessage(" (PaperSpace)");
}
acTrans.Commit();
}
}
catch (System.Exception ex)
{
_AcAp.Application.ShowAlertDialog(
string.Format("\nError: {0}\nStacktrace: {1}",ex.Message,ex.StackTrace));
}
}
我得到的输出是:
Active Layout is : Model
Number of Layouts is : 3
--> Layout1 (PaperSpace)
--> Layout2 (PaperSpace)
--> Model
我只是将 Layout 的 Id
与 Model Space 对象 Id
的 case
进行比较。可能有更简单的方法。但至少我现在可以将我的列表限制为仅纸张空间布局。
