以下代碼旨在重命名 AutoCAD 中的布局選項卡。它總是重命名前 2 個布局選項卡。當我在運行程式之前添加更多選項卡時，它會重命名它們，但會跳過 layout5。當我再次運行程式時，它會重新編號（包括 layout5）。如果之后我添加更多布局，我會收到一個致命錯誤： Unhandeld Acces Violation Reading 0xffffffff exception at 1315DFE3h
有人可以指出正確的方向或可以提示我我做錯了什么嗎？提前致謝。

uj5u.com熱心網友回復：
看起來我們需要遍歷所有布局以首先重繪 TabOrder。這是一個例子。
[CommandMethod("LayRenum")]
public void CmdLayRenum()
{
var doc = Application.DocumentManager.MdiActiveDocument;
var edt = doc.Editor;
var db = doc.Database;
var layoutMgr = LayoutManager.Current;
try
{
using (var trans = db.TransactionManager.StartTransaction())
{
var layoutDict = (DBDictionary)trans.GetObject(db.LayoutDictionaryId, OpenMode.ForRead);
var layouts = layoutDict
.Cast<System.Collections.DictionaryEntry>()
.Select(entry => (Layout)trans.GetObject((ObjectId)entry.Value, OpenMode.ForWrite))
.OrderBy(layout => layout.TabOrder)
.ToArray();
for (int i = 1; i < layouts.Length; i )
{
var layout = layouts[i];
LayoutManager.Current.RenameLayout(layout.LayoutName, $"blad{i:00}");
}
trans.Commit();
}
}
catch (System.Exception ex)
{
edt.WriteMessage("\nError >> " ex.Message);
}
}
