ITerraExplorerObject66 obj = (ITerrainDynamicObject66)sgworld.ProjectTree.GetObject(itemid); 運行時這句報錯“無效的條目”
uj5u.com熱心網友回復：
ITerraExplorerObject66 obj = (ITerrainDynamicObject66)sgworld.ProjectTree.GetObject(itemid);已經強制轉換了，應改為
ITerrainDynamicObject66 obj = (ITerrainDynamicObject66)sgworld.ProjectTree.GetObject(itemid);
