想获取项目浏览器中出现的所有标准族该用什么条件？

你直接用Family这个类名来获取就可以了。

请看下面代码：

public void GetAllStandardFamilies(){  Application app = this.Application;             Document doc = this.ActiveUIDocument.Document;          FilteredElementCollector collector = new FilteredElementCollector(doc);          collector.OfClass(typeof(Family));          string familyNames = null;                    foreach(Element elem in collector)          {          if(elem is Family)          {          Family f = elem as Family;          familyNames += f.Name + "\r\n";          }                    }          TaskDialog.Show("all families",familyNames);          }
