请问下图中，资源管理器中的所有信息我能有方法获取到吗？
主要我是想不用遍历所有元素来一一获取ec属性看是不是我想要的，我就想获取一个ec属性组，把他所对应的元素给直接找出来
我看资源管理器中就有现成的信息，我有没有办法直接获取到，它应该也是通过ec来找元素的，而不是通过元素找ec的吧？
DgnECManager有FindDgnECInstances可以根据ECClass查找对应的ECInstance，获取到的IDgnECInstance下有Element属性可以获取到ECInstance所属的Element。
请问是下列的方法吗？有没有使用的例子啊？它传的几个参数是怎么来的啊？都能通过ECClass得到吗？
我下面的测试代码用FindInstances方法，获取不到任何instance，
而FindDgnECInstances()的上面第一个重载的参数我不知道怎么来的，第二个重载的话要传入ElementAgenda,我并没有具体元素传入
具体怎么才能通过ECClass获取到Instance啊？
//获取当前文件中的所有写有编码信息的元素 并提取信息 var dgnModel = Session.Instance.GetActiveDgnModel(); var dgnFile = Session.Instance.GetActiveDgnFile(); var list1 = DgnECManager.Manager.DiscoverSchemasForModel(dgnModel, ReferencedModelScopeOption.All, false); foreach (var item in list1) { var strs = item.Split('.'); if (strs.Length != 3) { //出错 CustomMessageBox.Show("提取ec属性出错，请联系管理员！", "错误", CustomMessageBoxButton.OK, CustomMessageBoxIcon.Error); return; } int majorVersion; int minorVersion; if (int.TryParse(strs[1], out majorVersion) && int.TryParse(strs[2], out minorVersion)) { FindInstancesScope scope = FindInstancesScope.CreateScope(dgnModel, new FindInstancesScopeOption()); IECSchema schema = DgnECManager.Manager.LocateSchemaInScope(scope, strs[0], majorVersion, minorVersion, SchemaMatchType.Latest); var iecclass1 = schema.GetClass("BMXX"); if(iecclass1 != null) { ECQuery eCQuery = new ECQuery(iecclass1); var instancesList = DgnECManager.Manager.FindInstances(scope, eCQuery); foreach (var ins in instancesList) { CustomMessageBox.Show("获取成功", "提示", CustomMessageBoxButton.OK, CustomMessageBoxIcon.Information); break; } } var iecclass2 = schema.GetClass("SJSX"); if (iecclass2 != null) { ECQuery eCQuery = new ECQuery(iecclass2); var instancesList = DgnECManager.Manager.FindInstances(scope, eCQuery); foreach(var ins in instancesList) { CustomMessageBox.Show("获取成功", "提示", CustomMessageBoxButton.OK, CustomMessageBoxIcon.Information); break; } } } else { //出错 CustomMessageBox.Show("提取ec属性出错，请联系管理员！", "错误", CustomMessageBoxButton.OK, CustomMessageBoxIcon.Error); return; } }
请参考如下代码：
string SchemaName = "TunnelAttributes"; string ClassName = "TunnelCode"; FindInstancesScope scope = FindInstancesScope.CreateScope(Session.Instance.GetActiveDgnModel(), new FindInstancesScopeOption(DgnECHostType.Element)); FindInstancesScope scopeTemp = FindInstancesScope.CreateScope(Session.Instance.GetActiveDgnFile(), new FindInstancesScopeOption()); int verMaj = 01, verMin = 0; IECSchema ecschema = DgnECManager.Manager.LocateSchemaInScope(scopeTemp, SchemaName, verMaj, verMin, SchemaMatchType.Latest); scopeTemp = FindInstancesScope.CreateScope(Session.Instance.GetActiveDgnFile(), new FindInstancesScopeOption()); ecschema = DgnECManager.Manager.LocateSchemaInScope(scopeTemp, SchemaName, verMaj, verMin, SchemaMatchType.Latest); IECClass ecClass = ecschema.GetClass(ClassName); IECClass[] ecClassArr = new IECClass[1]; ecClassArr[0] = ecClass; ECQuery ecQuery = new ECQuery(ecClassArr); DgnECInstanceCollection dgnECInsCol = DgnECManager.Manager.FindInstances(scope, ecQuery); foreach(var curVar in dgnECInsCol) { MessageCenter.Instance.ShowInfoMessage(curVar.Element.ElementId.ToString(), "", false); }

成功了，感谢，
我将之前的FindInstancesScope scope = FindInstancesScope.CreateScope(Session.Instance.GetActiveDgnModel(), new FindInstancesScopeOption());
替换成FindInstancesScope scope = FindInstancesScope.CreateScope(Session.Instance.GetActiveDgnModel(), new FindInstancesScopeOption(DgnECHostType.Element));
就可以成功获取了，那就应该是FindInstancesScopeOption的构造不对的问题了
