对IFeatureClass进行Join后，如果获取关联Table后的属性表？

【解决办法】：
通过IDisplayTable.DisplayTable获取Join后的Table。

private IFeatureClass FeatureJoinTableFon(IFeatureLayer mFeatureLayer, ITable mTable, string mFeatureField, string mTableField) 

{ 

IFeatureClass inputFeatureClass = mFeatureLayer.FeatureClass; 

ITable FeatureTable = inputFeatureClass as ITable; 

IMemoryRelationshipClassFactory memoryRelClassFactory = new MemoryRelationshipClassFactory(); 

IRelationshipClass relationshipClass = memoryRelClassFactory.Open(test, FeatureTable as IObjectClass, mFeatureField, mTable as IObjectClass, mTableField, Forwardfield, Backwardfield, esriRelCardinality.esriRelCardinalityOneToOne); 

IRelationshipClassCollectionEdit pRelClassCollEdit = mFeatureLayer as IRelationshipClassCollectionEdit; 

pRelClassCollEdit.AddRelationshipClass(relationshipClass); 

IDisplayTable displayTable = pRelClassCollEdit as IDisplayTable; 

IFeatureClass outputFeatureClass = displayTable.DisplayTable as IFeatureClass; 

return outputFeatureClass; 

}

IDisplayRelationshipClass DisplayRelationshipClass = mFeatureLayer as IDisplayRelationshipClass;
 DisplayRelationshipClass.DisplayRelationshipClass(relationshipClass, ESRI.ArcGIS.Geodatabase.esriJoinType.esriLeftInnerJoin);
和这个有什么区别啊，感觉用pRelClassCollEdit没有说明连接方式
用这个代码返回的好像还是没有连接之前的
