遍历IFeatureDataset中的FeatureClass

IFeatureWorkspace m_FeatureWorkspace;
m_FeatureWorkspace=(IFeatureWorkspace)m_SdeWorkSpace;        //将SDE工作空间转换成要素工作空间

IFeatureDataset m_FeatureDataset = m_FeatureWorkspace.OpenFeatureDataset(listBox_DataFiles.SelectedItem.ToString());

//利用IFeatureClassContainer对象遍历IFeatureDataset

IFeatureClassContainer m_FeatureClassContainer = (IFeatureClassContainer)m_FeatureDataset;
IEnumFeatureClass m_EnumFC = m_FeatureClassContainer.Classes;
IFeatureClass m_FeatureClass = m_EnumFC.Next();

while (m_FeatureClass != null)
{
          IFeatureLayer m_FeatureLayer = new FeatureLayerClass();
          m_FeatureLayer.FeatureClass = m_FeatureClass;
          m_MapControl.Map.AddLayer(m_FeatureLayer);   //加载到map窗口

           m_FeatureClass = m_EnumFC.Next();

}
m_MapControl.ActiveView.Refresh();
