ArcEngine获取mdb下要素类FeatureClass,独立要素类,没有dataset获取要素类

功能说明

ArcEngine获取mdb下要素类FeatureClass,独立要素类,没有dataset获取要素类

获取mdb数据库要素类的名称


1.通过IWorkspace的Datasets属性获取工作空间中的所有Dataset对象(IEnumDataset)
2.枚举EnumDataset,获取Dataset对象
3.如果该Dataset是FeatureDataset
4.QI到IFeatureClassContainer接口
for(int i=0;i < pFClContainer.ClassCount;i++)
{
???IFeatureClass pFeatureClass= pFClContainer.Class(i);
???IDataset pDataset = pFeatureClass as IDataset;
???string pFeaClsName= pDataset.Name;
???……
}

获取独立于要素数据集的要素类

///   
/// 获取独立的要素类  
///   
/// 工作空间下任意一个要素数据集  
/// 独立要素类的名称  
/// 找的的独立要素类  
private IFeatureClass PRV_GetIndependentFeatureClass(IFeatureDataset IN_SomeFeatureDataset,string IN_FeatureClassName)  
{  
        //获取所有独立的要素类  
        IEnumDataset Temp_AllIndependentFeatureClass=(IN_SomeFeatureDataset.Workspace.get_Datasets(esriDatasetType.esriDTFeatureClass));  
        //获取每一个独立的要素类  
        IFeatureClass Each_IndependentFeatureClass = Temp_AllIndependentFeatureClass.Next() as IFeatureClass;  
        //遍历所有要素类  
        while (Each_IndependentFeatureClass != null)  
        {  
            //如果找到了就返回  
            if (Each_IndependentFeatureClass.AliasName==IN_FeatureClassName)  
                return Each_IndependentFeatureClass;  
        }  
        return null;  
}
