IWorkspace操作

1、创建工作空间

 	public static IWorkspace CreateWorkspace(string pName, string pPath)
        {
            IWorkspaceFactory workspaceFactory = null;
            Type factoryType = Type.GetTypeFromProgID("esriDataSourcesGDB.AccessWorkspaceFactory");
            workspaceFactory = (IWorkspaceFactory)Activator.CreateInstance(factoryType);
            Directory.CreateDirectory(pPath);
            IWorkspaceName workspaceName = workspaceFactory.Create(pPath, pName,null, 0);
            IName Name = (IName)workspaceName;
            _workSpaceInstance = (IWorkspace)(Name.Open());
            return _workSpaceInstance;
        }

2、创建要素集

   <span style="white-space:pre">	</span> public static IFeatureDataset CreateFeatureDataSet(/*string name,ISpatialReference srf*/)
        {
            IFeatureDatasetDialog fdlg = new FeatureDatasetDefDialog();
            IFeatureWorkspace featureWorkspace = (IFeatureWorkspace)_workSpaceInstance;
            return fdlg.DoModalCreate(featureWorkspace, 0);
        }

3、删除要素集

 <span style="white-space:pre">	</span>public static void DeleteFeatureDataSet(string name)
        {
            IFeatureDataset fds = GetFeatureDataSet(name);
            if (fds != null)
                fds.Delete();
        }

4、获取数据库中的IFeatureDataset

  <span style="white-space:pre">	</span>public static IFeatureDataset GetFeatureDataSet(string name)
        {
            if (_workSpaceInstance == null) return null;
            IFeatureWorkspace featureWorkspace = (IFeatureWorkspace)_workSpaceInstance;
            IFeatureDataset tmp = featureWorkspace.OpenFeatureDataset(name);
            return tmp;
        }

5、重命名DataSet

 <span style="white-space:pre">	</span>public static void RenameFeatureDataSet(IFeatureDataset fds,string newname)
        {
            if (fds.CanRename())
            {
                fds.Rename(newname);
            }
        }

6、

     /// <summary>
        /// 获取FeatureClass从IFeatureDataset
        /// </summary>
        /// <param name="featDs"></param>
        /// <param name="className"></param>
        /// <returns></returns>
        public static IFeatureClass GetFeatureClassFromFeatureDataset(IFeatureDataset featDs, string className)
        {
            IFeatureClass featClass;
            IFeatureClassContainer fcContainer = featDs as IFeatureClassContainer;
            for (int i = 0; i < fcContainer.ClassCount; i++)
            {
                featClass = fcContainer.get_Class(i);
                if (RuleDBCreater.GetFeatureClassName(featClass) == className)
                {
                    return featClass;
                }
            }
            return null;
        }

7、重命名Dataset

      public static void RenameFeatureClass(IFeatureClass fc,string newname)
        {
            IDataset ds = fc as IDataset;
            if (ds.CanRename())
            {
                ds.Rename(newname);
            }
        }
