AE+C#通过名称来删除要素类

[csharp] view
plaincopy

//注: 在程序运行中往往有些要素类因为出错而无法删除，这时IDataset.Delete这个方法则无法成功，可以用轻量级的名称对象来完成这个任务。以下为C#+AE10源码。

方法一：

//删除要素类

public static bool DeleteFeatureDataset(IWorkspace ws, string name)

{

if (ws == null || string.IsNullOrEmpty(name))

{

ErrMsg = "工作空间或要素类名称不能为空!";

return false;

}

IFeatureDataset pFeaDataSet;

IEnumDatasetName pEnumDatasetName;

IFeatureWorkspace pFeaWorkspace;

IDatasetName pDatasetName;

try

{

pFeaWorkspace = ws as IFeatureWorkspace;

pEnumDatasetName = ws.get_DatasetNames(esriDatasetType.esriDTFeatureClass ^ esriDatasetType.esriDTFeatureDataset);

pEnumDatasetName.Reset();

pDatasetName = pEnumDatasetName.Next();

while (pDatasetName != null)

{

if (pDatasetName.Type == esriDatasetType.esriDTFeatureDataset)

{

//如果是要素集，则对要素集内的要素类进行查找

IEnumDatasetName pEnumFcName = (pDatasetName as IFeatureDatasetName).FeatureClassNames;

IDatasetName pFcName = pEnumFcName.Next();

while (pFcName != null)

{

if (pFcName.Name.IndexOf(name) >= 0)

{

DeleteByName(pFeaWorkspace, pFcName);

return true;

}

pFcName = pEnumFcName.Next();

}

}

else

{

if (pDatasetName.Name.IndexOf(name) >= 0)

{

DeleteByName(pFeaWorkspace, pDatasetName);

return true;

}

}

pDatasetName = pEnumDatasetName.Next();

}

return false;

}

catch (Exception ex)

{

ErrMsg = ex.Message;

return false;

}

}

//删除名称对象

public static void DeleteByName(IFeatureWorkspace pFeaWorkspace, IDatasetName pDatasetName)

{

IFeatureWorkspaceManage pWorkspaceManager = pFeaWorkspace as IFeatureWorkspaceManage;

pWorkspaceManager.DeleteByName(pDatasetName);

}
方法二：
调用GP工具，datamanagement下的delete工具
ESRI.ArcGIS.DataManagementTools.Delete deleteTool = new ESRI.ArcGIS.DataManagementTools.Delete();

deleteTool.in_data = otherPara[0];

geoProcessor.Execute(deleteTool, null);
