╠════╣ ╠══════════════════════════════════════════════════╣ ╚════════╝② 点击下载： 标注：实现新建shapefile文件，部分截图如下！
属性截图如下：
实现步骤：
- 新建工作空间工厂 IWorkspaceFactory！（矢量数据）
- 新建要素工作空间 IFeatureWorkspace！ <IWorkspaceFactory.OpenFromFile()>
- 若指定的文件名存在了，则将其内部的数据删除！ <IDataset.Delete()>
- 为要素集新建字段 IFields！
- 新建要素集 IFeatureClass！ <IFeatureWorkspace.CreateFeatureClass()>
- 新建要素 IFeature！ <IFeatureClass.CreateFeature()>
代码如下：
