导入shape文件到SDE数据库

/**

       * pDataSet:要导出的数据库的数据集，如果直接导入到数据库而不是数据集，则使用强制转换IWorkspace-->IDataset

       * strFeatFileDir:要导入的shape文件所在目录

       * strFeatFileName:要导入的shape文件名

       * isWorkspace:标识是导入数据库还是数据集

       *strOutName:存储于数据库的文件名  

       *failInfo:导入失败文件名  

       *errorDetail:错误信息  

       *skipInfo:发现重名情况跳过文件名
