Arcgis Engine(ae)接口详解(1):featureClass
作者:互联网
//IFeatureClass 来源请自行解决 IFeatureClass featureClass = null; //获取featureClass的各种名称 //PS:featureClass可以as到IDataset,因此不能只看接口名,并不是只有数据集才实现IDataset接口 IDataset dataset = featureClass as IDataset; //理论上Name和BrowseName都是名称,在很多情况下都是一样的,在什么时候一样我也无法完全总结,一般可以优先用Name string name = dataset.Name; string browseName = dataset.BrowseName; //别名 string aliasName = featureClass.AliasName; //去掉sde用户名的名称,因为如果是sde的featureClass,名称前会带所属的sde用户名,例如:sde.road,那经过处理后会返回road string nameWithoutSdeName = FeatureClassHelper.GetDatasetNameWithOutSDEUser(dataset); //几何类型,包括点(point)线(polyline)面(polygon)等 esriGeometryType geometryType2 = featureClass.ShapeType; //wordspace,可以获得featureClass所在的worksapce IWorkspace wordspace = dataset.Workspace; //wordspace,可以获得featureClass所在的数据集,如果featureClass不在数据集内,此属性返回null IFeatureDataset featureDataset = featureClass.FeatureDataset; //oid字段的字段名 string oidFieldName = featureClass.OIDFieldName; //几何字段的字段名 string shapeFieldName = featureClass.ShapeFieldName; //IGeoDataset是几何相关的接口 IGeoDataset geoDataset = featureClass as IGeoDataset; //featureClass的范围 IEnvelope envelope = geoDataset.Extent; //空间参考 ISpatialReference spatialReference2 = geoDataset.SpatialReference;
