下面列举一些常用编辑工具的实现方法。 1、获取所选要素的属性及赋值
// 获取当前所选择的要素
var selectedFeatures MapView.Active.Map.GetSelection();
// 获取所选要素中的第一个取单个要素
var firstSelectionSet selectedFeatures.ToDictionary().First();
// 创建【inspector】实例
var inspector new Inspector();
// 将选定要素加载到【inspector】实例
inspector.LoadAsync(firstSelectionSet.Key, firstSelectionSet.Value);
// 获取要素属性或字段值
string xzmc inspector[XZMC].ToString();
var myGeometry inspector.Shape;
// 给字段赋值
inspector[XZMC] 清凉镇;
// 执行编辑操作
inspector.ApplyAsync();
2、通过【inspector】获取字段属性
// 获取所选要素
var firstFeatureLayer MapView.Active.Map.GetLayersAsFlattenedList().OfTypeFeatureLayer().FirstOrDefault();
// 创建【inspector】实例
var inspector new Inspector();
// 将选定要素加载到【inspector】实例
inspector.LoadSchema(firstFeatureLayer);// 查看属性
foreach (var attribute in inspector)
{var fldName attribute.FieldName; // 字段名称var fldAlias attribute.FieldAlias; // 字段别名var fldType attribute.FieldType; // 字段类型int idxFld attribute.FieldIndex; // 字段序号var fld attribute.GetField(); // 字段var isNullable attribute.IsNullable; // 是否可为空var isEditable attribute.IsEditable; // 是否可编辑var isVisible attribute.IsVisible; // 是否可见var isSystemField attribute.IsSystemField; // 是否系统字段var isGeometryField attribute.IsGeometryField; // 是否几何属性字段var fldLength attribute.Length; // 字段长度
}
3、裁剪面
// 创建编辑器
var clipFeatures new EditOperation();
clipFeatures.Name Clip Features;
// 执行
clipFeatures.Clip(featureLayer, oid, clipPoly, ClipMode.PreserveArea);
if (!clipFeatures.IsEmpty)
{var result clipFeatures.Execute();
}
4、用线分割面
// 获取分割线
var select MapView.Active.SelectFeatures(clipPoly);
// 创建编辑器
var cutFeatures new EditOperation();
cutFeatures.Name Cut Features;// 执行要素类通过oid选择出要素
cutFeatures.Split(featureLayer, oid, cutLine);
// 执行要素则直接使用
cutFeatures.Split(sset, cutLine);if (!cutFeatures.IsEmpty)
{var result cutFeatures.Execute();
}
5、对所选的线要素进行平行复制
// 找到图层作模板用
var roadsLayer MapView.Active.Map.FindLayers(Roads).FirstOrDefault();// 建立【平行复制生成器】并设置参数
var parOffsetBuilder new ParallelOffset.Builder()
{Selection MapView.Active.Map.GetSelection(), // 所选要素Template roadsLayer.GetTemplate(Freeway), // 模板可以不选Distance 200, // 偏移距离Side ParallelOffset.SideType.Both, // 偏移方式左右两侧Corner ParallelOffset.CornerType.Mitered, // 拐角处理方式圆角斜接角斜面角Iterations 1, // 重复偏移的次数AlignConnected false, // 是否对齐连接线的方向CopyToSeparateFeatures false, // 是否复制到独立要素RemoveSelfIntersectingLoops true // 是否移除自相交环
};// 创建编辑器并执行
var parallelOp new EditOperation();
parallelOp.Create(parOffsetBuilder);
if (!parallelOp.IsEmpty)
{var result parallelOp.Execute();
}
6、删除要素
var deleteFeatures new EditOperation();
deleteFeatures.Name Delete Features;
// 删除表中的某一行
var table MapView.Active.Map.StandaloneTables[0];
deleteFeatures.Delete(table, oid);// 删除所选要素
var selection MapView.Active.SelectFeatures(polygon);
deleteFeatures.Delete(selection);if (!deleteFeatures.IsEmpty)
{var result deleteFeatures.Execute();
}
7、全属性复制一个要素并移位
// 创建编辑器
var duplicateFeatures new EditOperation();
duplicateFeatures.Name Duplicate Features;
// 创建【inspector】实例
var insp2 new Inspector();
// 加载
insp2.Load(featureLayer, oid);
// 获取几何
var geom insp2[SHAPE] as Geometry;
// 复制要素
var rtoken duplicateFeatures.Create(insp2.MapMember, insp2.ToDictionary(a a.FieldName, a a.CurrentValue));
if (!duplicateFeatures.IsEmpty)
{if (duplicateFeatures.Execute()){// 移动位置var modifyOp duplicateFeatures.CreateChainedOperation();modifyOp.Modify(featureLayer, (long)rtoken.ObjectID, GeometryEngine.Instance.Move(geom, 100.0, 100.0));if (!modifyOp.IsEmpty){var result modifyOp.Execute();}}
}
8、炸开多部件
var explodeFeatures new EditOperation();
explodeFeatures.Name Explode Features;
// 执行
explodeFeatures.Explode(featureLayer, new Listlong() { oid }, true);
if (!explodeFeatures.IsEmpty)
{var result explodeFeatures.Execute();
}
9、合并要素
var mergeFeatures new EditOperation();
mergeFeatures.Name Merge Features;// 创建【inspector】实例
var inspector new Inspector();
// 加载
inspector.Load(featureLayer, oid);
// 执行
mergeFeatures.Merge(featureLayer, new Listlong() { 5, 6, 7 }, inspector);if (!mergeFeatures.IsEmpty)
{var result mergeFeatures.Execute();
}
10、更新单个要素
var modifyFeature new EditOperation();
modifyFeature.Name Modify a feature;// 创建【inspector】实例
var modifyInspector new Inspector();
// 加载
modifyInspector.Load(featureLayer, oid);// 更改属性【包括几何属性】
modifyInspector[SHAPE] polygon;
modifyInspector[NAME] Updated name;
// 更新
modifyFeature.Modify(modifyInspector);// 涉及更改几何要素的情况
var featureAttributes new Dictionarystring, object();
featureAttributes[NAME] Updated name;// 更改属性
modifyFeature.Modify(featureLayer, oid, polygon, featureAttributes);if (!modifyFeature.IsEmpty)
{var result modifyFeature.Execute();
}
11、更新多个要素
// 通过筛选获取要更新的要素
var queryFilter new QueryFilter();
queryFilter.WhereClause OBJECTID 1000000;
// 获取筛选结果的oid
var oidSet new Listlong();
using (var rc featureLayer.Search(queryFilter))
{while (rc.MoveNext()){using (var record rc.Current){oidSet.Add(record.GetObjectID());}}
}// 创建编辑器
var modifyFeatures new EditOperation();
modifyFeatures.Name Modify features;
modifyFeatures.ShowProgressor true;
// 创建【inspector】实例
var muultipleFeaturesInsp new Inspector();
muultipleFeaturesInsp.Load(featureLayer, oidSet);
muultipleFeaturesInsp[MOMC] 24;
// 更新
modifyFeatures.Modify(muultipleFeaturesInsp);
if (!modifyFeatures.IsEmpty)
{var result modifyFeatures.ExecuteAsync();
}
12、筛选要素并更新
// 筛选
var filter new ArcGIS.Core.Data.QueryFilter();
filter.WhereClause CONTRACTOR KCGM;
// 获取所选的oid
var oids new Listlong();
using (var rc disLayer.Search(filter))
{while (rc.MoveNext()){using (var record rc.Current){oidSet.Add(record.GetObjectID());}}
}var modifyOp new ArcGIS.Desktop.Editing.EditOperation();
modifyOp.Name Update date;// 执行
var dateInsp new ArcGIS.Desktop.Editing.Attributes.Inspector();
dateInsp.Load(disLayer, oids);
dateInsp[InspDate] 9/21/2013;modifyOp.Modify(insp);
if (!modifyOp.IsEmpty)
{var result modifyOp.Execute();
}
