ArcGIS 10.1在.NET中使用ArcObjects。我很擅長遍歷要素類中的所有功能。不過,我花了好一整天的時間嘗試尋找一種按字段對功能進行分組的方法。在ArcGIS 10.1中獲取具有相同字段的行
我目前使用的:
Dim pFeatCursor As IFeatureCursor = pPolylineFeatLayer.Search(Nothing, False)
Dim pPolylineFeature As IFeature = pFeatCursor.NextFeature
While Not pPolylineFeature Is Nothing
'do something with the single feature
pPolylineFeature = pFeatCursor.NextFeature
End While
什麼即時試圖做的是:
'group features by fields "CODE3" and "AIDX"
for every group
'dump that group of features to it's own featureclass
next group
我一直在尋找一些光標類和不能似乎找到任何做這種類型的查詢。這個python函數似乎可以做到這一點,但需要在.NET中執行此操作,並且此工具僅在ModelBuilder中可用。
arcpy.IterateFeatureSelection_mb(Input_Features, Group_By_Fields, "false")
試了一下。不適用於shapefile,只適用於geodbs。謝謝你的提示。 – sinDizzy
