Help C# Points to Line conversion

Cibi_PranavP_S — Thu, 23 Feb 2017 01:43:26 GMT

I am working on a tool to convert point to line using ArcObjects in C#. I can understand the arcpy function but is there an example to show how to convert a point layer into a line feature and save as a new line layer? Any code snippet will help.#PointsToLine

You could call the existing geo-processing tool, that would be easiest. One way to do this is to be using the IGeoProcessor object and call the tool.

Search the API help there are numerous examples of tools being run using this approach.

This is a portion of the code I used in a tool that converted points (pPointFLayer) to a line (pLineFLayer)

    Dim pPointFLayer As ESRI.ArcGIS.Carto.IFeatureLayer
    Dim pFCursor As ESRI.ArcGIS.Geodatabase.IFeatureCursor
    Dim pFeature As ESRI.ArcGIS.Geodatabase.IFeature
    Dim pFirstPointShape As ESRI.ArcGIS.Geometry.IGeometry
    Dim pFirstPoint As ESRI.ArcGIS.Geometry.IPoint
    Dim pSecondPointShape As ESRI.ArcGIS.Geometry.IGeometry
    Dim pSecondPoint As ESRI.ArcGIS.Geometry.IPoint
    Dim pLine As ESRI.ArcGIS.Geometry.ILine
    Dim pSegColl As ESRI.ArcGIS.Geometry.ISegmentCollection
    Dim pGeomColl As ESRI.ArcGIS.Geometry.IGeometryCollection
    Dim pPolyline As ESRI.ArcGIS.Geometry.IPolyline
    Dim pIFBuffer As ESRI.ArcGIS.Geodatabase.IFeatureBuffer
    Dim pIFCursor As ESRI.ArcGIS.Geodatabase.IFeatureCursor


      pIFCursor = pLineFLayer.FeatureClass.Insert(True)
      pIFBuffer = pLineFLayer.FeatureClass.CreateFeatureBuffer
      pFCursor = pPointFLayer.Search(Nothing, False)
      pFeature = pFCursor.NextFeature

      Do Until pFeature Is Nothing
        FirstGroupID = pFeature.Value(pFeature.Fields.FindField(cboField.Text))
        pFirstPointShape = pFeature.Shape
        pFirstPoint = pFirstPointShape
        pFeature = pFCursor.NextFeature
        If pFeature Is Nothing Then Exit Do

          pSecondPointShape = pFeature.Shape
          pSecondPoint = pSecondPointShape

          pLine = CreateLn(pFirstPoint, pSecondPoint)
          pSegColl = New ESRI.ArcGIS.Geometry.Path
          pSegColl.AddSegment(pLine)
          pGeomColl = New ESRI.ArcGIS.Geometry.Polyline
          pGeomColl.AddGeometry(pSegColl)
          pPolyline = pGeomColl

          pIFBuffer.Shape = pPolyline
          pIFCursor.InsertFeature(pIFBuffer)
      Loop


    Private Function CreateLn(ByRef pPointFrom As ESRI.ArcGIS.Geometry.IPoint, ByVal pPointTo As ESRI.ArcGIS.Geometry.IPoint) As ESRI.ArcGIS.Geometry.ILine
      CreateLn = New ESRI.ArcGIS.Geometry.Line
      CreateLn.PutCoords(pPointFrom, pPointTo)
    End Function
