I was testing how I can use dotspatial to import ERSI shapefile
I can import streetname to Mtext

this is another sample where I was try to import Polyline but dont know how to finish it
if Someone has good knowledge in .net how to use dotspatial to import Polyline

Public Sub importsample()


End Sub

Public Sub importSHP(ByVal path_file) ' This method can have any name

Dim zwDoc As Document = Application.DocumentManager.MdiActiveDocument
Dim ZWEd As Editor = Application.DocumentManager.MdiActiveDocument.Editor

Dim shapeActual As FeatureSet = FeatureSet.Open(path_file)

Dim dt As System.Data.DataTable = shapeActual.DataTable
For row As Integer = 0 To dt.Rows.Count - 1

Dim x = (CStr(shapeActual.Features.Item(row).Centroid.Envelope.X))
Dim y = (CStr(shapeActual.Features.Item(row).Centroid.Envelope.Y))
Dim Comment As Object = dt.Rows(row)("TEXTSTRING")
Dim angle As Object = dt.Rows(row)("ANGLE")

Dim turn As String
turn = Replace(angle, ",", ".")

If Not IsDBNull(Comment) Then
Dim db As Database = Application.DocumentManager.MdiActiveDocument.Database
Using acTrans As Transaction = db.TransactionManager.StartTransaction()

Dim acBlkTbl As BlockTable = acTrans.GetObject(db.BlockTableId, OpenMode.ForRead)

Dim acBlkTblRec As BlockTableRecord
acBlkTblRec = acTrans.GetObject(acBlkTbl(BlockTableRecord.ModelSpace), OpenMode.ForWrite)

Dim acMText As MText = New MText()
acMText.Location = New Point3d(x, y, 0)

acMText.Attachment = AttachmentPoint.MiddleCenter

acMText.TextHeight = 2
acMText.Contents = Comment
acMText.Layer = 0

acMText.Normal = Vector3d.ZAxis

acMText.Rotation = turn * Math.PI / 180.0
acTrans.AddNewlyCreatedDBObject(acMText, True)


End Using
End If

zwDoc.SendStringToExecute("_zoom e ", True, False, False)

End Sub
