Manipulate offset profile parameters

[serpetfree]

I'm trying to manipulate offset profile parameters. But nothing happens.
I can read offset profile parameters, but I can't write or remove.

I have Civil 3D 2022.1.1 Update.

I'm not sure I'm using it right, I don't know what I'm doing wrong, I'm trying 3 different ways. Why doesn't any of them work?

Here is my code snippet VB .NET:

Dim docCol As Autodesk.AutoCAD.ApplicationServices.DocumentCollection = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager
        Dim db As Database = docCol.MdiActiveDocument.Database

        Dim tr As Transaction = db.TransactionManager.StartTransaction()
        Dim ln As Long
        Dim lnProf As Long
        Dim id As ObjectId
        Dim idProf As ObjectId
        
        ln = Convert.ToInt32(alignmentHANDLE, 16)
        lnProf = Convert.ToInt32(profileHANDLE, 16)

        Dim hn As New Handle(ln)
        Dim hnProf As New Handle(lnProf)
    
            id = db.GetObjectId(False, hn, 0)
            Dim pl As Alignment = tr.GetObject(id, OpenMode.ForWrite) 'get offset alignmet

            idProf = db.GetObjectId(False, hnProf, 0)
            Dim plProf As Profile = tr.GetObject(idProf, OpenMode.ForWrite) 'get offset profile

            Dim staDouble As Double
            Dim slopeDouble As Double

            staDouble = 600
            slopeDouble = 0.05

            Dim Prof_Parameters As New Profile.OffsetProfileParameters(plProf)
            Dim Param_station As New Profile.OffsetProfileParametersStation(staDouble, slopeDouble, "test1")

            'method 1
            Prof_Parameters.Stations.Add(Param_station)
            'method 2
            Prof_Parameters.Stations.Insert(Prof_Parameters.Stations.Count, Param_station)

            'method 3
            staDouble = 700
            slopeDouble = 0.05
            Param_station.Station = staDouble
            Param_station.Slope = slopeDouble
            Param_station.Description = "test2"

            plProf.OffsetParameters.Stations.Add(Param_station)

            tr.Commit()
            tr.Dispose()

hi

look at this is link

Thank you I have seen this page, but it's not working for me, I don't know.

plProf is Profile
Param_station is Profile.OffsetProfileParametersStation

But this is not working:
plProf.OffsetParameters.Stations.Add(Param_station)

In my visual studio :
ReadOnly Property Profile.Offsetparameters As Profile.OffsetProfileParameters

I don't understand.

I've attached a Visual Studio printscreen

can you read this is

Thanks for your help, problem solved.
