Greetings,

I need to do following in c#

/********************************************/

Set oDGN = oMS.OpenDesignFile(strOpen, True)
   Set oView = oDGN.Views(1)
            Set oElScan = New ElementScanCriteria
            oElScan.ExcludeAllColors
 
 
    oElScan.IncludeColor 5
            oElScan.IncludeColor 6
 
  oElScan.ExcludeAllLevels
  oElScan.IncludeLevel oLev
 
Dim Point As Point3d, PVoid As Point3d
 
 
Point.X = ((1034.3 - 1000) * dblMult) + 1000
                            Point.Y = ((1000.9 - 1000) * dblMult) + 1000
                            Point.z = 0#
 
oMS.CadInputQueue.SendCommand "CHOOSE ELEMENT "
    oMS.CommandState.SetLocateCursor
Set oElement = oMS.CommandState.LocateElement(Point, oView, True)
