Hello,
I am trying to call a specific method ("Open") from the .NET assembly.The .NET
assembly along with all other .dlls and necessary files, can be downloaded from
here. It's free an open source project: MapWindow.
In their examples page, by loading the Interop.MapWinGIS.dll file, they call
the MapWinGIS.Shapefile.Open() method like so:
using MapWinGIS;
string shpfilename = "C:/example.shp";
Shapefile sf = new Shapefile();
if (sf.Open(shpfilename, null))
{
}
However, when I try the same thing in ironpython:
import clr
import os
shpfilename = "C:/example.shp"
dllsfilename = "C:/mapwindow_dlls"
clr.AddReferenceToFileAndPath(os.path.join(dllsfilename,
"Interop.MapWinGIS.dll"))
print "Interop.MapWinGIS.dll loaded: ", "Interop.MapWinGIS" in
[assembly.GetName().Name for assembly in clr.References] # prints: True
import MapWinGIS
sf = MapWinGIS.Shapefile() # raises Error
sf.Open(shpfilename, None)
I am getting an error message:
"Message: Cannot create instances of Shapefile because it is abstract"
Why is this happening?
I contacted the author of the project, but couldn't solve the issue.
Any kind of advice would be helpful.
Kind regards,
Djordje Spasic
