IplImage img = cvlib.cvLoadImage(image_name, cvlib.CV_LOAD_IMAGE_COLOR);
String imageData = Marshal.PtrToStringAnsi(img.imageData);

AsmSearchDll(out nlandmarks, out landmarks, image_name, imageData, img.width, img.height, 1, null, null);

You didn’t specified cvPolyLine… so I can’t check arguments. Anyway… you are just passing wrong value types to your method. As simple as this.
