C# Enumerable over a type gives different options (Finding more options in a function)

Question

What cast or library am I missing to import in the code snippet below? I would like to be able to convert the bytes to arrays.

Example:

1. A.interface=> gives four values at one location vertices.=>values has only four options to choose from

2. A.interface=> gives 30 values at another location. whereas in another class, I have multiple options to be selected.

   public static byte[] GetRGB32Pixels(SampleImage image, out int cwidth, out int cheight) { Sample.imagedatacdata; byte[] cpixels = null; cwidth = cheight = 0; if (image.AcquireAccess(Sample.Imageaccess.ACCESS_READ, Sample.PixelFormat.PIXEL_FORMAT_RGB32, out cdata) >= Sample.Status.STATUS_NO_ERROR) { cwidth = (int)cdata.pitches[0] / sizeof(Int32); cheight = (int)image.Info.height; cpixels = cdata.ToByteArray(0, (int)cdata.pitches[0] * cheight); image.ReleaseAccess(cdata); } return cpixels; }

Can you help me understand? In the above code, I am referring to the SampleImage datatype. If I extend SampleImage instance "image" within the code I am getting only limited options but in another class when I call the same instance of SampleImage I am seeing multiple options.

Answer 1

You have a using System.Linq in the file where you have the extra options. This using brings in several extension methods that help with LINQ (see details on extensions methods here)
