Hi,

I want get return value from a class and call it from the main programming, but it return error. The error is :

‘ScanFirstStage’: members name cannot be same as their enclosing type.
Could any help me please?

This is the class that suppose return the value -->

---------------------------------------------------------------------
        public int ScanFirstStage (Bitmap image, out int cb)
        {

            // get image size
            int width = image.Width;
            int height = image.Height;

            pixels = width * height;
            // lock bitmap data
BitmapData imgData = image.LockBits(new Rectangle(0, 0, width, height),ImageLockMode.ReadOnly,PixelFormat.Format6 4bppPArgb);

                int srcStride = imgData.Stride;
                int srcOffset = srcStride - width;


            // do the job
            unsafe

            {
                byte* p = (byte*)imgData.Scan0.ToPointer();
                int i = 0;

                for (int y = 0; y < height; y++)
                {
                    for (int x = 0; x < width; x++)
                    {
                            if (*p == 0)
                            {
                                i++;
                            }

                            ++p;
                        }

                        p += srcOffset;
                    }

                     cb = i;
            }

            // unlock image data
            image.UnlockBits(imgData);

        }
------------------------------------------------------------------

This is the code from mainform to call the return value -->

ClassFirstStage.ScanFirstStage filter3 = new ClassFirstStage.ScanFirstStage(binary, out scanning1);
            //apply filter for extraction
            double scan1 = filter3.ScanFirstStage;
            int num1 = (int)scan1;
            objectCount1.Text = num1.ToString();

Your class is called ScanFirstStage and so is one of its methods. This is not allowed, try calling the method Scan or something similar. ScanFirstStage is a strange name for a class, if you are following Microsoft guidelines then classes should be noun or noun phrases, Scanner, for example.
