return value from class

labbylabby Posts: 10Member
Hi,

I want get return value from a class and call it from the main programming code, 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.Format64bppPArgb);

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();

    Hello,

    Seems like you have a class and a function in that class which have the same names.
    Example:
    You have class ScanFirstStage and function ScanFirstStage in that class.

    I hope it helps!
