Hi,i'm posting question for first time so if i dnt follow any threads or any mistake please excuse me...

Im getting this error in my code:
"Object reference not set to an instance of an object."

Here is my code:

C#
 void document_PrintPage(object sender, PrintPageEventArgs e)
        {
            
            e.Graphics.DrawImage(_memoryImage, 0, 0);

        }
        private Bitmap _memoryImage;

        private void CaptureScreen()
        {
            // put into using construct because Graphics objects do not 
            //  get automatically disposed when leaving method scope
            using (var myGraphics = CreateGraphics())
            {
                var s = Size;
                _memoryImage = new Bitmap(1500, 1000, myGraphics);
                using (var memoryGraphics = Graphics.FromImage(_memoryImage))
                {
                    printDocument2.DefaultPageSettings.PaperSize = new System.Drawing.Printing.PaperSize("PaperA4", 826, 1169);
                    memoryGraphics.CopyFromScreen(Location.X, Location.Y, 70, 30, s);
                }
            }
        }

        private void printDocument2_PrintPage(object sender, PrintPageEventArgs e)
        {
             //calculate width and height scalings taking page margins into account
            var wScale = e.MarginBounds.Width / (float)_memoryImage.Width;
            var hScale = e.MarginBounds.Height / (float)_memoryImage.Height;

            // choose the smaller of the two scales
            var scale = wScale < hScale ? wScale : hScale;

            // apply scaling to the image
            e.Graphics.ScaleTransform(scale, scale);

            // print to default printer's page
            e.Graphics.DrawImage(_memoryImage, 70, 30);
            printDocument2.DefaultPageSettings.PaperSize = new System.Drawing.Printing.PaperSize("PaperA4", 826, 1169);
        }
private void btnprintpre_Click(object sender, EventArgs e)
        {
            //Associate PrintPreviewDialog with PrintDocument.
            printPreviewDialog1.Document = printDocument2;

            // Show PrintPreview Dialog
            //printPreviewDialog1.ShowDialog();

            printPreviewDialog1.WindowState = FormWindowState.Maximized;
            printPreviewDialog1.ShowDialog();
        }


And i'm getting near "var wScale = e.MarginBounds.Width / (float)_memoryImage.Width;"

So if anyone has come across this error or can solve my problem please help me.

e.MarginBounds.Width or (float)_memoryImage.Width is returning null to the statement thats why you have error

Look at the variables again. Which ones can be null?
e, e.MarginBounds, memoryImage: they are reference types
but surely not
e.MarginBounds.Width or _memoryImage.Width: they are value types.
debug your code and check whether _memoryImage variable is assigned some value or not.

Its a good practice to check for object value before using its properties.

like

if(_memoryImage != null)
{
//write your whole code here
}

My problem got solved by changing the normal buttons to menu buttons and putting the code in it but i'm facing another error now,
