Question

I am basically developing a software in Visual Studio 2010 .NET 4.0 where in I capture the screenshot from a pc and send it over a network to another.
Since I cannot directly send a Bitmap, I have to convert it to String.
I did a lot of internet search but cant find any solution. 🙁

I found this code on stackoverflow itself.
But it it doesnt work. I tried to print the string (converted from image) but the program behaves like that line doesnt exist.
I used a MessageBox.Show(String);
But not even a msg box pops up!
Can anyone please help? I’m stuck!
Thankx in advance 🙂 (Y)

bitmapString = null;       // Conversion from image to string
MemoryStream memoryStream = new MemoryStream();
bmpScreenshot.Save(memoryStream, ImageFormat.Png);
byte[] bitmapBytes = memoryStream.GetBuffer();
bitmapString = Convert.ToBase64String(bitmapBytes,Base64FormattingOptions.InsertLineBreaks); // Conversion from image to string end

Image img = null;                           //Conversion from string to image
byte[] bitmapBytes = Convert.FromBase64String(rob);
MemoryStream memoryStream = new MemoryStream(bitmapBytes);
img = Image.FromStream(memoryStream);   //Conversion from string to image end

Try to convert it to a byte array:

public static byte[] ImageToByteArray(Image img)
{
    byte[] byteArray = new byte[0];
    using (MemoryStream stream = new MemoryStream())
    {
        img.Save(stream, System.Drawing.Imaging.ImageFormat.Png);
        stream.Close();

        byteArray = stream.ToArray();
    }
    return byteArray;
}

I believe you can simply cast a Bitmap object to an Image object. So Image img = (Image)myBitmap; – then pass that into the method above.
