Answer 1

 //load bitmap from file
 Image bmp = Image.FromFile();

Graphics g = Graphics.FromImage(bmp);

//do drawing here with g.

bmp.Save();

g.Dispose()

Answer 2

    Bitmap newBitmap = new Bitmap(originalBitmap);
    using (Graphics myGraphics = Graphics.FromImage(newBitmap))
    {
        // draw here on myGraphics
    }
    // newBitmap - modified image

或者使用 Load &节省：

    Bitmap myBitmap = new Bitmap("fileName.bmp");
    using (Graphics myGraphics = Graphics.FromImage(myBitmap))
    {
        // draw here on myGraphics
    }
    myBitmap.Save("newFileName.bmp");
