从picturebox默认图像保存图像（来自资源）

Question

how to save this image into sqlserver, i usually save it from file name but i don't know how to save from resources

Answer 1

Try this:

public byte[] WinImage=new byte[0];
MemoryStream stream = new MemoryStream();
PictureBox.Image.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg);
WinImage=stream.ToArray();

And save it to the table as varbinary(max) . To open the image from database:

MemoryStream stream = new MemoryStream(byte[] WinImage);
Image RetImage = Image.FromStream(stream);
PictureBox.Image = RetImage;

Answer 2

You can convert image to filestream like this,

FileStream fs = new FileStream(dlg.FileName, FileMode.Open, FileAccess.Read);
data = new byte[fs.Length];
fs.Read(data, 0, System.Convert.ToInt32(fs.Length));
fs.Close();

Then you can save the image as byte[] array to your database table where the field datatype is Image .
