如果你能帮助我，我将不胜感激。

i need help in converting image(picturebox.resourse) to byte array (byte[]) in WPF
id used this code : but it cannot resolve second line
"Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);"
my code is :
MemoryStream ms = new MemoryStream();
picturebox.Resources.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
byte[] pic_arr = new byte[ms.Length];
ms.Position = 0;
ms.Read(pic_arr, 0, pic_arr.Length);


Please If You can help me I would be grateful.

推荐答案

Bitmap bitmapImage = picturebox.Resourses;
byte[] data;
JpegBitmapEncoder encoder = new JpegBitmapEncoder();
encoder.Frames.Add(BitmapFrame.Create(bitmapImage));
using(MemoryStream ms = new MemoryStream())
{
    encoder.Save(ms);
    data = ms.ToArray();
}

private void GetImage(byte[] pic)
{
byte[] data = (byte[])pic;
MemoryStream strm = new MemoryStream();
strm.Write(data, 0, data.Length);
 
strm.Position = 0;
 
System.Drawing.Image img = System.Drawing.Image.FromStream(strm);
 
BitmapImage bi = new BitmapImage();
 
bi.BeginInit();
 
MemoryStream ms = new MemoryStream();
 
img.Save(ms, ImageFormat.Bmp);
 
ms.Seek(0, SeekOrigin.Begin);
 
bi.StreamSource = ms;
 
bi.EndInit();
 
pbStuPic.Source = bi;
}
 

 

 

we caled like this
 var bits = getJPGFromImageControl(pbStuPic.Source as BitmapImage);

它无法在wpf .net 4.5中解析（bitmapImage）此解决方案

i am using using vsoz>




问题是：

i有主窗体的图片框，我需要把它放在byte []中发送它到数据库

i访问图片框中的图片像这样

picturebox.Resourses = ....

it can not resolve (bitmapImage) this solution in wpf .net 4.5
i am using vs2012


the problem is :
i have picture box in main form and i need to put it in byte[] to send it to database
i access to the picture in picturebox like this
picturebox.Resourses=....
