把图片保存进数据库的方法基本上都一样把图片转换成BYTE 保存进数据库不分是SILVERLIGHT 还是WPF

silveright是运行在客户端的，你要搞清楚，你的数据库在哪？

OpenFileDialog ofd = new OpenFileDialog();
ofd.Filter = "Image files (*.jpg;*.png)|*.png;*.png | All Files (*.*)|*.*";
ofd.FilterIndex = 1; if (true == ofd.ShowDialog())
{
FileStream fileStream = ofd.File.OpenRead();
BitmapImage bi = new BitmapImage();
bi.SetSource(fileStream);
ImageSource = bi;
byte[] img = File.ReadAllBytes(ofd.Filter);
ContainerData.ContainerPic = img;
fileStream.Close();
}

这样写哪里错了呢
OpenFileDialog ofd = new OpenFileDialog();
ofd.Filter = "Image files (*.jpg;*.png)|*.png;*.png | All Files (*.*)|*.*";
ofd.FilterIndex = 1; if (true == ofd.ShowDialog())
{
FileStream fileStream = ofd.File.OpenRead();
BitmapImage bi = new BitmapImage();
bi.SetSource(fileStream);
ImageSource = bi;
byte[] img = File.ReadAllBytes(ofd.Filter);
ContainerData.ContainerPic = img;
fileStream.Close();
}

你的数据库应该在服务器端的吧，先上传到服务器上
