WPF笔记

在后台给image souce赋值：

1.imgContent.Source =new BitmapImage(new Uri("Content.jpg", UriKind.Relative));

2.// 读取图片源文件到byte[]中 BinaryReader binReader = new BinaryReader(File.Open(strPath, FileMode.Open));

FileInfo fileInfo = new FileInfo(strPath);

byte[] bytes = binReader.ReadBytes((int)fileInfo.Length); binReader.Close(); // 将图片字节赋值给BitmapImage

BitmapImage bitmap = new BitmapImage();

bitmap.BeginInit(); bitmap.StreamSource = new MemoryStream(bytes);

bitmap.EndInit(); // 最后给Image控件赋值

imgV3.Source = bitmap;
