來自文件的BitmapSource

Question

如何從圖像文件加載BitmapSource？

Answer 1

您可以從磁盤讀取圖像的字節到一個字節數組，然後創建您的BitmapImage對象。

var stream = new MemoryStream(imageBytes); 
var img = new System.Windows.Media.Imaging.BitmapImage(); 

img.BeginInit(); 
img.StreamSource = stream; 
img.EndInit(); 

return img; 

Answer 2

的代碼如下：

FileStream fileStream = 
    new FileStream(fileName, FileMode.Open, FileAccess.Read); 

var img = new System.Windows.Media.Imaging.BitmapImage(); 
img.BeginInit(); 
img.StreamSource = fileStream; 
img.EndInit(); 

Answer 3

這個工作對我來說：

BitmapSource bSource = new BitmapImage(new Uri("c:\\image.bmp")); 
BitmapImage bImage = new BitmapImage(new Uri("c:\\image.bmp"));
