我用了
private BitmapImage byteArrayToImage(byte[] byteArrayIn)
{
try
{
MemoryStream stream = new MemoryStream();
stream.Write(byteArrayIn, 0, byteArrayIn.Length);
stream.Position = 0;
System.Drawing.Image img = System.Drawing.Image.FromStream(stream);
BitmapImage returnImage = new BitmapImage();
returnImage.BeginInit();
MemoryStream ms = new MemoryStream();
img.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp);
ms.Seek(0, SeekOrigin.Begin);
returnImage.StreamSource = ms;
returnImage.EndInit();
return returnImage;
}
catch (Exception ex)
{
throw ex;
}
return null;
}
在我的应用程序中,此方法将字节数组转换为图像。但是它抛出“参数无效”异常。为什么会发生..?有其他替代方法吗??
最佳答案
嗨,这应该工作:
private static BitmapImage LoadImage(byte[] imageData)
{
if (imageData == null || imageData.Length == 0) return null;
var image = new BitmapImage();
using (var mem = new MemoryStream(imageData))
{
mem.Position = 0;
image.BeginInit();
image.CreateOptions = BitmapCreateOptions.PreservePixelFormat;
image.CacheOption = BitmapCacheOption.OnLoad;
image.UriSource = null;
image.StreamSource = mem;
image.EndInit();
}
image.Freeze();
return image;
}
关于c# - 在wpf中将字节数组转换为图像,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/9564174/
