WPF BitmapImage内存 [英] WPF BitmapImage Memory

问题描述

我目前正在使用C＃WPF中的位图图像，我遇到了以下问题，我希望有人可以提供帮助。下面的代码是我如何将位图图像分配给位图，然后分配给ImageControl。问题在于我将这段代码用于许多位图图像并且它们似乎留在内存中......如何以正确的方式从内存中删除位图图像。请帮助！

Hi, I am currently working with Bitmap Images in C# WPF, and I have run into the following problem and I was hoping someone could help. the code below is how I assign a bitmap image to a bitmap and then to a ImageControl. The problem comes in that im using this code for many bitmap images and they seem to stay in memory... How do I remove bitmap images from memory the correct way. Please Help!

BitmapImage logo = new BitmapImage();
          logo.BeginInit();
          logo.CreateOptions = BitmapCreateOptions.IgnoreColorProfile;
          logo.UriSource = new Uri(f.FullName);
          displayImage.Source = logo;
          logo.EndInit();

提前致谢：）

Thanks in advance :)

推荐答案

通过在我的项目中添加以下代码，



logo.DecodePixelWidth = 100;

logo.DecodePixelHeight = 100;



它工作得更好，并且在使用大约700张图像时更加内存友好：）

By adding the following Code to my project,

logo.DecodePixelWidth = 100;
logo.DecodePixelHeight = 100;

it works alot better and is alot more memory friendly when using around about 700 images :)

BitmapImage imageDocumento = new BitmapImage （）;

imageDocumento.BeginInit（）;

imageDocumento.UriSource = new Uri（@c：\ image.png）;

imageDocumentoDA1.CacheOption = BitmapCacheOption.OnLoad;

imageDocumentoDA1.EndInit（）;

BitmapImage imageDocumento = new BitmapImage();
imageDocumento.BeginInit();
imageDocumento.UriSource = new Uri(@"c:\image.png");
imageDocumentoDA1.CacheOption = BitmapCacheOption.OnLoad;
imageDocumentoDA1.EndInit();
