c# - 使用我的资源图像 - Compact Framework

Question

我将图像添加到我的项目资源 (Windows Mobile 6.1)。我想使用此图像来设置我在表单中拥有的某些 PictureBoxes 的 PictureBox.Image 属性。我尝试以下代码:

pictureBox1.Image = Properties.Resources.my_image;
pictureBox2.Image = Properties.Resources.my_image;
pictureBox3.Image = Properties.Resources.my_image;

...

pictureBoxN.Image = Properties.Resources.my_image;

问题是有时图像只显示在某些 PictureBox 中(当我尝试设置图像时出现 TargetInvocationException)，而不是全部显示。为什么？我该如何解决这个问题？

编辑:

InnerException 的 StackTrace:

我的猜测是您的内存或其他资源不足。图片资源有点危险。每次获得资源时，都会创建一个新资源。您可能只想创建一个 my_image 实例，并且可能希望在使用完它后将其丢弃。

Image myImage = Properties.Resources.my_image;

pictureBox1.Image = myImage;
pictureBox2.Image = myImage;
pictureBox3.Image = myImage;
pictureBox4.Image = myImage;
...
pictureBoxN.Image = myImage;

// Later on when you are done using it
myImage.Dispose();

对于大多数 CF 应用来说，不要浪费内存非常重要。
