bitmap image.How can i access picture box in loaddata class?

推荐答案

最好的方法是将图像返回到函数中的表单. br/>
在您的loaddata类中，创建一个加载图像并返回图像的函数.

在表单类中，调用该函数并将图像放在图片框中.

这是最好的方法，因为您将表单与数据类分开，并将图像的加载与表单分开.

如果您需要更多详细信息，请随时在评论中寻求更详细的答案.

The best way to do that would be to return the image to the form in the function.

In your loaddata class, create a function that load the image and return it.

In your form class, call the function and put the image in the picture box.

That''s the best way to do it because you separate the form from your data class and you separate the loading of the image from your form.
