推荐答案

您在询问两件不同的事情：

A）调整图像大小是图像处理，与操作图像数据本身的部分无关。您可以使用此处描述的内置方法： http：// tech.pro/tutorial/620/csharp-tutorial-image-editing-saving-cropping-and-resizing [ ^ ]，或更复杂和细粒度的方法，如OpenCV [ ^ ]（更准确地说是 EmguCV [ ^ ]）

B）如何存储图像数据是另一个事。您必须遵循您的应用程序要求来自行决定。我很难想象你真的需要一个不同的表来存储编辑过的图像的情况 - 但是，这种情况可能存在。

You are asking about two different things:
A) Resizing an image is an image manipulation, and has nothing to do with the part where you manipulate the image data itself. You can use the built-in methods like described here: http://tech.pro/tutorial/620/csharp-tutorial-image-editing-saving-cropping-and-resizing[^], or more sophisticated and fine-grained methods like OpenCV[^] (more precisely EmguCV[^])
B) How you store the image data is an other thing. You have to decide yourself by following your application requirements. I can hardly imagine a situation where you really need a different table to store the edited image - still, that scenario might exists.
