I can't seem to convert it. Any help?

推荐答案

这是两个完全不同的对象：

They are two completely different objects:

• System.Web.UI.WebControls.Image 是具有呈现HTML，这将使得浏览器下载和显示图像任命的能力控制


• 为System.Drawing.Image 是具有将图像加载到内存中以便操纵它，或者以显示它的能力的类在控制（但不是Web图像控制）。

• System.Web.UI.WebControls.Image is a control that has the ability to render HTML which will make the browser download and display an appointed image
• System.Drawing.Image is a class that has the ability to load an image into memory for manipulating it, or to display it in a control (but not the web image control).

因此，不幸的是没有办法，你可以转换 System.Web.UI.WebControls.Image 到为System.Drawing.Image ;它甚至不碰的图像数据。

So unfortunately there is no way you can convert a System.Web.UI.WebControls.Image to a System.Drawing.Image; it doesn't even touch the image data.
