asp.net C＃转换FILESTREAM图像 [英] asp.net c# convert filestream to image

问题描述

我有我试着去转换成图像文件流。我有以下code

i have a filestream which im trying to convert into a image. i have the following code

FileStream imageFile = image["file"] as FileStream;

图像是图像在地图上保持的信息。请能有人告诉我，我应该下一步该怎么做。

image is a map holding information on the image. please can some one direct me on what I should do next.

推荐答案

Image.FromStream 将采取流，并返回一个图像。顺便说一句，如果你使用 Bitmap.FromStream 或 Image.FromStream ，或任何这些方法，它们都返回位图，所以他们都可以上溯造型到位图从图片如果你想让他们。

Image.FromStream will take a stream and return an image. Incidentally, if you use Bitmap.FromStream or Image.FromStream, or indeed any of these methods, they all return a Bitmap, so they can all be upcast to Bitmap from Image if you want them to be.
