隐式（下方）Web请求的用户代理 [英] User Agent of implicit (underneath) web request
问题描述
我正在使用我没有来源的课程从第三方网络服务器下载文件（它是System.Windows.Media.imaging.Bitmapimage）
Hi, I'm downloading a file from third party web server using a class that I do not have sources (it is System.Windows.Media.imaging.Bitmapimage)
当我以下列方式创建BirmapImage实例时：
When I create instance of BirmapImage the following way:
image = new BitmapImage（ uri ）;
image = new BitmapImage(uri);
下载 uri 指向的二进制文件（png图像）。在下面有一个http请求，指定了一些用户代理。
问题是我下载图像的网站要求其客户使用User-Agent识别自己，而不是提供通用标识。
the binary file (png image) pointed by uri is downloaded. Underneath there is a http request with some user-agent specified.
The problem is that the site from which I download images requires its clients to identify themselves using User-Agent, and not provide generic identification.
我想将自己呈现为例如 "MyApplication V 0.9。 .Net客户端"
I would like to present myself as e.g. "MyApplication V 0.9. .Net client"
是否有可能在没有BitmapImage类源的情况下实现这一点？并且仍然让BitmapImage从网址中为我提取文件？
Is it possible to achieve this without having sources of BitmapImage class ?and still having BitmapImage fetching the file for me from the url ?

推荐答案
创建HttpWebRequest请求 ;并设置UserAgent属性。
Create HttpWebRequest request and set the UserAgent property.
BitmapImage b = new BitmapImage（）;
BitmapImage b = new BitmapImage();
b.StreamSource = request.GetResponse（）。GetResponseStream （）;
b.StreamSource = request.GetResponse().GetResponseStream();
b.BeginInit（）;
b.BeginInit();
b.EndInit（）;
b.EndInit();

我不建议的另一个选择是做一些复杂的事情，比如在配置文件中设置WebRequest模块：
Another option I wouldn't suggest would be to do something complicated like setting a WebRequest module in a config file:
