You could either use a WebClient as suggested in other answers or fetch the relative path like this:
您可以按照其他答案中的建议使用 WebClient，也可以像这样获取相对路径：
var url = "http://localhost:10001/MyFiles/folder/abc.png";
var uri = new Uri(url);
var path = Path.GetFileName(uri.AbsolutePath);
var file = GetFile(path);
// ...
In general you should get rid of the absolute URLs.
一般来说，您应该摆脱绝对 URL。

Have a look at WebClient(MSDN docs), it has many utility methods for downloading data from the web.
看看WebClient（MSDN 文档），它有许多从网络下载数据的实用方法。
If you want the resource as a Stream, try:
如果您想要资源作为Stream，请尝试：
using(WebClient webClient = new WebClient())
{
using(Stream stream = webClient.OpenRead(uriString))
{
using( StreamReader sr = new StreamReader(stream) )
{
Console.WriteLine(sr.ReadToEnd());
}
}
}

The best way to download the HTML is by using the WebClient class. You do this like:
下载 HTML 的最佳方式是使用 WebClient 类。你这样做：
private string GetWebsiteHtml(string url)
{
WebRequest request = WebRequest.Create(url);
WebResponse response = request.GetResponse();
Stream stream = response.GetResponseStream();
StreamReader reader = new StreamReader(stream);
string result = reader.ReadToEnd();
stream.Dispose();
reader.Dispose();
return result;
}
Then, If you want to further process the HTML to ex. extract images or links, you will want to use technique known as HTML scrapping.
然后，如果你想进一步处理 HTML 到 ex。提取图像或链接，您将需要使用称为 HTML 抓取的技术。
It's currently best achieved by using the HTML Agility Pack.
目前最好通过使用HTML Agility Pack 来实现。
