C# download file from the web
Is there a way to make the following function work via proxy?
public T[] ReadStream(System.IO.TextReader reader);
I want to be able to proxify the reader
instance, so开发者_高级运维 that it could download a file from the web on reading attempts and cache it somewhere.
Or maybe there is something default for this purpose?
Use WebClient.DownloadFile. If you need a proxy, you can set the Proxy property of your WebClient object.
Here's an example:
using (var client = new WebClient())
{
client.Proxy = new WebProxy("some.proxy.com", 8000);
client.DownloadFile("example.com/file.jpg", "file.jpg");
}
You can also download the file by parts with a BinaryReader:
using (var client = new WebClient())
{
client.Proxy = new WebProxy("some.proxy.com", 8000);
using (var reader = new BinaryReader(client.OpenRead("example.com/file.jpg")))
{
reader.ReadByte();
reader.ReadInt32();
reader.ReadBoolean();
// etc.
}
}
Perhaps this is what you want? I am also slightly confused by the wording of the question, given your comments to the previous answer.
public StreamReader GetWebReader(string uri)
{
var webRequest = WebRequest.Create(uri);
var webResponse = webRequest.GetResponse();
var responseStream = webResponse.GetResponseStream();
return new StreamReader(responseStream);
}
var webRequestObject = (HttpWebRequest) WebRequest.Create("http://whatever");
var response = webRequestObject.GetResponse();
var webStream = response.GetResponseStream();
// Ta-da.
var reader = new StreamReader(webStream);
