How to convert WebResponse.GetResponseStream return into a string?

问题

I see many examples but all of them read them into byte arrays or 256 chars at a time, slowly. Why?

Is it not advisable to just convert the resulting Stream value into a string where I can parse it?

回答1:

You should create a StreamReader around the stream, then call ReadToEnd.

You should consider calling WebClient.DownloadString instead.

回答2:

You can use StreamReader.ReadToEnd(),

using (Stream stream = response.GetResponseStream())
{
   StreamReader reader = new StreamReader(stream, Encoding.UTF8);
   String responseString = reader.ReadToEnd();
}

回答3:

As @Heinzi mentioned the character set of the response should be used.

var encoding = response.CharacterSet == ""
    ? Encoding.UTF8
    : Encoding.GetEncoding(response.CharacterSet);

using (var stream = response.GetResponseStream())
{
    var reader = new StreamReader(stream, encoding);
    var responseString = reader.ReadToEnd();
}

Richard Schneider is right. use code below to fetch data from site which is not utf8 charset will get wrong string.

using (Stream stream = response.GetResponseStream())
{
   StreamReader reader = new StreamReader(stream, Encoding.UTF8);
   String responseString = reader.ReadToEnd();
}

You can create a StreamReader around the stream, then call StreamReader.ReadToEnd().

StreamReader responseReader = new StreamReader(request.GetResponse().GetResponseStream());
var responseData = responseReader.ReadToEnd();
