如何将 WebResponse. GetResponseStream 返回值转换为字符串？

我看到了很多例子，但是它们都将它们读入字节数组或者256个字符，慢慢地读入。为什么？

将结果 Stream值转换为一个字符串以便我能够解析它，这样做是否明智？

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

You should consider calling WebClient.DownloadString instead.

You can use StreamReader.ReadToEnd(),

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

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();
}
