HttpWebRequest 的 HttpWebResponse 的字节数组的字符数组返回“System.Net.HttpWebRequest”

Question

我正在尝试使用 WebRequest.GetResponse(); 请求网页并将该响应转换为字符数组，这样我就可以对数组进行排序并获取页面上的任何 HREF 标记。问题是，在我的代码中的某个地方，响应变成了“System.Net.HttpWebRequest”，而不是应该从页面检索的 HTML。

获取 char 数组的代码：

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(urlTextBox.Text);
            request.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.7 (KHTML, like Gecko) Chrome/7.0.517.44 Safari/534.7";
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
            bytearray = encoding.GetBytes(Convert.ToString(response));
            chararray = encoding.GetChars(bytearray);

搜索链接的代码（注释用于故障排除）：

for (int i = 0; i < chararray.Length; i++)
{
    // Get all HREFs
    if (i < 500 & chararray[i] == 'h' & chararray[i + 1] == 'r' & chararray[i + 2] == 'e' & chararray[i + 3] == '=' & chararray[i + 4] == '"')
    {
        for (int tempi = 0; bytearray[i + 4 + tempi] != '"';)
        {
             tempstring = tempstring + chararray[i + 4 + tempi].ToString();
        }
        urlarray[urlarray.Length + 1] = tempstring;
        i = i + 4;
    }
}
scrapeLink1.Text = urlarray[1];

如果我错过了某些内容，或者需要更多信息，请告诉我。

响应是您必须首先读取的流。

HttpWebRequest request = WebRequest.Create(urlTextBox.Text) as HttpWebRequest;
if (request != null)
{        
    request.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.7 (KHTML, like Gecko) Chrome/7.0.517.44 Safari/534.7";
    using (HttpWebRepsonse response = request.GetResponse() as HttpWebResponse)
    using (StreamReader rdr = new StreamReader(response.GetResponseStream())
    {
        string result = rdr.ReadToEnd();
    }
}
