如何从webrequest中删除代理并保持默认webproxy不变

尝试将代理设置为空的WebProxy,即:

request.Proxy = new WebProxy();

这将创建一个空代理。

实际上,将其设置为空将足以禁用自动代理检测,您可能会节省一些周期:)

request.Proxy = null;

        HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(yourRequestUrl);
        if (webRequest.Proxy != null)
        {
            webRequest.Proxy = null;
        }

        webRequest.KeepAlive = true;
        webRequest.Method = "POST";
        webRequest.ContentType = "application/json";
        var json = JsonConvert.SerializeObject(yourObject);
        ASCIIEncoding encoder = new ASCIIEncoding();
        byte[] postBytes = encoder.GetBytes(json);
        webRequest.ContentLength = postBytes.Length;
        webRequest.CookieContainer = new CookieContainer();
        String encoded = System.Convert.ToBase64String(System.Text.Encoding.GetEncoding("ISO-8859-1").GetBytes(string.Format("{0}:{1}", userName, password)));
        webRequest.Headers.Add("Authorization", "Basic " + encoded);
        Stream requestStream = webRequest.GetRequestStream();
        requestStream.Write(postBytes, 0, postBytes.Length);
        requestStream.Close();

        HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse();
        string result;
        using (StreamReader rdr = new StreamReader(response.GetResponseStream()))
        {
                result = rdr.ReadToEnd();
}
