“WebRequest.Create（字符串）”已过时：“WebRequest，请改用 HttpClient。”

我将 .NET 应用程序从版本 NET5 升级到 NET6，并发出警告，指出 WebRequest 类已过时。我在网上查看了一些示例，但是使用 HttpClient 不会像 WebRequest 那样自动获取凭据，因为您需要手动将它们插入到字符串中。

我如何使用 HttpClient 类或类似的类来转换它？

 string url = "website.com";
        WebRequest wr = WebRequest.Create(url);
        wr.Credentials = CredentialCache.DefaultCredentials;
        HttpWebResponse hwr = (HttpWebResponse)wr.GetResponse();
        StreamReader sr = new(hwr.GetResponseStream());
        
    
        sr.Close();
        hwr.Close();

I upgraded my .NET application from the version NET5 to NET6 and placed with a warning that the WebRequest class was obsolete. I've looked at a few examples online, but using HttpClient doesn't automatically grab credentials like WebRequest does, as you need to insert them into a string manually.

How would I convert this using the HttpClient class or similar?

 string url = "website.com";
        WebRequest wr = WebRequest.Create(url);
        wr.Credentials = CredentialCache.DefaultCredentials;
        HttpWebResponse hwr = (HttpWebResponse)wr.GetResponse();
        StreamReader sr = new(hwr.GetResponseStream());
        
    
        sr.Close();
        hwr.Close();

您尝试过以下方法吗？

var myClient = new HttpClient(new HttpClientHandler() { UseDefaultCredentials = true });
var response = await myClient.GetAsync("website.com");
var streamResponse = await response.Content.ReadAsStreamAsync();

Have you tried the following?

var myClient = new HttpClient(new HttpClientHandler() { UseDefaultCredentials = true });
var response = await myClient.GetAsync("website.com");
var streamResponse = await response.Content.ReadAsStreamAsync();
