c# - Problems downloading web pages

Question

In one controller (MVC ASP.NET) I need to download some web pages, and analyze them. Currently I'm using Visual Studio 2019, and .NET Framework 4.8.

My code is like this (simplified):

public async void GetHtmlStream(Uri urlAddr)
{
    HttpClient client = new HttpClient();
    using (HttpResponseMessage Resp = client.GetAsync(urlAddr).Result)
    {
        using (HttpContent content = Resp.Content)
        {
            Stream stream = await content.ReadAsStreamAsync().Result;                
        }
    }
}

The line Stream stream = await content.ReadAsStreamAsync().Result; does not compile: "Error CS1061 'Stream' does not contain definition for 'GetAwaiter' ..."

In a test program, avoiding async and await, i have a line like this: string result = content.ReadAsStringAsync().Result; and all works fine. In the controller, of course nothing works.

I saw a lot of similar issues but I don't understand what should I do to solve the problem.

Answer 1

Try

Stream stream = await content.ReadAsStreamAsync();

instead.
