Beispiele

Das folgende Beispiel veranschaulicht die Verwendung von HttpVersion.

// HttpClient lifecycle management best practices:
// https://learn.microsoft.com/dotnet/fundamentals/networking/http/httpclient-guidelines#recommended-use
HttpClient^ client = gcnew HttpClient();

HttpRequestMessage^ request = new HttpRequestMessage(HttpMethod::Get, "http://www.microsoft.com");
Console::WriteLine("Default HTTP request version is {0}", request.Version);

request.Version = HttpVersion.Version10;
Console::WriteLine("Request version after assignment is {0}", request.Version);

HttpResponseMessage^ response = client->Send(request);
Console::WriteLine("Response HTTP version {0}", response.Version);

// HttpClient lifecycle management best practices:
// https://learn.microsoft.com/dotnet/fundamentals/networking/http/httpclient-guidelines#recommended-use
using HttpClient client = new HttpClient();

using HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, "http://www.microsoft.com");
Console.WriteLine("Default HTTP request version is {0}", request.Version);

request.Version = HttpVersion.Version10;
Console.WriteLine("Request version after assignment is {0}", request.Version);

using HttpResponseMessage response = client.Send(request);
Console.WriteLine("Response HTTP version {0}", response.Version);

Using client As New HttpClient()
    Using request As New HttpRequestMessage(HttpMethod.Get, "http://www.microsoft.com")
        Console.WriteLine("Default HTTP request version is {0}", request.Version)

        request.Version = HttpVersion.Version10
        Console.WriteLine("Request version after assignment is {0}", request.Version)

        Using response As HttpResponseMessage = client.Send(request)
