例

次の例では、 Uri クラスのインスタンスを作成し、それを使用して HttpClient を使用して GET 要求を実行します。

Uri siteUri = new Uri("http://www.contoso.com/");

// HttpClient lifecycle management best practices:
// https://learn.microsoft.com/dotnet/fundamentals/networking/http/httpclient-guidelines#recommended-use
HttpClient client = new HttpClient();
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, siteUri);
HttpResponseMessage response = client.Send(request);

let siteUri = Uri "http://www.contoso.com/"

// HttpClient lifecycle management best practices:
// https://learn.microsoft.com/dotnet/fundamentals/networking/http/httpclient-guidelines#recommended-use
use client = new HttpClient ()
use request = new HttpRequestMessage (HttpMethod.Get, siteUri)
use response = client.Send request

Dim siteUri As New Uri("http://www.contoso.com/")

' HttpClient lifecycle management best practices:
' https://learn.microsoft.com/dotnet/fundamentals/networking/http/httpclient-guidelines#recommended-use
Dim client As New HttpClient()
Dim request As New HttpRequestMessage(HttpMethod.Get, siteUri)
Dim response As HttpResponseMessage = client.Send(request)
