下列範例會建立 Uri 類別的實例，並使用它搭配 HttpClient 執行 GET 要求。

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

Dim client As New HttpClient()
Dim request As New HttpRequestMessage(HttpMethod.Get, siteUri)
Dim response As HttpResponseMessage = client.Send(request)
