Examples

// HttpClient is intended to be instantiated once per application, rather than per-use. See Remarks.
static readonly HttpClient client = new HttpClient();

static async Task Main()
{
 // Call asynchronous network methods in a try/catch block to handle exceptions.
 try
 {
 using HttpResponseMessage response = await client.GetAsync("http://www.contoso.com/");
 response.EnsureSuccessStatusCode();
 string responseBody = await response.Content.ReadAsStringAsync();
 // Above three lines can be replaced with new helper method below
 // string responseBody = await client.GetStringAsync(uri);

 Console.WriteLine(responseBody);
 }
 catch (HttpRequestException e)
 {
 Console.WriteLine("\nException Caught!");
 Console.WriteLine("Message :{0} ", e.Message);
 }
}

open System.Net.Http

// HttpClient is intended to be instantiated once per application, rather than per-use. See Remarks.
let client = new HttpClient()

let main =
 task {
 // Call asynchronous network methods in a try/catch block to handle exceptions.
 try
 use! response = client.GetAsync "http://www.contoso.com/"
 response.EnsureSuccessStatusCode() |> ignore
 let! responseBody = response.Content.ReadAsStringAsync()
 // Above three lines can be replaced with new helper method below
 // let! responseBody = client.GetStringAsync uri

 printfn $"{responseBody}"
 with
 | :? HttpRequestException as e ->
 printfn "\nException Caught!"
 printfn $"Message :{e.Message} "
 }

main.Wait()

' HttpClient is intended to be instantiated once per application, rather than per-use. See Remarks.
Shared ReadOnly client As HttpClient = New HttpClient()

Private Shared Async Function Main() As Task
 ' Call asynchronous network methods in a try/catch block to handle exceptions.
 Try
 Using response As HttpResponseMessage = Await client.GetAsync("http://www.contoso.com/")
 response.EnsureSuccessStatusCode()
 Dim responseBody As String = Await response.Content.ReadAsStringAsync()
 ' Above three lines can be replaced with new helper method below
 ' Dim responseBody As String = Await client.GetStringAsync(uri)

 Console.WriteLine(responseBody)
 End Using
 Catch e As HttpRequestException
 Console.WriteLine(Environment.NewLine & "Exception Caught!")
 Console.WriteLine("Message :{0} ", e.Message)
 End Try
End Function

The preceding code example uses an async Task Main() entry point. That feature requires C# 7.1 or later.

Remarks

A common way to get an HttpResponseMessage is from one of the HttpClient.SendAsync(HttpRequestMessage) methods.
