Adding headers when using httpClient.GetAsync in C#

Adding headers when using httpClient.GetAsync in C#

You can add headers when using HttpClient.GetAsync in C# by creating a new HttpRequestMessage object and setting its Headers property to the desired headers. Then, you can pass this HttpRequestMessage object to the GetAsync method.

Here's an example:

 using (HttpClient httpClient = new HttpClient()) { HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, "http://example.com"); request.Headers.Add("User-Agent", "My User Agent"); request.Headers.Add("X-Custom-Header", "Custom Value"); HttpResponseMessage response = await httpClient.SendAsync(request); // Handle response }

In this example, the User-Agent and X-Custom-Header headers are added to the request by setting the Headers property of the HttpRequestMessage object. The HttpClient then sends the request with these headers using the SendAsync method. Once you have the HttpResponseMessage, you can handle the response as needed.
