Is there an equivalent to "HttpContext.Response.Write" in Asp.Net Core 2?

Submit form using HttpClient in C#

HttpClient.PostAsync return a Task<HttpResponseMessage> so normally it would need to be awaited. As you are using it in main method you would have to get the result from the task

var response = client.PostAsync(uri, formContent).GetAwaiter().GetResult();

Or the simpler

var response = client.PostAsync(uri, formContent).Result;

In both cases response would be an instance of HttpResponseMessage. You can inspect that instance for HTTP status and the content of the response.

If using .net core you can even use an async Main method like

static async Task Main(string[] args) {

    //..code removed for brevity

    var response = await client.PostAsync(uri, formContent);
    var content = await response.Content.ReadAsStringAsync();
    //...
}
