The safest, general advice would be to always dispose of the HttpResponseMessage once you have finished with using it. This does lead to a little more code noise but ensures that regardless of the internals and any future changes, your code will free/clean up unused resources such as connections as quickly as possible.
A HttpResponseMessage allows us to work with the HTTP protocol (for example, with the headers property) and unifies our return type. In simple words an HttpResponseMessage is a way of returning a message/data from your action.
To get the response body as a string we can use the EntityUtils. toString() method. This method read the content of an HttpEntity object content and return it as a string. The content will be converted using the character set from the entity object.
Several months ago, Microsoft decided to change up the HttpResponseMessage class. Before, you could simply pass a data type into the constructor, and then return the message with that data, but not anymore. Now, you need to use the Content property to set the content of the message.
I think the easiest approach is just to change the last line to
txtBlock.Text = await response.Content.ReadAsStringAsync(); //right!
This way you don't need to introduce any stream readers and you don't need any extension methods.
You need to call GetResponse().
Stream receiveStream = response.GetResponseStream ();
StreamReader readStream = new StreamReader (receiveStream, Encoding.UTF8);
txtBlock.Text = readStream.ReadToEnd();
Try this, you can create an extension method like this:
public static string ContentToString(this HttpContent httpContent)
{
var readAsStringAsync = httpContent.ReadAsStringAsync();
return readAsStringAsync.Result;
}
and then, simple call the extension method:
txtBlock.Text = response.Content.ContentToString();
I hope this help you ;-)
If you want to cast it to specific type (e.g. within tests) you can use ReadAsAsync extension method:
object yourTypeInstance = await response.Content.ReadAsAsync(typeof(YourType));
or following for synchronous code:
object yourTypeInstance = response.Content.ReadAsAsync(typeof(YourType)).Result;
Update: there is also generic option of ReadAsAsync<> which returns specific type instance instead of object-declared one:
YourType yourTypeInstance = await response.Content.ReadAsAsync<YourType>();
By the answer of rudivonstaden
txtBlock.Text = await response.Content.ReadAsStringAsync();
but if you don't want to make the method async you can use
txtBlock.Text = response.Content.ReadAsStringAsync();
txtBlock.Text.Wait();
Wait() it's important, becаuse we are doing async operations and we must wait for the task to complete before going ahead.
