How to read HttpResponseMessage content as text

You can use ReadAsStringAsync on the Content.

var response = await client.SendAsync(request);
var content = await response.Content.ReadAsStringAsync();

Note that you usually should be using await - not .Result.

The textual representation of the response is hidden in the Content property of the HttpResponseMessage class. Specifically, you get the response like this:

response.Content.ReadAsStringAsync();

Like all modern Async methods, ReadAsStringAsync returns a Task. To get the result directly, use the Result property of the task:

response.Content.ReadAsStringAsync().Result;

Note that Result is blocking. You can also await ReadAsStringAsync().
