How to check if dynamic is empty.

Question

I am using Newtonsoft's Json.NET to deserialize a JSON string:

var output = JsonConvert.DeserializeObject("{ 'foo': 'bar' }");

How can I check that output is empty? An example test case:

var output = JsonConvert.DeserializeObject("{ }");
Assert.IsNull(output); // fails

You can just have a string conversion and check if its equal to "{ }".

var output = JsonConvert.DeserializeObject("{ }");

if (output.ToString() =="{ }")
{
    // The object is empty
}
