Send parameters by using GET method in REST server

Question

I have simple REST server GET method:

    public class PersonController : ApiController
    {
        // GET: api/Person
        public IEnumerable<string> Get()
        {
            return new string[] { "value1", "value2" };
        }
...
}

It works fine with cpp rest client:

http_response httpResponse = httpClient.request(methods::GET).get();
    if (httpResponse.status_code() == status_codes::OK)
    {
        wstring output = httpResponse.extract_utf16string().get();
        wcout << output << endl;
    }

I decided to pass some parameters while do GET and have done changes in:

client:

http_response httpResponse = httpClient.request(methods::GET,L"HELLO").get();

server:

public IEnumerable<string> Get([FromBody]string value)

[FromBody]string value I have coppyed from POST method and was expecting it will work.

Unfortunately client call has no response from server side now. Can I use GET with parameters in general? What I do wrong?

UPD:

I have removed [FromBody], but still have response 400 from client side

public IEnumerable<string> Get(string value)
