ASP.NET - 使用多个不同的参数调用和处理Web API(ASP.NET - Call and handle Web API with multiple different parameters)

 我是Web API的新手，我有一个无法解决的问题。 
 
 这是我的问题：如何调用需要多个参数的Web API（流或对象以及两个或三个字符串）？ 如何处理Web API中的这些参数？ 
 
 例如，我的Web API中有这个方法： 
 
public class MyController : ApiController
{
    [HttpPost]
    public MyObject Method(Stream s, string first, string second)
    {
        // take the parameters and do something
    }
}
 
 其中Stream是文件流（或其他情况下的对象）。 如何将所有这些参数添加到客户端请求正文？ 如何从那里拿出来并在方法中使用？ 
 
 编辑 ：这个解决方案好吗？ 这里的客户： 
 
{
        var client = new HttpClient();
        var queryString = HttpUtility.ParseQueryString(string.Empty);

        queryString["first"] = "true";
        queryString["second"] = "false";
        var uri = "https://myapi.com/api/mycontroller/method?" + queryString;

        HttpResponseMessage response;

        byte[] byteData = Encoding.UTF8.GetBytes(myFile);

        using (var content = new ByteArrayContent(byteData))
        {
           content.Headers.ContentType = new MediaTypeHeaderValue("<application/json >");
           response = await client.PostAsync(uri, content);
        }

    }
 
 这里的Web API： 
 
[HttpPost]
public MyObject Method([FromBody]Stream s, [FromUri]string first, [FromUri]string second)
{
    //do something
}

I am new to Web API and I have question that can not resolve.
 
This is my question: how call a Web API that need multiple parameters (stream or object and two or three string)? And how handle this parameters inside Web API?
 
For example, I have this method in my Web API:
 
public class MyController : ApiController
{
    [HttpPost]
    public MyObject Method(Stream s, string first, string second)
    {
        // take the parameters and do something
    }
}
 
Where Stream is a stream of file (or an object in other cases). How can add all these parameters to client request body? And how take them from there and use in the method?
 
EDIT: this solution is good? Here the client:
 
{
        var client = new HttpClient();
        var queryString = HttpUtility.ParseQueryString(string.Empty);

        queryString["first"] = "true";
        queryString["second"] = "false";
        var uri = "https://myapi.com/api/mycontroller/method?" + queryString;

        HttpResponseMessage response;

        byte[] byteData = Encoding.UTF8.GetBytes(myFile);

        using (var content = new ByteArrayContent(byteData))
        {
           content.Headers.ContentType = new MediaTypeHeaderValue("<application/json >");
           response = await client.PostAsync(uri, content);
        }

    }
 
And here the Web API:
 
[HttpPost]
public MyObject Method([FromBody]Stream s, [FromUri]string first, [FromUri]string second)
{
    //do something
}
