How to covert HttpWebRequest implementation to HttpClient

I have one service method which is using HttpWebRequest for below stuff

while (ub < sentCount)
{
ub = step * (1 + (i++));
var k = (ub > sentCount) ? (sentCount) : ub; //to avoid array out of range exception(assign unitll array length if calc exceeds)
for (int j = lb; j < k; j++)
{
pnos = pnos + "," + pnosList[j].Phone;
}
pnos = pnos.Substring(1);
var sbPostData = new StringBuilder();
sbPostData.AppendFormat("authkey={0}", api.AuthenticationKey);
sbPostData.AppendFormat("&mobiles={0}", pnos);
sbPostData.AppendFormat("&message={0}", message);
sbPostData.AppendFormat("&sender={0}", api.SenderId);
sbPostData.AppendFormat("&route={0}", "default");
string sendSMSUri = api.EndPoint;
// Create HTTPWebrequest
var httpWReq = (HttpWebRequest)WebRequest.Create(sendSMSUri);
//Prepare and Add URL Encoded data
var encoding = new UTF8Encoding();
byte[] data = encoding.GetBytes(sbPostData.ToString());
//Specify post method
httpWReq.Method = "POST";
httpWReq.ContentType = "application/x-www-form-urlencoded";
//httpWReq.ContentLength = data.Length;
using (Stream stream = httpWReq.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
//Get the response
var response = (HttpWebResponse)httpWReq.GetResponse();
var reader = new StreamReader(response.GetResponseStream());
string responseString = reader.ReadToEnd();
//Close the response
reader.Close();
response.Close();
lb = ub;
pnos = string.Empty;
}

Now the same thing I need to do in HttpClient is it possible to do that. Issue I am facing is HttpWebRequest is not supporting in PCL(C# class library) I want to move above logic to PCL.

Please replace with your post data "values"

please replace your with your api endpoint "url"

incase of any issues pls revert back

var values = new Dictionary
{
{"token", token},
{"forStorage", "true"},
{"MaxBatchSize", "1000"},
{"outFields", "*"},
{"f", "json"},
{"addresses", inputJson} //inputJson is an array of a complex type
};

using (var client = new HttpClient())
{
try
{
var content = new FormUrlEncodedContent(values);
var response = await client.PostAsync(url, content);
Task responseString = response.Content.ReadAsStringAsync();
string outputJson = await responseString;
res = JsonConvert.DeserializeObject(outputJson);
}
catch (Exception ex)
{
Debug.WriteLine(ex.ToString()); //"Invalid URI: The Uri string is too long."
}
}

using (var client = new HttpClient())
{
try
{
var content = new FormUrlEncodedContent(values);
var response = await client.PostAsync(url, content);
Task responseString = response.Content.ReadAsStringAsync();
string outputJson = await responseString;
res = JsonConvert.DeserializeObject(outputJson);
}
catch (Exception ex)
{
Debug.WriteLine(ex.ToString()); //"Invalid URI: The Uri string is too long."
}
}
