How to call API from controller with multiple json parameter

I want to call Web API from controller with multiple json parameter. I don't want to use ajax call for get result.

var jsonData = "{\"jsonrpc\":2.0," +
"\"method\":eth_blockNumber," +
"\"params\":[]," +
"\"id\":83}";
HttpWebRequest webreq = (HttpWebRequest)WebRequest.Create(string.Format("https://mainnet.infura.io/qhggowRXK7HIgXB0NEyw",jsonData));
webreq.Method = "POST";
webreq.ContentType = "application/json";
using (var streamWriter = new StreamWriter(webreq.GetRequestStream()))
{
JavaScriptSerializer serializer = new JavaScriptSerializer();
//var resToWrite = serializer.Deserialize>(jsonData);
//streamWriter.Write(jsonData);
streamWriter.Flush();
streamWriter.Close();
}
WebResponse response = webreq.GetResponse();
var streamReader = new StreamReader(response.GetResponseStream());
var result = streamReader.ReadToEnd();

You can simply call API as below:

using (var client = new HttpClient())
{
client.BaseAddress = new Uri("https://mainnet.infura.io/qhggowRXK7HIgXB0NEyw");
client.DefaultRequestHeaders.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var requestBody = new
{
jsonrpc = "2.0",
method = "eth_blockNumber",
@params = new int[]{},
id = 83,
};
HttpResponseMessage apiResponse = await client.PostAsJsonAsync(client.BaseAddress, requestBody);
if (apiResponse.IsSuccessStatusCode)
{
var documentResponse = await apiResponse.Content.ReadAsStringAsync();
dynamic response = JsonConvert.DeserializeObject(documentResponse);
}
}

Need to add nuget package of Http.Formatting.Extension:

Install-Package System.Net.Http.Formatting.Extension

Side note: you'll get response in a dynamic variable, further you can deserialize response in a model, which is not included in this answer.
