How to add parameters into a WebRequest?

I need to call a method from a webservice, so I've written this code:

 private string urlPath = "http://xxx.xxx.xxx/manager/";
 string request = urlPath + "index.php/org/get_org_form";
 WebRequest webRequest = WebRequest.Create(request);
 webRequest.Method = "POST";
 webRequest.ContentType = "application/x-www-form-urlencoded";
 webRequest.
 webRequest.ContentLength = 0;
 WebResponse webResponse = webRequest.GetResponse();

But this method requires some parameters, as following:

Post data:

_username:'API USER',         // api authentication username

_password:'API PASSWORD',     // api authentication password

How can I add these parameters into this Webrequest?

Thanks in advance.

Hope this works

webRequest.Credentials= new NetworkCredential("API_User","API_Password");

I have a feeling that the username and password that you are sending should be part of the Authorization Header. So the code below shows you how to create the Base64 string of the username and password. I also included an example of sending the POST data. In my case it was a phone_number parameter.

string credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(_username + ":" + _password));

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(Request);
webRequest.Headers.Add("Authorization", string.Format("Basic {0}", credentials));
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Method = WebRequestMethods.Http.Post;
webRequest.AllowAutoRedirect = true;
webRequest.Proxy = null;

string data = "phone_number=19735559042"; 
byte[] dataStream = Encoding.UTF8.GetBytes(data);

request.ContentLength = dataStream.Length;
Stream newStream = webRequest.GetRequestStream();
newStream.Write(dataStream, 0, dataStream.Length);
newStream.Close();

HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse();
Stream stream = response.GetResponseStream();
StreamReader streamreader = new StreamReader(stream);
string s = streamreader.ReadToEnd();

The code below differs from all other code because at the end it prints the response string in the console that the request returns. I learned in previous posts that the user doesn't get the response Stream and displays it. 

//Visual Basic Implementation Request and Response String
  Dim params = "key1=value1&key2=value2"
    Dim byteArray = UTF8.GetBytes(params)
    Dim url = "https://okay.com"
    Dim client = WebRequest.Create(url)
    client.Method = "POST"
    client.ContentType = "application/x-www-form-urlencoded"
    client.ContentLength = byteArray.Length
    Dim stream = client.GetRequestStream()

    //sending the data
    stream.Write(byteArray, 0, byteArray.Length)
    stream.Close()

//getting the full response in a stream        
Dim response = client.GetResponse().GetResponseStream()

//reading the response 
Dim result = New StreamReader(response)

//Writes response string to Console
    Console.WriteLine(result.ReadToEnd())
    Console.ReadKey()
