how to implement RestFul web API in asp .net

Hi,
Try this REST web API example.
HTTP GET Requests

static string HttpGet(string url) {
  HttpWebRequest req = WebRequest.Create(url)
                       as HttpWebRequest;
  string result = null;
  using (HttpWebResponse resp = req.GetResponse()
                                as HttpWebResponse)
  {
    StreamReader reader =
        new StreamReader(resp.GetResponseStream());
    result = reader.ReadToEnd();
  }
  return result;
}

HTTP POST Requests

<pre lang="c#">

static string HttpPost(string url,
string[] paramName, string[] paramVal)
{
HttpWebRequest req = WebRequest.Create(new Uri(url))
as HttpWebRequest;
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";

StringBuilder paramz = new StringBuilder();
for (int i = 0; i < paramName.Length; i++) {
paramz.Append(paramName[i]);
paramz.Append("=");
paramz.Append(HttpUtility.UrlEncode(paramVal[i]));
paramz.Append("&");
}

// Encode the parameters as form data:
byte[] formData =
UTF8Encoding.UTF8.GetBytes(paramz.ToString());
req.ContentLength = formData.Length;

// Send the request:
using (Stream post = req.GetRequestStream())
{
post.Write(formData, 0, formData.Length);
}


string result = null;
using (HttpWebResponse resp = req.GetResponse()
as HttpWebResponse)
{
StreamReader reader =
new StreamReader(resp.GetResponseStream());
result = reader.ReadToEnd();
}

return result;
}
