RESTful web service in C# code

Use the WebRequest class. See A REST Client Library for .NET, Part 1.

Please use the below code to invoke a RESTful web service.

string responseMessage; HttpClient client = new HttpClient(serviceUrl); HttpWebRequest request = WebRequest.Create(string.Concat(serviceUrl, resourceUrl)) as HttpWebRequest; request.ContentType = "text/xml"; request.Method = method; HttpContent objContent = HttpContentExtensions.CreateDataContract(requestBody); if(method == "POST" && requestBody != null) { //byte[] requestBodyBytes = ToByteArrayUsingXmlSer(requestBody, "http://schemas.datacontract.org/2004/07/XMLService"); byte[] requestBodyBytes = ToByteArrayUsingDataContractSer(requestBody); request.ContentLength = requestBodyBytes.Length; using (Stream postStream = request.GetRequestStream()) postStream.Write(requestBodyBytes, 0, requestBodyBytes.Length); //request.Timeout = 60000; } HttpWebResponse response = request.GetResponse() as HttpWebResponse; if(response.StatusCode == HttpStatusCode.OK) { Stream responseStream = response.GetResponseStream(); StreamReader reader = new StreamReader(responseStream); responseMessage = reader.ReadToEnd(); } else { responseMessage = response.StatusDescription; } 

The above code needs to refer the following namespaces:

1. using Microsoft.Http; --> Available from the REST Starter Kit (Microsoft.Http.dll)

2. using System.Net;

3. using System.IO;

Look at the OpenRasta project - it is a REST Architecture Solution Targeting Asp.net.
