How do you do an HTTP Put?

Here’s a C# example using HttpWebRequest:

using System;
using System.IO;
using System.Net;

class Test
{
        static void Main()
        {
                string xml = "<xml>...</xml>";
                byte[] arr = System.Text.Encoding.UTF8.GetBytes(xml);
                HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://localhost/");
                request.Method = "PUT";
                request.ContentType = "text/xml";
                request.ContentLength = arr.Length;
                Stream dataStream = request.GetRequestStream();
                dataStream.Write(arr, 0, arr.Length);
                dataStream.Close();
                HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                string returnString = response.StatusCode.ToString();
                Console.WriteLine(returnString);
        }
}

Update: there’s now an HttpClient class in System.Net.Http (available as a NuGet package) that makes this a bit easier:

using System;
using System.Net.Http;

class Program
{
    static void Main()
    {
        var client = new HttpClient();
        var content = new StringContent("<xml>...</xml>");
        var response = client.PutAsync("http://localhost/", content).Result;
        Console.WriteLine(response.StatusCode);
    }
}
