cURL call in C# with flag

The code snippet from http://msdn.microsoft.com/en-us/library/debx8sh9.aspx shows how to send POST data using the WebRequest class:

// Create a request using a URL that can receive a post. WebRequest request = WebRequest.Create("http://localhost:8983/solr/update/extract?literal.id=doc1&commit=true");// Set the Method property of the request to POST.request.Method = "POST";// Create POST data and convert it to a byte array.string postData = "myfile=@tutorial.html";byte[] byteArray = Encoding.UTF8.GetBytes(postData);// Set the ContentType property of the WebRequest.request.ContentType = "application/x-www-form-urlencoded";// Set the ContentLength property of the WebRequest.request.ContentLength = byteArray.Length;

As an alternative to WebRequest, you might consider using the WebClient class. It offers what might be considered to be a cleaner and simpler syntax than WebRequest. Something like this:

using (WebClient client = new WebClient())        {            client.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";            byte[] postResult = client.UploadFile("http://localhost:8983/solr/update/extract?literal.id=doc1&commit=true", "POST", "tutorial.html");        }
