I know there are a lot of questions about sending HTTP POST requests with C#, but I'm looking for a method that uses WebClient rather than HttpWebRequest. Is this possible? It'd be nice because the WebClient class is so easy to use.
I know I can set the Headers property to have certain headers set, but I don't know if it's possible to actually do a POST from WebClient.
You could use Upload method with HTTP 1.0 POST
string postData = Console.ReadLine();
using (System.Net.WebClient wc = new System.Net.WebClient())
{
wc.Headers.Add("Content-Type","application/x-www-form-urlencoded");
// Upload the input string using the HTTP 1.0 POST method.
byte[] byteArray = System.Text.Encoding.ASCII.GetBytes(postData);
byte[] byteResult= wc.UploadData("http://targetwebiste","POST",byteArray);
// Decode and display the result.
Console.WriteLine("\nResult received was {0}",
Encoding.ASCII.GetString(byteResult));
}
