How to send xml through an HTTP request, and receive it using ASP.NET MVC?

Question

I am trying to send an xml string through an HTTP request, and receive it on the other end. On the receiving end, I am always getting that the xml is null. Can you tell me why that is? Send: ``` var url = "http://website.com"; var postData = "..."; byte[] bytes = System.Text.Encoding.ASCII.GetBytes(postData); var req = (HttpWebRequest)WebRequest.Create(url); req.ContentType = "text/xml"; req.Method = "POST"; req.ContentLength = bytes.Length; using (Stream os = req.GetRequestStream()) { os.Write(bytes, 0, bytes.Length); } string response = ""; using (System.Net.WebResponse resp = req.GetResponse()) { using (StreamReader sr = new StreamReader(resp.GetResponseStream())) { response = sr.ReadToEnd().Trim(); } } ``` Receive: ``` [HttpPost] [ValidateInput(false)] public ActionResult Index(string xml) { //xml is always null ... return View(model); } ```

Accepted Answer

I was able to get this working like so:

```
[HttpPost]
[ValidateInput(false)]
public ActionResult Index()
{
    string xml = "";
    if(Request.InputStream != null){
        StreamReader stream = new StreamReader(Request.InputStream);
        string x = stream.ReadToEnd();
        xml = HttpUtility.UrlDecode(x);
    }
    ...
    return View(model);
}
```

However, I am still curious why taking the xml as a parameter does not work.
