Hi All,

I want to get value from the header.

Means when I pass the parameter from header, I need the value using key from the headers.

Is there any one have idea?

Know the answer? Post it — somebody with the same question will find it here.

Are you looking for specific key?

if (webClient.ResponseHeaders.TryGetValues("yourkey", out values)) { string keyval= values.First(); }

use this for specific key.

Try this:
WebClient webClient = new WebClient();
webClient.QueryString.Add("param1", "value1");
webClient.QueryString.Add("param2", "value2");
string result = webClient.DownloadString("http://theurl.com");

WebHeaderCollection myWebHeaderCollection = webClient.ResponseHeaders;
for (int i=0; i < myWebHeaderCollection.Count; i++)
  Console.WriteLine (myWebHeaderCollection.GetKey(i) + " = " + myWebHeaderCollection.Get(i));

You mean you want to pass header? If so:
If the header already exists:

webClient.Headers.Set("key", "value");

if its a new header:

webClient.Headers.Add("key", "value");
