By Default, Class1.cs is created.in the code window, replace the code with the following: using system; using system.io;
Namespace WebDavnet {///
System.uri myuri = new system.uri (suri); httpWebRequest httpwrequest = (httpwebrequest) WebRequest.create (Myuri);
String squery; squeery = "" "
// Note In Basic type authentication, the username and the password are sent as base64-encoded text, which is // easily decoded. Microsoft recommends that you use Basic over SSL to help protect the username and the password.
// set headers httpwrequest.keepalive = false; httpwrequest.headers.set ("Pragma", "no-cache"); httpwRequest.headers.set ("translate", "f"); httpwrequest.contenttype = "text / xml "HttpwRequest.contentLength = SQuery.Length;
// set the request timeout to 5 min HttpWRequest.Timeout = 300000;. // set the request method HttpWRequest.Method = "PROPPATCH"; // You must store the data in a byte array byte [] ByteQuery = System.Text. Encoding.ASCII.GetBytes (sQuery); HttpWRequest.ContentLength = ByteQuery.Length; Stream QueryStream = HttpWRequest.GetRequestStream (); // Write the data to be posted to the Request Stream QueryStream.Write (ByteQuery, 0, ByteQuery.Length) QueryStream.close ();
// Send Request and Get Response HttpWebResponse HttpWResponse = (HttpWebResponse) HttpWRequest.GetResponse (); // Get the Status code int iStatCode = (int) HttpWResponse.StatusCode; string sStatus = iStatCode.ToString (); Console.WriteLine ( "Status Code: {0} ", sstatus); // Get The Request Headers String Sreqheaders = httpWRequest.Headers.toT7tring (); console.writeline (Sreqheaders);
// Read the Response Stream Stream strm = HttpWResponse.GetResponseStream (); StreamReader sr = new StreamReader (strm); string sText = sr.ReadToEnd (); Console.WriteLine ( "Response: {0}", sText);
// Close stream strm.close ();
// Clean Up myCred = null; myCredentialCache = null; HttpWRequest = null; HttpWResponse = null; QueryStream = null; strm = null; sr = null;} catch (Exception e) {Console.WriteLine ( "{0} Exception caught.
