Making a CURL POST request to server in C# HttpWebRequest

I am attempting to make a POST request to a server. The following works when I CURL using git Bash:
curl -X POST -H "Content-Type: application/octet-stream" -H "User-Agent: MyUserAgent" --data-binary #MyDocument.xlsx http://myUrl.com
I know I can make POST requests using json as follows (in C#):
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(myUrl);
request.Method = "POST";
request.ContentType = "application/json";
request.Accept = "application/json";
request.UserAgent = myUserAgent;
using (var stream = await request.GetRequestStreamAsync())
{
using (StreamWriter streamWriter = new StreamWriter(stream))
{
streamWriter.Write(myJsonData);
}
}
using (HttpWebResponse webResponse = (HttpWebResponse) await request.GetResponseAsync())
{
using (StreamReader reader = new StreamReader(webResponse.GetResponseStream()))
{
string response = reader.ReadToEnd();
//do stuff with response
}
}
My difficulty is basically combining the two. I know I need to change the request.ContentType to "application/octet-stream", but that is not enough. How do I incorporate the "--data-binary #MyDocument.xlsx" in the HttpWebRequest?
Anyone have any ideas? Thanks!

I suggest you look into WebClient since it's easier to implement:
WebClient client = new WebClient();
byte[] response = client.UploadFile(myUrl,fileName);

Method Not Allowed using Cisco REST API

I am trying to change agent state using REST API provided from Cisco.
here is the code that I wrote :
ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri("https://url:8445/finesse/api/User/agent2"));
request.Credentials = new NetworkCredential("agent2", "12345");
request.Method = "POST";
request.ContentType = "application/xml";
// request.Accept = "application/xml";
XElement redmineRequestXML =
new XElement("User",
new XElement("state", "READY"),
new XElement("extension", "3010")
);
byte[] bytes = Encoding.UTF8.GetBytes(redmineRequestXML.ToString());
request.ContentLength = bytes.Length;
using (Stream putStream = request.GetRequestStream())
{
putStream.Write(bytes, 0, bytes.Length);
}
// Log the response from Redmine RESTful service
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
{
MessageBox.Show(reader.ReadToEnd());
}
And I am getting this error :
The remote server returned an error: (405) Method Not Allowed.
so please any idea could help solving this issue ?

after 2 days I figured out that the issue is to replace this line :
request.Method = "POST";
by this line :
request.Method = "PUT";

How to generate curl command using C#

I'm working on Salesforce and wanting to get cases fields in it. found the command
curl https://yoursite.desk.com/api/v2/cases \
-u email:password \
-H 'Accept: application/json'
And I tried it in command prompt as
curl https://xxx.desk.com/api/v2/cases \-u abc#gmail.com:xxxxxxxxx \ -H 'Accept: application/json'
I have tried the below code in C#
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create("https://xxxx.desk.com/api/v2/cases");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Accept = "text/xml";
httpWebRequest.Method = "GET";
httpWebRequest.Credentials = new NetworkCredential("username", "password");
var response = httpWebRequest.GetResponse();
But it is returning an error
The remote server returned an error: (401) Unauthorized.

CURL is just a client for WebRequests
the default C# option is
WebRequest Class
you can also use Restsharp

var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://xxxx.desk.com/api/v2/cases");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Accept = "text/xml";
httpWebRequest.Method = "GET";
httpWebRequest.Credentials = new NetworkCredential("username", "password");
httpWebRequest.Headers.Add("Authorization", "Basic reallylongstring");
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
string text;
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
string fddf = streamReader.ReadToEnd();
}

Getting error while fetching information from windows live server

I am trying to authenticate user through windows live account with following code.
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
WebRequest request = WebRequest.Create("https://oauth.live.com/token");
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = byteArray.Length;
request.Method = "POST";
Stream resp = request.GetRequestStream();
Stream dataStream = request.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
var response = request.GetResponse();
But I am getting following error at last line.
The remote server returned an error: (400) Bad Request.
what should I do for this?

Your issue is probably because we do not send bytes on "application/x-www-form-urlencoded" post but a string. Also the GetRespose is not looks like the correct one. Your code must be something like:
// I do not know how you create the byteArray
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
// but you need to send a string
string strRequest = Encoding.ASCII.GetString(byteArray);
WebRequest request = WebRequest.Create("https://oauth.live.com/token");
request.ContentType = "application/x-www-form-urlencoded";
// not the byte length, but the string
//request.ContentLength = byteArray.Length;
request.ContentLength = strRequest.Length;
request.Method = "POST";
using (StreamWriter streamOut = new StreamWriter(request.GetRequestStream(), System.Text.Encoding.ASCII))
{
streamOut.Write(strRequest);
streamOut.Close();
}
string strResponse;
// get the response
using (StreamReader stIn = new StreamReader(request.GetResponse().GetResponseStream()))
{
strResponse = stIn.ReadToEnd();
stIn.Close();
}
// and here is the results
FullReturnLine = HttpContext.Current.Server.UrlDecode(strResponse);

Getting a 401 error when submitting my datapayload to urbanairship

I'm trying to send a test notification to my ipod via UrbanAirship with C#. I've tried many code snippets trying to send my notification to UrbanAirship from my Windows server, yet I always end up with a 401 error.
Here's my latest code:
string postData = "{\"aps\": {\"badge\": 1, \"alert\": \"Hello from Urban Airship!\"}, \"device_tokens\": [\""+ devToken +"\"]}";
var uri = new Uri("https://go.urbanairship.com/api/push/");
var encoding = new UTF8Encoding();
var request = (HttpWebRequest)WebRequest.Create(uri);
char[] charArray = Encoding.UTF8.GetChars(Encoding.UTF8.GetBytes(postData));
request.Method = "POST";
request.Credentials = new NetworkCredential(username, password);
request.ContentType = "application/json";
request.ContentLength = encoding.GetByteCount(charArray);
using (var stream = request.GetRequestStream())
{
stream.Write(encoding.GetBytes(postData), 0, encoding.GetByteCount(postData));
stream.Close();
var response = request.GetResponse();
response.Close();
}
Note: I've verified that my username and password are correct.
===UPDATE===
I would say that there's something woring with my urbanairship config or so but the following worked:
curl -X PUT -u "appKey:appSecret" -H "Content-Type: application/json" --data '{"alias": "myalias"}' https://go.urbanairship.com/api/device_tokens/myTOken/

Fixed, I've modified my code and most important: YOUR PASSWORD IS THE APPLICATION MASTER SECRET
string postData = "{\"aps\": {\"badge\": 1, \"alert\": \"Hello from Urban Airship!\"}, \"device_tokens\": [\""+ devToken +"\"]}";
var uri = new Uri("https://go.urbanairship.com/api/push/");
var encoding = new UTF8Encoding();
var request = (HttpWebRequest)WebRequest.Create(uri);
char[] charArray = Encoding.UTF8.GetChars(Encoding.UTF8.GetBytes(postData));
request.Method = "POST";
request.Credentials = new NetworkCredential(username, password);
request.ContentType = "application/json";
request.ContentLength = encoding.GetByteCount(charArray);
using (var stream = request.GetRequestStream())
{
stream.Write(encoding.GetBytes(postData), 0, encoding.GetByteCount(postData));
stream.Close();
var response = request.GetResponse();
response.Close();
}
