req.Headers.TryAddWithoutValidation("Authorization", "Basic ZWRpdG9yOnhYTXEgM09QNyB4WjlkIHpET3IgOVNhTiB1S3lx==");
//hc.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("attachment; filename = HD - SEIN860.pdf"));

req.Headers.TryAddWithoutValidation("description", "{\"path\":\"/shows/sheriffs-el-dorado-county/2020-2021-season/formats/\",\"title\":\"HD-SEIN860\",\"date\":\"2021-02-08\",\"description\":\"SI1234 / HD-SEIN860 / Airdate 02-10-2021\"}");
req.Content = new StringContent(File.ReadAllText("path"));

var JsonResults = await response.Content.ReadAsStringAsync();

Using CURL to call WebRequest

Good day,
Been trying to call an API using CURL. The CURL is below. How can i pass the {BVN} inside?
curl --location --request GET 'https://api.paystack.co/bank/resolve_bvn/{BVN}' \
--header 'Authorization: Bearer SECRET_KEY'
The conversion of the CURL is as given below but i have issues passing the BVN parameter inside.
using (var httpClient = new HttpClient())
{ using (var request = new HttpRequestMessage(new HttpMethod("GET"),
"https://api.paystack.co/bank/resolve_bvn/{BVN}"))
{
request.Headers.TryAddWithoutValidation("Authorization", "Bearer SECRET_KEY");
var response = await httpClient.SendAsync(request);
}
}

I am not sure where the input is coming from, but you can do
string.format ("https://api.paystack.co/bank/resolve_bvn/{0}", BVN);
and the code for the string BVN will go into {0}

C# Windows Form HttpClient cURL

I need an example of sending a POST request to the server and getting a JSON response.
Problem in sending image.
I have a curl:
curl -k -v -X POST
-H "X-Auth-Token: 123"
-H "Content-Type: image / jpeg"
--data-binary # Face_foto.jpg http: // IP: port / 1 / storage / descriptors? estimate_attributes = 1.
How to implement it in C #

This should work:
HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Add("X-Auth-Token", "123");
using (var stream = File.OpenRead(#"c:\somepath\somefile.jpg"))
{
using (var content = new StreamContent(stream))
{
content.Headers.Add("Content-Type", "image/jpeg");
var result = client.PostAsync("https://www.someuri.com", content).Result;
}
}
I wrote this in a hurry so watch out for issues with PostAsync and the File.OpenRead method.

cURL request in .NET to hide a comment in Facebook page

I read in this answer: facebook api hide comment that you can hide a Facebook comment using this cURL request:
curl -XPOST \
-k \
-F 'is_hidden=true' \
-F 'access_token=[access_token]' \
https://graph.facebook.com/v2.4/[comment_id]
How can I make that request in C#?
Please give a clear working code.

I think the -F flag means it is part of a multipart form: https://ec.haxx.se/http-multipart.html
This may not necessarily work but it should give an idea:
using (var client = new HttpClient())
{
using (var content =
new MultipartFormDataContent("upload----" + DateTime.Now.ToString(CultureInfo.InvariantCulture)))
{
content.Add(new StringContent("true"), "is_hidden");
content.Add(new StringContent("[access_token]"), "access_token");
var response = client.PostAsync(new Uri("https://graph.facebook.com/v2.4/[comment_id]"),
content).Result; // You could use await here
}
}

Connecting to a SOAP WSDL in Visual Studio C#

I am trying to connet my C# console application with a thridparty SOAP WSDL API however I cannot get it working.
I connect to the service with the WSDL string as a Service recourse in Visual studio: https://domain.tld/SimpleAPI/SimpleAPIService.svc?singleWsdl
The documentation says:
Authentication is sessions based. The requester must provide a valid session token in the Authenticate field of each request. A session has access to the same resources and capabilities as the given user. To get a session token, use the GetSessionToken method. To validate a session, use the PingPong method.
The documentation focuses on the REST API, which is not an option for me. The two methods for connecting is as follows:
curl \ -H "Content-Type: application/json" \ -X POST -d '{ "username": "admin#domain.com", "password": "VerySecure123" }' \ https://domain.tld/SimpleAPI/SimpleAPIService.svc/rest/GetSessionToken
This should return something like this: C9C5MlqrpMwG/6bQ3mAVlm0Z6hi/eh1vsQs4i1I/g==
This part is okay, I get a token back. However when I try the PingPong method, I get an error saying that it is a wrong token or the session has expired.
curl \ -H "Content-Type: application/json" \ -H "Authenticate:CCPSessionId C9C5MlqrpMwG/6bQ3mAVlm0Z6hi/eh1vsQs4i1I/g==" \ -X POST -d '{}' \ https://domain.tld/SimpleAPI/SimpleAPIService.svc/rest/PingPong
My code is as follows:
static void Main(string[] args)
{
string apiUsername = "user";
string apiPassword = "pass";
using (var client = new acmp.SimpleAPIServiceClient())
{
client.ClientCredentials.UserName.UserName = apiUsername;
client.ClientCredentials.UserName.Password = apiPassword;
string token = client.GetSessionToken(apiUsername, apiPassword);
string tokenText = string.Format("CCPSessionId {0}", token);
using (OperationContextScope contextScope = new OperationContextScope(client.InnerChannel))
{
var httpRequestProperty = new HttpRequestMessageProperty();
httpRequestProperty.Headers[HttpRequestHeader.Authorization] = token; //tokenText
OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = httpRequestProperty;
client.PingPong();
}
}
Console.WriteLine("End...");
Console.ReadLine();
}
The theory right now is that my script is not passing the correct header.
Please help, we have spend so much time debugging.

Did a little reading up, and I can't find a token text of "CCPSessionsid " anywhere.
I see "bearer", token.AccessToken
Along the lines of:
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("bearer", token.AccessToken);

I also came across this issue while working with the same API. Cutting the quotation marks off the string solved this for me.
request.Headers.TryAddWithoutValidation("Authenticate", token.Trim(new Char[] {'"'}));
