@happysammy do you have try this solution ?

Hello everybody. I am facing a deserialization problem. Hopefully someone can help me out.
I have to deserialize a list without a container item. It has the following format:

instead of


How can I archive it?

I upgraded to the newest rest sharp version hoping the "Content"-Property of the DeserializeAsAttribute would do the trick, but it did not help.
I think I should mention that it is a list inside of a list. I recently had problems with that too. Can Restsharp handle this?
Adrian Strangfeld
I got it to work using the DotNetSerializer. Is there a way to do it with the other one? (XmlSerializer)
Adrian Strangfeld
I got it to work: The "Content"-Property of the DeserializeAsAttribute did the trick. I did mess it up on my first try.

Hey all, is documentation for older versions of the library available anywhere?

Hello everybody. Is there possible to have logs from RestClient?
Can RestClient be disposed after executing the request?
Maxime Veber
Hello people ! I'm new to restsharp and feeling soooo stupid >_<
Here is my code
And the error is also on the gist.
I don't understand what's wrong !
Maxime Veber
Fixed it, JSON was not what I expected.

Hi everyone :) Can i force RestSharp to use ipv4 instead of ipv6 or do i have to disable ipv6 completely? v6 causes about 20 seconds of delay on the first request :/

Hi all, is it expected that the current locale changes the way the decimal separator is represented in GET requests (and possibly other places)?
E.g.: My system is set to german locale and unless I turn floats to strings myself with the invariant locale when adding them to a request, floats get separated with , in the URL. This confuses the API I want to talk to.

Minimal example:

float a = 1.2f;
var request = new RestRequest("column/longitudinal/diameter_quantity", DataFormat.None)
    .AddParameter("a", ParameterType.QueryString);
var response = restClient.Execute<LongitudinalDiameterAndQuantity>(request, Method.GET);

results in a request to URL /column/longitudinal/diameter_quantity?a=1%2c2

Instead of ., a , is used encoded as %2C

I'm using RestSharp.RestRequest.AddObject to add an arbitrary object to a post request. This mostly does what I need by converting my object into "PropertyName=Value&..." etc. However, I want to use different property names without having to actually use different property names. Something like what Newtonsoft.Json does with the data attribute: [JsonProperty(PropertyName = "myPropertyName")]

Where are the Docs for RestSharp? Does it support Authorization Code Flow with Proof Key for Code Exchange (PKCE)?
Has anyone used RestSharp in a Unity project, building for the UWP for the Hololens 2? I'm getting many 'doesn't exist in target framework' errors because of System DLLs. My target framework is .NET Framework 4.7.1 in Visual Studio.
Solved my problem!

I've used OpenAPI CodeGen to generate a C# client, which appears to be using RestSharp. It's been working fine, but I'm now switching over to HTTPS. I've generated a SSL certificate, installed it on the server, trusted it in my Windows Trusted Root Authority Store and RestSharp is giving me the error: SecureChannelFailure. The exact same endpoint works fine in Chrome, Firefox, Powershell Curl. RestSharp just won't connect.

Probably asked a million times but I cannot find proper documentation. Should I inject my RestSharp client API classes as singleton or transient. I know all about HttpClient to be singeton, but not sure how RestSharp behaves.
Hi guys, i am trying to call a post API with string payload using latest rest sharp version 106.11.7
it is working with the previous version 106.3.1
but in latest version, i am getting bad request. i am updating the library to latest one. please help
MYtype mYtype = new MYtype { Id = "6b2df639-9406-4c67-ba17-7d55b7547c46" };
var request = new RestRequest(Method.POST);
request.RequestFormat = DataFormat.Json;
request.AddHeader("Content-Type", "application/json;");
request.AddHeader("Authorization", $"Bearer {accessToken}");

        var httpClient = new RestClient("service url");
        IRestResponse clientResponse = httpClient.Execute(request);
Service signature :
public async Task<IActionResult> InsertOrUpdateSettings([FromBody]string strSettings)
I am able to hit the service but parameter is null. Same code is working fine with last version
I am working with a project for .NetStandard2.0 and there is an error for RestSharp.
{"Could not load file or assembly 'RestSharp, Version=, Culture=neutral, PublicKeyToken=598062e77f915f75' or one of its dependencies. The system cannot find the file specified.":"RestSharp, Version=, Culture=neutral, PublicKeyToken=598062e77f915f75"}
How can I fix that? I tested with latest version, but I can't fix that.
Hey folks, I am having problem with restsharp on Azure app service. Getting "Unable to connect to remote server" as the error. The same code works locally without any alteration. Does anyone has any idea on how to resolve this?

Hi All, I’ve a requirement to make a call using HTTP Post with MutualTLS authentication.
The call is initiated to the external API endpoint upon a button click from an ASP.Net 4.6.1 MVC App.
I’ve added my application certificate as X509 in the ClientCertificates. In order to perform server certificate validation for mutual TLS , what should be done.
If there are any reference implementation on making this call, or any pointers to achieve mutual TLS, it’ll be highly appreciated. Thank you!
OAuth2Authenticator is obsolete, that means we have to implement IAuthenticator and write the implementation ouself?

Hi! I'm getting the following exception when calling JsonConvert.Serialize(restRequest):
Newtonsoft.Json.JsonSerializationException: Self referencing loop detected for property 'ManifestModule' with type 'System.Reflection.RuntimeModule'. Path 'OnBeforeDeserialization.Method.Module.Assembly'.
Any idea?
I'm using the newest versions of both RestSharp (106.11.7) and Newtonsoft (12.0.3) in .NET 5.
