Note on RestSharp.Signed

The RestSharp package is now signed so there is no need to install RestSharp.Signed, which is obsolete from v160.0.0.

Features

• Assemblies for .NET 4.5.2 and .NET Standard 2.0
• Easy installation using NuGet for most .NET flavors (signed)
• Automatic XML and JSON deserialization
• Supports custom serialization and deserialization via ISerializer and IDeserializer
• Fuzzy element name matching ('product_id' in XML/JSON will match C# property named 'ProductId')
• Automatic detection of type of content returned
• GET, POST, PUT, PATCH, HEAD, OPTIONS, DELETE supported
• Other non-standard HTTP methods also supported
• OAuth 1, OAuth 2, Basic, NTLM and Parameter-based Authenticators included
• Supports custom authentication schemes via IAuthenticator
• Multi-part form/file uploads

var client = new RestClient("http://example.com");
// client.Authenticator = new HttpBasicAuthenticator(username, password);

var request = new RestRequest("resource/{id}", Method.POST);
request.AddParameter("name", "value"); // adds to POST or URL querystring based on Method
request.AddUrlSegment("id", "123"); // replaces matching token in request.Resource

// add parameters for all properties on an object
request.AddObject(object);

// or just whitelisted properties
request.AddObject(object, "PersonId", "Name", ...);

// easily add HTTP Headers
request.AddHeader("header", "value");

// add files to upload (works with compatible verbs)
request.AddFile("file", path);

// execute the request
IRestResponse response = client.Execute(request);
var content = response.Content; // raw content as string

// or automatically deserialize result
// return content type is sniffed but can be explicitly set via RestClient.AddHandler();
IRestResponse<Person> response2 = client.Execute<Person>(request);
var name = response2.Data.Name;

// or download and save file to disk
client.DownloadData(request).SaveAs(path);

// easy async support
await client.ExecuteAsync(request);

// async with deserialization
var asyncHandle = client.ExecuteAsync<Person>(request, response => {
    Console.WriteLine(response.Data.Name);
});

// abort the request on demand
asyncHandle.Abort();
