Deserializing a json string with restsharp

There are sereval ways to do this. A very popular library to handle json is the Newtonsoft.Json. Probably you already have it on your asp.net project but if not, you could add it from nuget.

Considering you have a response object, include the following namespaces and call the static method DeserializeObject<T> from JsonConvert class:

using Newtonsoft.Json;
using RestSharp;

return JsonConvert.DeserializeObject<T>(response.Content);

On the response.Content, you will have the raw result, so just deserialize this string to a json object. The T in the case is the type you need to deserialize.

For example:

var customerDto = JsonConvert.DeserializeObject<CustomerDto>(response.Content);

Update

Recently, Microsoft has added a namespace System.Text.Json which handle json format on the .Net platform. You could use it calling the JsonSerializer.Deserialize<T> static method:

using System.Text.Json;

var customer = JsonSerializer.Deserialize<Customer>(jsonContent);

If you want to avoid using extra libraries, try this:

RestSharp.RestResponse response = new RestSharp.RestResponse();

response.Content = myStringFromDB; 

RestSharp.Deserializers.JsonDeserializer deserial = new JsonDeserializer();

Customer x = deserial.Deserialize<Customer>(response);

Caveats apply - not extensively tested - but seems to work well enough.
