Type.GetType(typeName) as a generic type? [duplicate]

I need to build a function to return the deserialized object of a JSON string, the type name is stored in the database:

Type jsonType = Type.GetType(log.JSONClassName);

so I need to do something like this:

var obj = AuditHelper.GetJsonType<jsonType>(log.ObjectJson);

AuditHelper.GetJsonType method:

 public static T GetJsonType<T>(string json)
        {
            var logObject = JsonConvert.DeserializeObject<T>(json);
            return logObject;
        }
