How to get specific value from json string

public class MajorIssue
{
    public int attributeId { get; set; }
    public string attributeKey { get; set; }
    public string attributeValue { get; set; }
}

public class Attributes
{
    public MajorIssue MajorIssue { get; set; }
}

public class RootObject
{
    public string Name { get; set; }
    public string policyName { get; set; }
    public string targetResource { get; set; }
    public Attributes attributes { get; set; }
    public bool enabled { get; set; }
}

dynamic Result = JsonConvert.DeserializeObject<RootObject>(jsonResultFromAPI);

var value = Result.Attributes.MajorIssue.attributeValue;
