JToken價值爲String

Question

我從Facebook得到這個JToken回：

JToken userInfo = await CurrentClient.InvokeApiAsync("/.auth/me", HttpMethod.Get, null); 

我需要的姓名和電子郵件出於此。 我試過幾種不同的方法。 有人可以幫忙嗎？

Answer 1

模型，然後使用JToken.ToObject：

var model = userInfo.ToObject<List<Model>>().First(); 
Console.WriteLine("UserID = " + model.UserID);    
Console.WriteLine("Firstname = " + model.UserClaims.First(p => p.ClaimType.Equals("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/givenname")).Value); 
. 
. 
. 
public class Model { 
    [JsonProperty("user_claims")] 
    public List<UserClaim> UserClaims { get; set; } 
    [JsonProperty("user_id")] 
    public string UserID { get; set; } 
} 

public class UserClaim { 
    [JsonProperty("typ")] 
    public string ClaimType { get; set; } 
    [JsonProperty("val")] 
    public string Value { get; set; } 
}
