Question

我用这行来反序列化json：

YahooRootObject contacts = new JavaScriptSerializer().Deserialize<YahooRootObject>(stringToParse);

这是YahooRootObject：

public class YahooRootObject
{
    public YahooContacts contacts { get; set; }
}

internal class YahooField
{
    public int id { get; set; }
    public string type { get; set; }
    public object value { get; set; }
    public string editedBy { get; set; }
    public List<object> flags { get; set; }
    public List<object> categories { get; set; }
    public string updated { get; set; }
    public string created { get; set; }
    public string uri { get; set; }
}

internal class YahooContact
{
    public bool isConnection { get; set; }
    public int id { get; set; }
    public List<YahooField> fields { get; set; }
    public List<object> categories { get; set; }
    public int error { get; set; }
    public int restoredId { get; set; }
    public string created { get; set; }
    public string updated { get; set; }
    public string uri { get; set; }
}

internal class YahooContacts
{
    public List<YahooContact> contact { get; set; }
    public int count { get; set; }
    public int start { get; set; }
    public int total { get; set; }
    public string uri { get; set; }
    public bool cache { get; set; }
}

反序列化之后我想使用foreach迭代器，为此我需要在 contacts 对象上实现枚举器。

我的问题是如何在 contacts 对象上实现枚举器以使用foreach迭代器？

只需将IEnumerable<YahooContact>实施添加到YahooContacts类：

internal class YahooContacts : IEnumerable<YahooContact>
{
    public List<YahooContact> contact { get; set; }
    public int count { get; set; }
    public int start { get; set; }
    public int total { get; set; }
    public string uri { get; set; }
    public bool cache { get; set; }

    public IEnumerator<YahooContact> GetEnumerator()
    {
        return contact.GetEnumerator();
    }

    IEnumerator IEnumerable.GetEnumerator()
    {
        return contact.GetEnumerator();
    }
}

在将json反序列化为C＃对象之后如何使foreach迭代器工作？
