我有一个类有这样的代码

pCollection pub = RSSXmlDeserializer.GetPub(path, fReload);

字符串
Get pub是返回pub的集合的方法。
我如何迭代它们。我试过了

for (var n = 0; n < pub.Count; n++) {
}

型
这是getPub方法

public static PCollection GetPub(string path, bool fReload)
    {
        HttpApplicationState session = HttpContext.Current.Application;

        PCollection pub = session["PUB"] as PCollection;

        if pub == null || fReload)
        {
            StreamReader reader = null;

            try
            {
                XmlSerializer serializer = new XmlSerializer(typeof(PCollection));
                reader = new StreamReader(path);
                pub = (PCollection)serializer.Deserialize(reader);
                session["PUB"] = pub;
            }
            catch (Exception ex)
            {
                //throw ex;
            }
            finally
            {
                reader.Close();
            }
        }
        return pub;
    }
}

[Serializable()]
public class Pub
{
    [System.Xml.Serialization.XmlElement("title")]
    public string Title { get; set; }

    [System.Xml.Serialization.XmlElement("description")]
    public string Description { get; set; }

    [System.Xml.Serialization.XmlElement("imageUrl")]
    public string ImageUrl { get; set; }
}

[Serializable()]
[System.Xml.Serialization.XmlRoot("RPublications")]
public class PCollection
{
    [XmlArray("Pub")]
    [XmlArrayItem("Pub", typeof(Pub))]
    public Pub[] Pub { get; set; }
}

型
但是“Count”不被识别。我收到此消息，pCollection没有'Count'的定义...
我如何迭代集合n得到集合元素？
