C#List <>到xml

Question

调用

List<PC> _PCList = new List<PC>();
...add Pc to PCList.. 
WriteXML<List<PC>>(_PCList, "ss.xml");

功能

public static void WriteXML<T>(T o, string filename)
{

    string filePath= Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + "\\Genweb2\\ADSnopper\\" + filename;

    XmlDocument xmlDoc = new XmlDocument();
    XPathNavigator nav = xmlDoc.CreateNavigator();
    using (XmlWriter writer = nav.AppendChild())
    {
        XmlSerializer ser = new XmlSerializer(typeof(List<T>), new XmlRootAttribute("TheRootElementName"));
        ser.Serialize(writer, o); // error
    }
    File.WriteAllText(filePath,xmlDoc.InnerXml);

}

内在的例外

无法转换类型为'System.Collections.Generic.List 1[PC]' to type 'System.Collections.Generic.List1 [System.Collections.Generic.List`1 [PC]]'的对象.

请帮忙

问题在于线路

XmlSerializer ser = new XmlSerializer(typeof(List<T>), ...

你T已经List<PC>,并且你正在尝试创建typeof(List<T>),这将转化为typeof(List<List<PC>>).简单地typeof(T)说吧.
