问题描述

先生！

i有xml序列化的代码，但它产生无效的操作异常。

代码如下：

sir !
i have code for xml serialization but it producing invalid operation exception.
The code is below:

public class employee
    {
        public string name;
    }
    public class company
    {
        [XmlAttribute]
        public string comapnyname;
        [XmlAttribute]
        public XmlAttribute[] xattributes;
        [XmlAnyElement]
        public XmlElement[] xelements;
        [XmlElement(ElementName = "Members")]
        public employee[] employee;

        public void serializexml()
        {
            string filename = "D:\\xmlserialization.xml";
            XmlSerializer xmlserial = new XmlSerializer(typeof(company));
            TextWriter textwrite = new StreamWriter(filename);
            company com = new company();
            com.comapnyname = "hello world ltd";
            employee emp = new employee();
            employee emp1 = new employee();
            emp.name = "tushar";
            emp1.name = "mayank";
            com.employee = new employee[2]
            {
                emp,emp1};
            xmlserial.Serialize(textwrite, com);
            textwrite.Close();
            FileStream fs = new FileStream(filename, FileMode.Open);
            company cmp = (company)xmlserial.Deserialize(fs);
            Console.WriteLine(cmp.comapnyname);
            foreach (employee e in cmp.employee)
            {
                Console.WriteLine("{0}", e.name);
            }
        }
        public static void Main(String[] ar)
        {
            company co = new company();
            co.serializexml();
            Console.ReadLine();
        }
    }
}
