How to Serialize and DeSerialize a Generic List

private void button1_Click(object sender, EventArgs e)
{
List<Employee> emps = new List<Employee>();
emps.Add(new Employee("1", "Sabu"));
emps.Add(new Employee("2", "John"));
emps.Add(new Employee("3", "Tom"));
emps.Add(new Employee("4", "George"));
string serializedXmlString = XmlSerialize(emps);
List<Employee> deserializedEmps = XmlDeserialize(serializedXmlString);
}

//XmlSerialize method
public string XmlSerialize(List<Employee> emps)
{
System.Xml.Serialization.XmlSerializer xmlSer = new System.Xml.Serialization.XmlSerializer(emps.GetType());
StringWriter textWriter = new StringWriter();
xmlSer.Serialize(textWriter, emps);
xmlSer = null;
return textWriter.ToString();
}


//XmlDeserialize method
public List<Employee> XmlDeserialize(String data)
{
System.Xml.Serialization.XmlSerializer xmlSer = new System.Xml.Serialization.XmlSerializer(typeof(List<Employee>));
TextReader reader = new StringReader(data);
object obj = xmlSer.Deserialize(reader);
return (List<Employee>)obj;
}


//Employee Class with Serializable attribute

[Serializable]
public class Employee
{
public Employee()
{
ID = "";
Name = "";
}

public Employee(String id, String name)
{
ID = id;
Name = name;
}


public string ID { get; set; }
public string Name { get; set; }
}
