Web API Code to Generate XML from Model and Read XML File into Model

//Write XML based on Customer Model
System.Xml.Serialization.XmlSerializer writer = new System.Xml.Serialization.XmlSerializer(typeof(List<Customer>));
//HardCoded Path, You can create file at application path
var path = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "//Product.xml";
System.IO.FileStream fileObj;

try
{
    fileObj= System.IO.File.Create(path);
    writer.Serialize(fileObj, customerList);
    fileObj.Close();
 }
catch(Exception ex)
{
    throw new ApplicationException("Something went wrong in XML Generation:" + ex.Message);
    //Some logic for error Logging

}

//Read XML in Customer Model
System.Xml.Serialization.XmlSerializer reader = new System.Xml.Serialization.XmlSerializer(typeof(List<Customer>));
System.IO.StreamReader fileReader;
List<Customer> customersList=new List<Customer>();

try
{
    fileReader = new System.IO.StreamReader(path);
    customersList = (List<Customer>)reader.Deserialize(fileReader);
    fileReader.Close();
}
catch (Exception ex)
{
    throw new ApplicationException("Something went wrong in XML Generation:" + ex.Message);
    //Some logic for error Logging
