Create a XML Serialization and Deserialization for generic list in C# windows form application?

I tried code like this.....
//Serialization private void Serialize_Click(object sender, EventArgs e)         {             List<Personal> pdetails = new List<Personal>();             Personal personals = new Personal             {                 ID = int.Parse(txtsno.Text),                 Name = txtname.Text,                 Phone = long.Parse(txtpno.Text),                 Address = txtaddr.Text             };         &nbs ...
