Serialization of DataGridView

//Create a user control name "ucMarketWatch" in the project and put a grid in the control

//Firstly create a class name "Serializer.cs" in the project


using System;

using System.Text;
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;
