c#后代码

复制代码 代码如下:

DataTable Commodity = newTable();

        public MainWindow()
        {
            InitializeComponent();
            //DataTable Commodity = newTable();

        }

      

        private void btnAdd_Click(object sender, RoutedEventArgs e)
        {

            addNewMember(Commodity);
            lstDisplay.DataContext = Commodity;

        }

        private void btnDelete_Click(object sender, RoutedEventArgs e)
        {
            Button b = sender as Button;
            Int32 AutoID = Convert.ToInt32(b.CommandParameter);
            delMember(Commodity, AutoID);
            lstDisplay.DataContext = Commodity;
            lstDisplay.Items.Refresh();

        }

        private DataTable delMember(DataTable Table,Int32 laction)
        {
            //Deleting  a existed row in datatable Commodity;
            DataRow delRow = Table.Rows.Find(laction);
            Table.Rows.Remove(delRow);
            return Table;
        }

        private  DataTable addNewMember(DataTable Table)
        {
           

            //inserting a new row in datatable Commodity;

            DataRow newRow = Table.NewRow();
            newRow["ComName"] = tbkName.Text;
            newRow["ComInPrice"] = tbkInPrice.Text;
            newRow["ComOutPrice"] = tbkOutPrice.Text;
            newRow["ComCount"] = tbkComCount.Text;
            Table.Rows.Add(newRow);
            return Table;
        }

 

        private static DataTable newTable()
        {
            //Create a new table named Commodity
            DataTable commodity = new DataTable("Commodity");

            //instert new columns
            DataColumn auto = new DataColumn("AutoID", typeof(Int32));
            //setting the column auto increment
            auto.AutoIncrement = true;
            commodity.Columns.Add(auto);
            commodity.Columns.Add("ComName", typeof(string));
            commodity.Columns.Add("ComInPrice", typeof(double));
            commodity.Columns.Add("ComOutPrice", typeof(double));
            commodity.Columns.Add("ComCount", typeof(System.Int32));
