如何以编程方式创建一个DataTable

如何以编程方式创建数据表?我有下面的代码，我想创建一个数据表，就像在Java中，这将允许我创建一个表，我可以从CSV(，)的数据文件，如姓名，地址和电话号码。

代码:

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
      private System.Data.DataSet dataSet;
      System.Data.DataTable table = new DataTable("ParentTable");
        public Form1()
        {
            InitializeComponent();
        }
         private void MakeParentTable()
         {
                    DataColumn column;
                    DataRow row;
                    column = new DataColumn();
                    column.DataType = System.Type.GetType("System.Int32");
                    column.ColumnName = "id";
                    column.ReadOnly = true;
                    column.Unique = true;
                    table.Columns.Add(column);
                    column = new DataColumn();
                    column.DataType = System.Type.GetType("System.String");
                    column.ColumnName = "ParentItem";
                    column.AutoIncrement = false;
                    column.Caption = "ParentItem";
                    column.ReadOnly = false;
                    column.Unique = false;
                    table.Columns.Add(column);
                    DataColumn[] PrimaryKeyColumns = new DataColumn[1];
                    PrimaryKeyColumns[0] = table.Columns["id"];
                    table.PrimaryKey = PrimaryKeyColumns;
                    dataSet = new DataSet();
                    dataSet.Tables.Add(table);
                    for (int i = 0; i<= 2; i++)
                    {
                        row = table.NewRow();
                        row["id"] = i;
                        row["ParentItem"] = "ParentItem " + i;
                        table.Rows.Add(row);
                    }
         }
         private void Form1_Load(object sender, EventArgs e)
         {
             MakeParentTable();
         }
    }
}
