Sql 如何从 DataTable 中提取数据

我有一个从SQL查询到本地数据库的DataTable，但我不知道如何从中提取数据.

static void Main(string[] args)
{
    const string connectionString = "server=localhost\\SQLExpress;database=master;integrated Security=SSPI;";
    DataTable table = new DataTable("allPrograms");

    using (var conn = new SqlConnection(connectionString))
    {
        Console.WriteLine("connection created successfuly");

        string command = "SELECT * FROM Programs";

        using (var cmd = new SqlCommand(command, conn))
        {
            Console.WriteLine("command created successfuly");

            SqlDataAdapter adapt = new SqlDataAdapter(cmd);

            conn.Open(); 
            Console.WriteLine("connection opened successfuly");
            adapt.Fill(table);
            conn.Close();
            Console.WriteLine("connection closed successfuly");
        }
    }

    Console.Read();
}

我用来在数据库中创建表的命令:

create table programs
(
    progid int primary key identity(1,1),
    name nvarchar(255),
    description nvarchar(500),
    iconFile nvarchar(255),
    installScript nvarchar(255)
)

我怎样才能将数据从DataTable提取到一个有意义的表格中使用？
