如何在LINQ(到数据集)中计算DataTable列的总和？

using System;
using System.Data;
using System.Linq;

class Program
{
    static void Main(string[] args)
    {
        DataTable table = new DataTable();
        table.Columns.Add("Value", typeof(int));

        table.Rows.Add(1);
        table.Rows.Add(2);
        table.Rows.Add(3);

        int sum = table.AsEnumerable().Sum(row => row.Field<int>("Value"));

        Console.WriteLine("The sum of the DataTable column is: " + sum);
    }
}
