LINQ入门语法
Code
class IntroToLINQ
{
static void Main()
{
// The Three Parts of a LINQ Query:
// 1. Data source.
int[] numbers = new int[7] { 0, 1, 2, 3, 4, 5, 6 };
// 2. Query creation.
// numQuery is an IEnumerable<int>
var numQuery =
from num in numbers
where (num % 2) == 0
select num;
// 3. Query execution.
foreach (int num in numQuery)
{
Console.Write("{0,1} ", num);
}
}
}
将查询出来的数据添加到一个集合
static void Main(string[] args)
{ // The Three Parts of a LINQ Query:
// 1. Data source.
int[] numbers = new int[7] { 0, 1, 2, 3, 4, 5, 6 };
List<int> numQuery2 = (from num in numbers where (num % 2) == 0 select num).ToList();
foreach (int num in numQuery2)
{
Console.WriteLine("{0,1}", num);
}
Console.ReadLine();
