它不是纯粹的 LINQ,但它打算与它一起使用:
public static class MyEnumerableExtensions
{
public static IEnumerable<T[]> Split<T>(this IEnumerable<T> source, int size)
{
if (source == null)
{
throw new ArgumentNullException("source can't be null.");
}
if (size == 0)
{
throw new ArgumentOutOfRangeException("Chunk size can't be 0.");
}
List<T> result = new List<T>(size);
foreach (T x in source)
{
result.Add(x);
if (result.Count == size)
{
yield return result.ToArray();
result = new List<T>(size);
}
}
}
}
它可以从您的代码中用作:
private void Test()
{
// Here's your original sequence
IEnumerable<int> seq = new[] { 1, 2, 3, 4, 5, 6 };
// Here's the result of splitting into chunks of some length
// (here's the chunks length equals 3).
// You can manipulate with this sequence further,
// like filtering or joining e.t.c.
var splitted = seq.Split(3);
}
