Range operator creates ParallelQuery<int> containing a sequence of incrementing integers.
This is a static method of the ParallelEnumerable class, rather than an extension method.
public static ParallelQuery<int> Range( int start, int count )
The first parameter is the integer value that the sequence should begin with;
The second is the number of integer that should be in the sequence.
The Range method returns a ParallelQuery<int> that has incrementing values.
The following code shows the use of a parallel range.
We call the static Range method to create a ParallelQuery<int> that contains 10 integers, starting with the value 0.
We then enumerate all the items in the sequence using a foreach loop and print them out.
We use the same range sequence as the basis for a PLINQ query where we select the even integer values and print them out.
using System; using System.Linq; using System.Collections; using System.Collections.Generic; class Program//from w w w.java 2s . c o m { static void Main(string[] args) { ParallelQuery<int> pq = ParallelEnumerable.Range(0, 10); foreach (int i in pq) { Console.WriteLine("Value {0}", i); } IEnumerable<int> results = from i in pq where i % 2 == 0 select i; foreach (int i in results) { Console.WriteLine("Match: {0}", i); } } }
