C# Environment ProcessorCount

What does the Environment ProcessorCount property do? Although processors can have multiple cores, the ProcessorCount property in the .NET Framework returns the total number of cores on a computer, not processors.

This C# Environment article demonstrates the ProcessorCount property.

Example

This program shows that the dual-core, single processor computer I execute it on returns 2 for ProcessorCount. Conceptually, you can consider these logical, but not physical, processors. The computer actually has only one physical processor.

Program that accesses ProcessorCount [C#]

using System;

class Program
{
    static void Main()
    {
	Console.WriteLine(Environment.ProcessorCount);
    }
}

Output

2

Summary

The ProcessorCount property in the .NET Framework returns the number of logical processors in the executing computer. This means each core is considered a discrete processor, rather than part of a single processor. For this reason, you can use ProcessorCount for creating an array of Threads to use the computer's computational resources fully.
