C# – How do you get total amount of RAM the computer has?

The following would retrieve how much ram is available:

PerformanceCounter ramCounter;
ramCounter = new PerformanceCounter("Memory", "Available MBytes");
Console.WriteLine("Total RAM: " + ramCounter.NextValue().ToString() + " MB\n\n");

Of course we will have to use the System.Diagnostics; class.

Does performancecounter have any functionality for retrieving the amount of RAM of a particular machine? I’m not talking about the amount of ram used or unused. I’m talking about the amount of ram the machine has.

Answer 1

This information is already available directly in the .NET framework, you might as well use it. Project + Add Reference, select Microsoft.VisualBasic.

using System;

class Program {
    static void Main(string[] args) {
        Console.WriteLine("You have {0} bytes of RAM",
            new Microsoft.VisualBasic.Devices.ComputerInfo().TotalPhysicalMemory);
        Console.ReadLine();
    }
}

And no, it doesn’t turn your C# code into vb.net.
