How to Retrieve Total RAM in C#?

Accessing Total RAM in C#: A Comprehensive Guide

Understanding system hardware, especially RAM capacity, is crucial for many applications. While C# offers the PerformanceCounter class for available RAM, determining total RAM requires a different method. This guide details how to efficiently retrieve total RAM using the Microsoft.VisualBasic assembly.

First, add a reference to the Microsoft.VisualBasic assembly in your C# project. Then, include the necessary namespace:

<code class="language-csharp">using Microsoft.VisualBasic.Devices;</code>

The ComputerInfo class within this assembly provides detailed system hardware information, including total RAM. Here's how to use it:

<code class="language-csharp">// Instantiate ComputerInfo
ComputerInfo computerInfo = new ComputerInfo();

// Retrieve total physical memory (in bytes)
ulong totalPhysicalMemory = computerInfo.TotalPhysicalMemory;</code>

The TotalPhysicalMemory property returns the total installed RAM in bytes. Store this value (in totalPhysicalMemory) for further use in your application.

Remember, the reported value may slightly differ from the manufacturer's specification. This is due to memory reserved by the operating system for internal processes.
