How Can I Get the Total System RAM in C#?

Get the total system memory in C#

In software development, it is often necessary to obtain computer hardware information, especially RAM capacity. In C#, the PerformanceCounter class provides a practical way to obtain available RAM. However, this still leaves a question: how to determine the total amount of RAM on the system?

Use ComputerInfo class

To solve this problem, C# provides the Microsoft.VisualBasic.Devices class in the ComputerInfo namespace. To access this class, you need to add a reference to the Microsoft.VisualBasic assembly and include the corresponding using directive.

Code example:

using Microsoft.VisualBasic.Devices;

// 创建ComputerInfo类的实例
ComputerInfo info = new ComputerInfo();

// 获取以兆字节为单位的总物理内存
long totalMemory = info.TotalPhysicalMemory;

Console.WriteLine("总RAM：{0} MB", totalMemory);

Summary:

By combining the ComputerInfo class and its associated namespace, you can easily retrieve the total physical memory available on your computer. This enhanced insight enables you to effectively tune applications and effectively manage system resources.
