How to Get Total Physical RAM in C#

You can easily access the system's total physical memory (RAM) programmatically using C# by adding a reference to Microsoft.VisualBasic in your project.

Next, retrieve the total physical RAM of your system in bytes.

ulong ram = (new Microsoft.VisualBasic.Devices.ComputerInfo().TotalPhysicalMemory) / (1024 * 1024);

You should convert the value as follows:

• To get Kilobytes, divide by 1024;
• To get Megabytes, divide by 1024 * 1024;
• To get Gigabytes, divide by 1024 * 1024 * 1024, and so on.
