[FIXED] How to extract integer values from inside a string

Issue

I run the PowerShell command to get total RAM capacity using C# and it returns this value. @{TotalPhysicalMemory= 17856325}. I wrote a code to get the only integer value. This is the code.

string ramSize = "@{TotalPhysicalMemory= 17856325}";
string ramValue = ramSize.Split('=')[1].Split('}')[0].Trim().ToString();

This code returns the integer value. But I want to know are there any ways to get this integer value easily?

Solution

a simple regex to extract the digits in the string will do it.

var ram = new Regex(@"\d+").Match(ramSize).Value;

you can also add System.Management and directly get the size by

            var ram =
            new ManagementObjectSearcher("root\\CIMV2",
                    "SELECT TotalPhysicalMemory FROM Win32_ComputerSystem")
                .Get().OfType<ManagementObject>().First()
                .Properties.OfType<PropertyData>().First().Value;
