[2.0] Application Questions

I am going to develop an application in C#.NET 2005 Express Edition, and i want to ask some certain questions and these are as under,

1) How we can get the total size of the C drive and the free space available.

2) How we can get the total size of the RAM and the free space available.

3) How we can determine which operating system is running e.g. NT/XP.

Tell me which method or name space is used to determine all these 3 things.

Thanks

You could achieve all those things using WMI. Try to search about WMI in msdn or in google, surely you could find what you're looking for.

There is an example here. This is also a good site to bookmark if you are going to be doing work in C#.

2) and 3)

VB Code:

System.Management.ManagementClass myManagementClass = new System.Management.ManagementClass("Win32_OperatingSystem");
 
System.Management.ManagementObjectCollection moc = myManagementClass.GetInstances();
 
foreach(System.Management.ManagementObject mo in moc)
{
    MessageBox.Show("Total RAM: " + mo["TotalVisibleMemorySize"].ToString()) + " KB");
    MessageBox.Show("Free RAM: " + (mo["FreePhysicalMemory"].ToString()) + " KB");
    MessageBox.Show("OS: " + mo["Caption"].ToString());
}

Use System.IO.DriveInfo Class

Just another way of doing it would be to add a reference to Microsoft.VisualBasic.dll and use something similar to this

Code:

---

// put "using Microsoft.VisualBasic.Devices"
ComputerInfo myCompInfo = new ComputerInfo();
Console.WriteLine("Physical Memory {0}", myCompInfo.TotalPhysicalMemory );

Use Environment.OSVersion or if you add a reference to Microsoft.VisualBasic.dll then you can also use ComputerInfo.OSFullName property using the above code.
