System Infromation

Question

I am new to C# and trying to rewrite an application. Part of this application reported information about the system e.g. Operating systems HDD size etc. I am able to find out most of this information but cannot determine the HDD Size and Free space or the physical memory of the machine. I would appreciate any help.

In case anyone whats to know how to do this using the information given by spoimala here is the code. //HDD Info System.Management.ManagementObject disk = new System.Management.ManagementObject(Win32_logicaldisk='c:'); System.Management.PropertyDataCollection diskProperties = disk.Properties; System.Management.PropertyData diskProperty = diskProperties[FreeSpace]; long lDiskFree = System.Convert.ToInt64(diskProperty.Value); //Byte System.Management.PropertyData diskProperty2 = diskProperties[Size]; long lDiskSize = System.Convert.ToInt64(diskProperty2.Value); //Byte //Service Pack Number System.Management.ManagementObjectSearcher query2 = new System.Management.ManagementObjectSearcher(SELECT * FROM Win32_OperatingSystem); System.Management.ManagementObjectCollection os = query2.Get(); string spNum =  Service Pack ; foreach (System.Management.ManagementObject mo in os) { spNum += mo[ServicePackMajorVersion].ToString(); } //Memory System.Management.ManagementObjectSearcher query1 = new System.Management.ManagementObjectSearcher(SELECT * FROM Win32_ComputerSystem); System.Management.ManagementObjectCollection cs = query1.Get(); long lRam = 0; foreach (System.Management.ManagementObject mo in cs) { lRam = System.Convert.ToInt64(mo[totalphysicalmemory]); //Bytes }
