Introduction

In this application, user system information has been collected by using two classes:

1. System.Environment
2. System.Managememnt

Using the Code

The main tab in this application has three items:

1. System
2. CPU
3. Local drives

In the System tab, the System.Environment class has been used to gather information:

private string SystemInformation()
{
    StringBuilder StringBuilder1 = new StringBuilder(string.Empty);
    try
    {
        StringBuilder1.AppendFormat("Operation System:  {0}\n", Environment.OSVersion);
        if (Environment.Is64BitOperatingSystem)
            StringBuilder1.AppendFormat("\t\t  64 Bit Operating System\n");
        else
            StringBuilder1.AppendFormat("\t\t  32 Bit Operating System\n");
        StringBuilder1.AppendFormat("SystemDirectory:  {0}\n", Environment.SystemDirectory);
        StringBuilder1.AppendFormat("ProcessorCount:  {0}\n", Environment.ProcessorCount);
        StringBuilder1.AppendFormat("UserDomainName:  {0}\n", Environment.UserDomainName);
        StringBuilder1.AppendFormat("UserName: {0}\n", Environment.UserName);
        //Drives
        StringBuilder1.AppendFormat("LogicalDrives:\n");
        foreach (System.IO.DriveInfo DriveInfo1 in System.IO.DriveInfo.GetDrives())
        {
            try
            {
                StringBuilder1.AppendFormat("\t Drive: {0}\n\t\t VolumeLabel: " + 
                  "{1}\n\t\t DriveType: {2}\n\t\t DriveFormat: {3}\n\t\t " + 
                  "TotalSize: {4}\n\t\t AvailableFreeSpace: {5}\n",
                  DriveInfo1.Name, DriveInfo1.VolumeLabel, DriveInfo1.DriveType, 
                  DriveInfo1.DriveFormat, DriveInfo1.TotalSize, DriveInfo1.AvailableFreeSpace);
            }
            catch
            {
            }
        }
        StringBuilder1.AppendFormat("SystemPageSize:  {0}\n", Environment.SystemPageSize);
        StringBuilder1.AppendFormat("Version:  {0}", Environment.Version);
    }
    catch
    {
    }
    return StringBuilder1.ToString();
}

In the CPU and Local drive tabs, the System.Management class has been used to gather information but before using this class, it has to be added to references. Add System.Management to references:

1. Go to Solution Explorer.
2. Right click on References and select Add Reference.
3. Click on .NET tab.
4. Select System.Management.
5. Select the OK button.

Now we can use this class in the following function:

private string DeviceInformation(string stringIn)
{
    StringBuilder StringBuilder1 = new StringBuilder(string.Empty);
    ManagementClass ManagementClass1 = new ManagementClass(stringIn);
    //Create a ManagementObjectCollection to loop through
    ManagementObjectCollection ManagemenobjCol = ManagementClass1.GetInstances();
    //Get the properties in the class
    PropertyDataCollection properties = ManagementClass1.Properties;
    foreach (ManagementObject obj in ManagemenobjCol)
    {
        foreach (PropertyData property in properties)
        {
            try
            {
                StringBuilder1.AppendLine(property.Name + ":  " + 
                  obj.Properties[property.Name].Value.ToString());
            }
            catch
            {
                //Add codes to manage more informations
            }
        }
        StringBuilder1.AppendLine();
    }
    return StringBuilder1.ToString();
}

Notice that this function has an input string which can be Win32_Processor or Win32_LogicalDisk. We use the first one for collecting information about CPU and the second one for local drives. Now in the Window_Loaded event, we call these functions:

//System Information
textBox1.Text = SystemInformation();
//CPU Information
textBox2.Text = DeviceInformation("Win32_Processor");
//Local Drives Information
textBox3.Text = DeviceInformation("Win32_LogicalDisk");
