Introduction
This article explains how to get the details of the Monitor connected to your
system. Here I will get the information from the Win32_DesktopMonitor class.
What Win32_DesktopMonitor is
The Win32_DesktopMonitor WMI class represents the type of monitor or display
device attached to the computer system.
Design
Create a new Windows Forms Application Project.
Add one button control to the form.
Design your screen as in the following screen:

Next add a reference for "System.Management".
To add the reference use the following procedure.
Go to Solution Explorer, select the project and right-click on that and choose
"Add Reference" from the menu.

A window will open; in that choose the ".Net" tab.

It will show a list. In that list, choose "System.Management" and click the "OK"
Button.

Now go to the code view.
Add the namespace "using System.Management;".
Write the following code in the Button Click event:
private
void button1_Click(object
sender, EventArgs e)
{
SelectQuery Sq =
new
SelectQuery("Win32_DesktopMonitor");
ManagementObjectSearcher
objOSDetails = new
ManagementObjectSearcher(Sq);
ManagementObjectCollection
osDetailsCollection = objOSDetails.Get();
StringBuilder sb =
new
StringBuilder();
foreach (ManagementObject
mo in osDetailsCollection)
{
sb.AppendLine(string.Format("Name
: {0}", (string)mo["Name"]));
sb.AppendLine(string.Format("Availability:
{0}", (ushort)mo["Availability"]));
sb.AppendLine(string.Format("Caption:
{0}", (string)mo["Caption"]));
sb.AppendLine(string.Format("InstallDate:
{0}", Convert.ToDateTime(mo["InstallDate"]).ToString()));
sb.AppendLine(string.Format("ConfigManagerUserConfig:
{0}", mo["ConfigManagerUserConfig"].ToString()));
sb.AppendLine(string.Format("CreationClassName
: {0}", (string)mo["CreationClassName"]));
sb.AppendLine(string.Format("Description:
{0}", (string)mo["Description"]));
sb.AppendLine(string.Format("DeviceID
: {0}", (string)mo["DeviceID"]));
sb.AppendLine(string.Format("ErrorCleared:
{0}", (string)mo["ErrorCleared"]));
sb.AppendLine(string.Format("ErrorDescription
: {0}", (string)mo["ErrorDescription"]));
sb.AppendLine(string.Format("ConfigManagerUserConfig:
{0}", mo["ConfigManagerUserConfig"].ToString()));
sb.AppendLine(string.Format("LastErrorCode
: {0}", mo["LastErrorCode"]).ToString());
sb.AppendLine(string.Format("MonitorManufacturer
: {0}", mo["MonitorManufacturer"]).ToString());
sb.AppendLine(string.Format("PNPDeviceID:
{0}", (string)mo["PNPDeviceID"]));
sb.AppendLine(string.Format("MonitorType:
{0}", (string)mo["MonitorType"]));
sb.AppendLine(string.Format("PixelsPerXLogicalInch
: {0}", mo["PixelsPerXLogicalInch"].ToString()));
sb.AppendLine(string.Format("PixelsPerYLogicalInch:
{0}", mo["PixelsPerYLogicalInch"].ToString()));
sb.AppendLine(string.Format("ScreenHeight:
{0}", mo["ScreenHeight"].ToString()));
sb.AppendLine(string.Format("ScreenWidth
: {0}", mo["ScreenWidth"]).ToString());
sb.AppendLine(string.Format("Status
: {0}", (string)mo["Status"]));
sb.AppendLine(string.Format("SystemCreationClassName
: {0}", (string)mo["SystemCreationClassName"]));
sb.AppendLine(string.Format("SystemName:
{0}", (string)mo["SystemName"]));
}
MessageBox.Show(sb.ToString());
}
In the code above I am getting the information from Win32_DesktopMonitor and showing it in a Message Box on a button click.
SelectQuery
It represents a WMI Query Language (WQL) SELECT data query.
ManagementObjectSearcher
It retrieves a collection of management objects based on a specified query.
This class is one of the more commonly used entry points to retrieving management information.
ManagementObjectCollection
It represents various collections of management objects retrieved using WMI.
Now build your application. Click on the button; it will show the Battery details in a Message box.
