Display system battery status using C# and VB.Net in ASP.Net

Hi mahesh213,

The PowerStatus belongs to System.Windows.Forms namespaces.

So you need to add the reference of System.Windows.Forms in your project.

Then inserit the System.Windows.Forms namespace to use it.

Check this example. Now please take its reference and correct your code.
