HowTo: Determine Wireless Strength in .Net

So, have you ever wondered how to get the information about the strength of your wireless signal using .Net?  It is actually pretty easy through .net. 

The .Net framework actually provides the ManagementObjectSearcher object which is part of the System.Management namespace.  This object is a query based object, meaning that if you want to get information out of this object you need to specify the given sql like statement before you can get at the information.  You can use this object to get information on disk drives, network adapters (wireless cards..), CPU usage and more.

Getting the information about the wireless strength is pretty straight forward and can be done in about 5 - 10 lines of code.

Here you go.

Main Method to get the data out of the managment object

Helper method to convert the value to a Int

Let me know if you know of any other/better ways to do this.

How did you know what type of query to use? Is there a site that gives you the fields you may search?

John,

To be honest, I just googled for how to determine wireless status using .net.  Ran across a few different sites that talked about how to do this.

I just spent 10 minutes googling for the list of 'select' statements for the ManagementObjectSearcher and could not find a list that talked about the different possibilities.
