need help with returning bool value

Its been a while since I used c# and I am having the hardest time figuring out how to return a bool value. Instead of a copy all and paste I will try to give a short version.

I have 3 classes

program.cs

pingDs.cs

pingRs.cs

inside program.cs I have

public static void main()

{

pingDsDs.pingDs dsPing = new pingDsDs.pingDs();

}

Inside pingDs.cs I have

namespace Pinger

{

class pingDsDb

{

public class pingDs

{

public bool pingable(bool isPingable)

{

bool canPing = isPingable;

return canPing;

}

public void pingDsDb1()

{

inside here I have code to ping my target.

}

I need to return if true or false to Program.cs if the object is pingable. if its not pingable I need to call the other class pingEs which is all the same code except it pings a different target.

What i am trying to do at the end is create a service that pings a system constantly and if it doesnt respond then I need it to ping the other system and change the host file until the preferable host comes up. I have everything else working except returning the success of the ping back to the calling class. I hope I make sense to someone and can get some help on this.
