Getters and Setters not saving variable to output - getter

Question

Ive been trying for hours to fix this code I just can't seem to understand the problem, I'm storing a variable with get and set inside of a public containing a case. What I'm trying to do is use this menu below to store the variable.
{
Volume vol = new Volume();
Console.WriteLine("\n ---------------\n" +
" |>>>>> Control Panel <<<<<|\n" +
" ---------------" +
"\n\n |===========================================|\n" +
"\n Press key...\n" +
"\n [Q] to Change M Main 1 Volume\n" +
" [W] to Change M Main 2 Volume\n" +
" [E] to Change Host Volume\n" +
" [R] to Change Guest Volume\n" +
" [T] to Change Speaker Volume\n" +
" [Y] to Change Lights\n" +
" [G] to exit\n" +
"\n |===========================================|");
ConsoleKeyInfo inputuser = Console.ReadKey(true);
switch (inputuser.Key)
{
case ConsoleKey.Q:
{
try
{
Console.WriteLine("| | |Input Volume percentege from 0-100 %| | |");
vol.MainMic1 = int.Parse(Console.ReadLine());
if (vol.MainMic1 > 100 || vol.MainMic1 < 0)
{
Console.WriteLine("Invalid Number");
Console.ReadKey();
}
else if (vol.MainMic1 == 0 || vol.MainMic1 <= 100)
Console.WriteLine(vol.MainMic1);
Console.ReadKey(); ```
This sets it in this current method because I tried it but not in the method I use to call it, when I call it in console it returns its original value or 0
public void ShowVolume()
{
Volume voll = new Volume();
Console.Clear();
Console.WriteLine("|====== ====== ====== ====== ====== ====== ======|\n" +
"\n >>>>> Lights and Volume settings <<<<<\n" +
"\nMain 1(Peterson) Microphone currently at: {0}% volume.\n" +
"Co-Speaker(Weiss) Microphone currently at: {1}% volume.\n" +
"Host Microphone currently at: {2}% volume.\n" +
"Guest Microphone currently at: {3}% volume.\n" +
"Quad-Speakers currently at: {4}% volume.\n" +
"Lights are at: {5}% power.\n" +
"\n|====== ====== ====== ====== ====== ====== ======|", voll.MainMic1, voll.MainMic2, voll.MainMic3, voll.GuestMic, voll.QuadSpeaker, voll.Lighting);
Console.ReadKey();
I can't figure out the problem, I get everything to run, but not to print what is asked, is there some sort of case /method blockage here I don't understand?
here is class with get/set
public class Volume
{
private int o_mainmic1 = 50;
private int o_mainmic2 = 50;
private int o_mainmic3 = 50;
private int o_guestmic = 30;
private int o_quadspeaker = 30;
private int o_lighting = 30;
public int MainMic1
{
get
{
return o_mainmic1;
}
set
{
o_mainmic1 = value;
}
}
Here are some Gyazo pictures if that is of help to you, I appreaciate any assistance I get here, thanks in advance.

Answer 1

Step 1:
Make Volume static:
public static class Volume
{
private int o_mainmic1 = 50;
private int o_mainmic2 = 50;
private int o_mainmic3 = 50;
private int o_guestmic = 30;
private int o_quadspeaker = 30;
private int o_lighting = 30;
public int MainMic1
{
get
{
return o_mainmic1;
}
set
{
o_mainmic1 = value;
}
}
Step 2: Rename every mention of vol or voll to Volume and don't initialize the Volume class.
[first code sample]
{
Volume vol = new Volume(); // Delete this, this is not needed anymore since Volume is a static class.
/* I skipped over the Console.WriteLine stuff, though you need it.
*/
ConsoleKeyInfo inputuser = Console.ReadKey(true);
switch (inputuser.Key)
{
case ConsoleKey.Q:
{
try
{
Console.WriteLine("| | |Input Volume percentege from 0-100 %| | |");
Volume.MainMic1 = int.Parse(Console.ReadLine());
if (Volume.MainMic1 > 100 || Volume.MainMic1 < 0)
{
Console.WriteLine("Invalid Number");
Console.ReadKey();
}
else if (Volume.MainMic1 == 0 || Volume.MainMic1 <= 100)
{
Console.WriteLine(vol.MainMic1);
Console.ReadKey();
}
[second code sample]
public void ShowVolume()
{
Volume voll = new Volume(); //Again, delete this.
Console.Clear();
Console.WriteLine("|====== ====== ====== ====== ====== ====== ======|\n" +
"\n >>>>> Lights and Volume settings <<<<<\n" +
"\nMain 1(Peterson) Microphone currently at: {0}% volume.\n" +
"Co-Speaker(Weiss) Microphone currently at: {1}% volume.\n" +
"Host Microphone currently at: {2}% volume.\n" +
"Guest Microphone currently at: {3}% volume.\n" +
"Quad-Speakers currently at: {4}% volume.\n" +
"Lights are at: {5}% power.\n" +
"\n|====== ====== ====== ====== ====== ====== ======|", Volume.MainMic1, Volume.MainMic2, Volume.MainMic3, Volume.GuestMic, Volume.QuadSpeaker, Volume.Lighting);
Console.ReadKey();
