Csharp method does not save or return any value eventhough

Question

Hello! How are you doing dear all?   I am trying to do some training in Csharp, typing a small console program to calculate vaules from seperated classes and methods, I have typed like these lines so far: using  System;   namespace  spacesqm   {   public   class  EnterData   {   public   int  length;   public   int  width;   public   int  height;   public   int  EnterNumbers ()   {   Console.WriteLine ( "Welcome, Can you press any Key to proceed!" );   Console.ReadKey ();   //Type and record the 'length' Variable    Console.WriteLine ( "Type The Length in centimeter: " );   length = Convert.ToInt32 (Console.ReadLine());      Console.WriteLine ( "Type The width in centimeter: " );   width = Convert.ToInt32 (Console.ReadLine());      Console.WriteLine ( "Type The height in centimeter: " );   height = Convert.ToInt32 (Console.ReadLine());      //Type Thank you and close the method    Console.WriteLine ( "Thank you a lot the information had been entered successfully!" );   Console.WriteLine ( "Type any key to Calculate..." );   Console.ReadKey ();   Console.Clear ();   return  (length, width, height) ;   }   }   }   The problem is that, when I call the values from another class, the value return 0 eventhough...   Do you have any solution pls?   Thank you & Regards, Ehssan Dannouf,

Hi again!    This time it works really, but I still could not find the reason how the old type did not work, can you determin what was the problem though?      Main class was just like:    using  System;      namespace  manipulateTwoVariablesApp   {   class  MainClass   {   public   static   int  Number1;    public   static   int  Number2;    public   static   int  calculateNumbers;    public   static   void  Main ( string [] args)   {   Console.WriteLine ( "Type First Number pls:" );    Number1 = Convert.ToInt32(Console.ReadLine());    Console.WriteLine ( "Type Second Number pls:" );    Number2 = Convert.ToInt32(Console.ReadLine ());    calculateNumbers = Number1 + Number2;    Console.WriteLine ( "To calculate, Number 1 + Number 2 is like: "  + calculateNumbers );    //manipulateTwoVariablesApp.recordVariablesClass.recordVariablesClassNumbers ();     manipulateTwoVariablesApp.PressAnyKeyClass.PressAnyKeyClasstoMoveOne ();    int  showNum1 = Number1;   int  showNum2 = Number2;    Console.WriteLine ( "You have enetered so far: Number1, Number2 Variables as like:"  +   "
" );    Console.WriteLine (showNum1);   Console.WriteLine (showNum2);   manipulateTwoVariablesApp.CheckNumAgain.CheckNumAgainAndPrint ();    Console.WriteLine ( "I have told you dude, Your Numbers have been calculated as like:"  +   "
"  + CheckNumAgain.calculateNumbers);   }   }   }   Secondary class was just like:  using  System;      namespace  manipulateTwoVariablesApp   {   public   class  CheckNumAgain   {   public   static   int  Number1;    public   static   int  Number2;    public   static   int  calculateNumbers;       public   static   int  CheckNumAgainAndPrint ()   {   Console.WriteLine ( "Type First Number pls:" );    Number1 = Convert.ToInt32(Console.ReadLine());    Console.WriteLine ( "Type Second Number pls:" );    Number2 = Convert.ToInt32(Console.ReadLine ());    calculateNumbers = Number1 + Number2;    Console.WriteLine ( "To calculate, Number 1 + Number 2 is like: "  + calculateNumbers );    //manipulateTwoVariablesApp.recordVariablesClass.recordVariablesClassNumbers ();     manipulateTwoVariablesApp.PressAnyKeyClass.PressAnyKeyClasstoMoveOne ();    int  showNum1 = Number1;   int  showNum2 = Number2;    Console.WriteLine ( "You have enetered so far: Number1, Number2 Variables as like:"  +   "
" );    Console.WriteLine (showNum1);   Console.WriteLine (showNum2);      return  (calculateNumbers);    }   }   }

Another way, Main class does accept entry from public variables define as attached, problem only in secondary class return as it seems so:    using  System;      namespace  manipulateTwoVariablesApp   {   class  MainClass   {   public   static   int  Number1;    public   static   int  Number2;    public   static   int  calculateNumbers;    public   static   void  Main ( string [] args)   {   Number1 = 2;    Number2 = 6;    calculateNumbers = Number1 + Number2;    Console.WriteLine ( "Number 1 + Number 2 = "  + calculateNumbers );    //manipulateTwoVariablesApp.recordVariablesClass.recordVariablesClassNumbers ();     manipulateTwoVariablesApp.PressAnyKeyClass.PressAnyKeyClasstoMoveOne ();    int  showNum1 = Number1;   int  showNum2 = Number2;    Console.WriteLine ( "You have enetered so far: Number1, Number2 Variables as like:"  +   "
" );    Console.WriteLine (showNum1);   Console.WriteLine (showNum2);      }   }   }

Hi again...   I started another program the same way, photo attached below, when I called the variable from inside the method, the result ok, when I called it again after the method from the Main class, the result is 0 ...:        The code I have written in the main class is this:    using  System;      namespace  manipulateTwoVariablesApp   {   class  MainClass   {   public   static   void  Main ( string [] args)   {   manipulateTwoVariablesApp.recordVariablesClass.recordVariablesClassNumbers ();    manipulateTwoVariablesApp.PressAnyKeyClass.PressAnyKeyClasstoMoveOne ();    int  showNum1 = manipulateTwoVariablesApp.recordVariablesClass.Num1;    Console.WriteLine ( "You have enetered so far:"  + showNum1);       }   }   }   The code I have written in the secondary class is this:  using  System;      namespace  manipulateTwoVariablesApp   {   public   class  recordVariablesClass   {   public   static   int  Num1;    public   static   int  recordVariablesClassNumbers ()   {   Console.WriteLine ( "Welcome..." );   Console.WriteLine ( "
 Type the virst variale Number pls: " );   int  Num1 = Convert.ToInt32 (Console.ReadLine());    Console.WriteLine ( "you have enetered Num1: "  + Num1);    return  Num1;    }   }   }

Attach your code I will check

I changed the code for example to finally end with:  int  sendData = ((length * width * height)/100);    return  sendData; only single data but return still 0 as pic included...

Hi! Thank you for your reply and suuport...   The problem is that I tried the same method with one entry return (only length variable return length), still I could not record any data type int inside the variable length though ...   could be possible problem in cash memory?

Problem is this below line of code which you wriiten, Method EnterNumbers return type is int that means method can return single integer number only. return  (length, width, height) ;    for example if do calculation while returning like below it will work return  (length * width * height)    // or    return  (length + width * height) ;   // or    return  (length + width + height) ;   // ok    return  (length - width - height) ;  // etc     Lets say for example if you want return all these three variable values then your method retrun type should be of array or list type int
