How can access variable from different class?

[Autostrad]

Below; I have 2 classes (forms), Namely, "PrintOneEmploy ee" and "DeleteOne" . In class "PrintOneEmploy ee";
I want to declare a variable with name of "fileName" to contain the name of the file "Main\\_1Main.t xt".
Later on, when I wanted to access the variable "fileName" in the other class, namely, "DeleteOne" . The
compiler show an error that the variable is undeclared. What should I do to access the variable "fileName"
in the the other class "DeleteOne" ? I am aware of the scope of the variable inside the brackets,
but I am confused about the scope of the different classes.

/*************** *************** *************** *************/

#pragma once
#using <System.dll> 
#using <System.Windows.Forms.dll>  
#using <System.Drawing.dll>  

#include "DeleteOne.h"

#include "Time.h"
#using <mscorlib.dll>

using namespace System;
using namespace System::IO;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System::Windows::Forms;
using namespace System::Data;
using namespace System::Drawing;
using namespace System::Drawing::Printing;  

namespace TimeTracking 
{
 
 public ref class PrintOneEmployee : public System::Windows::Forms::Form
 {
 
 

    private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) 
    {   
       
    { 
    streamToPrint = gcnew StreamReader(  "Main\\_1Main.txt" );
    
    String^ fileName = "Main\\_1Main.txt"String^ fileName;
    } 
    
      
    }
     
    
 };
}

/*************** *************** *************** *************** *********/

#pragma once

#include "Time.h"
//#include "PrintOneEmployee.h"
#using <mscorlib.dll>

using namespace System;
using namespace System::IO;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System::Windows::Forms;
using namespace System::Data;
using namespace System::Drawing;

namespace TimeTracking 
{
 
 public ref class DeleteOne : public System::Windows::Forms::Form
 {
 

   private: System::Void OkBotton_Click(System::Object^  sender, System::EventArgs^  e) 
    {
     
     FileInfo^ fi = gcnew FileInfo(FileName);
     fi->Delete();
     
    }
 
 };
}

1) They are not the same name, it's case-sensitive
2) if there are more than one instance of PrintOneEmploye e, how will DeleteOne know which to use?
Then you can write some public getter to access class member.
