Get public variable from another class

I have a class where there's a public static variable that I want to access from another class. Here's the class : In GlobalVariable.cs

public class GlobalVariable
{
    public static int MoisVS = 3;
}

And I want to access to "MoisVS" from another class. Here's the class : In ArretPage.cs

var globalvariable = new ProjetTN.Class.GlobalVariable();
globalvariable.MoisVS;  //<--- Make something like that.

I know it's possible in a WinForm app but is that possible in a Xamarin.forms app ?

I will break this into steps.

1) File -> New File -> General -> Choose Empty Class -> Name it (e.g.UICONTROL_NAMES)

2) Add the following: (Sample code)

using System;

namespace iOSControls.HelperClass
{
    public static class UICONTROL_NAMES
    {
        public const string textField = "Text Fields";
        public const string inputTextField = "Input types - TextFields";
        public const string button = "Buttons";
        public const string label = "Label";
}

Have a note:

UICONTROL_NAMES class is inside a folder group called HelperClass and iOSControls is the project name.

3) On your ViewController.cs, add namespace directive.

using iOSControls.HelperClass;
using Foundation;

4) Access const strings in UICONTROL NAMES:

string controlName = UICONTROL_NAMES.textField;

You defined your MoisVS as static so you can't access it from an instance variable. Accessing static members of a class you're using the class name itself. So for example accessing your MoisVS will look like:

GlobalVariable.MoisVS

If you want to accesss it as an instance property you have to change your class to:

public class GlobalVariable
{
    public int MoisVS = 3;
}

If there are only static or const values in your class. You can also decide to make your whole class static

public static class GlobalVariable
{
    public static int MoisVS = 3;
    public const string MyString = "";
}

this will prevent you from using the new keyword to create an instance of that class.
