C# - Winforms - Global Variables

Question

I want some variables to be global across the the project and accessible in every form. How can I do this?

Answer 1

yes you can by using static class. like this:

static class Global
{
    private static string _globalVar = "";

    public static string GlobalVar
    {
        get { return _globalVar; }
        set { _globalVar = value; }
    }
}

and for using any where you can write:

GlobalClass.GlobalVar = "any string value"

Answer 2

Or you could put your globals in the app.config

Answer 3

public static MyGlobals
{
  public static string Global1 = "Hello";
  public static string Global2 = "World";
}

public class Foo
{

    private void Method1()
    {
       string example = MyGlobals.Global1;
       //etc
    }
}

Answer 4

You can use static class or Singleton pattern.

Access them by
