declare a global variable

[ajinkya ragalwa]

Need to know, how can i declare a variable as global
in a form and if i can use it in another.

(I hope this isn't a vague question)


Thanks and regards

Just declare it as public in your form Form1, then refer to it as Form1.variable in your second form.

Generally you should try to avoid using globals; however, it's still sometimes appropriate to do so. In these cases, I'd recommend making yourself a static class called Globals, with public static members.

namespace YourAppName.Global
{
  public static class Globals
  {
    public float PI = 3.141592654;
    public string VERSION = "v1.54";
    ...
  }
}

Now, if you include the namespace (and a reference, where appropriate), you can access it anywhere in your code using...

Console.WriteLine(Globals.PI);
Console.WriteLine(Globals.VERSION);

I hope that helps!
