WinForm: How to use value of one Form in another Form

Question

#?Probem?
Supoose i have two Forms (Settings.cs and MainForm.cs) and a back-end class for methods(let, Compose.cs).

And, i want my Settings.cs to assign a DestinationFolder path(string) to Compose.cs file( public string destination{get;set;}) . So, that i can access that path in my MainForm.cs form.

But, when i access that 'destination' property it returns NULL. Though, i assigned my Folder Destination.

I suspect that the BackEnd object which MainForm is using is not the same as the BackEnd object which Settings is using and this is why the destination property returns null in the former. If this is the case, I'd make the destination property static so that it can be accessed like this without creating an object : BackEnd.destination.

Every time you call 'new BackEnd()' it creates a new and different object from any that have been created before, with its own set of fields and automatic properties. Whilst it's not impossible to share an object between forms, the code to do so is relatively messy compared to just making the property 'static' which ensures that there's only one copy of the underlying field.

It doesn't matter. If you've used 'new' twice, two different objects will be created.

That i know, whenever new Object is created then every single instance f that class. But, here i have just switched from one EVENT to another.
