Access WPF object by string variable

Question

I have x ListViews in my xaml Form:

In my program I can access them directly with lvExt1.Items or similar.

I would like to access those within a function that has the number as parameter

Something like:

privat void accessListView(string number){

   return lvlExt"number".Items;
}

I do realize it may be something completely different, but only to express what I am trying to do.

May be return (this.FindName("lvlExt" + number) as ListView).Items — Mike Debela

or LogicalTreeHelper.FindLogicalNode(this, "lvlExt" + number) — Steve

Two ways:

Use the way that WPF provided:

var lvlExt = this.FindName("lvlExt" + number) as ListView;

var lvlExt = LogicalTreeHelper.FindLogicalNode(this, "lvlExt" + number);
Use an array to reference:

var lvlExts = new ListView[3];

...

var lvlExt =ListView[number];
