Question

The following line of code

TreeView treeview = (TreeView)currentGroup.Content;

lists an error

‘TreeView’ is an ambiguous reference between ‘System.Windows.Forms.TreeView‘ and ‘System.Windows.Controls.TreeView‘

I know the reason as I need to explicitly state which reference to use as both have TreeView eg :

System.Windows.Controls.TreeView treeview = (System.Windows.Controls.TreeView)currentGroup.Content;

What is best practice for this? Is there another(neater) way of defining which reference TreeView must use if used extensively through several methods?

Answer 1

If you use particularly System.Windows.Forms.TreeView for example, you just add

using TreeView = System.Windows.Forms.TreeView;

into your using statements list and within this class by default the compiler will be assuming System.Windows.Forms.TreeView when you use TreeView.
