DebuggerBrowsableState is used to simplify the view in the debug window. Use of the DebuggerDisplayAttribute attribute using this enumeration can result in a much simpler and more pleasing view in the debug window. See the DebuggerBrowsableAttribute class for information on the use of this enumeration.

The following code example shows the use of the DebuggerBrowsableState enumeration to instruct the debugger to not display the root (property name) of the Keys property, but to display the elements of the array that Keys gets. This code example is part of a larger example provided for the DebuggerDisplayAttribute class.

<DebuggerBrowsable(DebuggerBrowsableState.RootHidden)> _
ReadOnly Property Keys as KeyValuePairs()
        Dim nkeys(hashtable.Count) as KeyValuePairs

        Dim i as Integer = 0
        For Each key As Object In hashtable.Keys
            nkeys(i) = New KeyValuePairs(hashtable, key, hashtable(key))
            i = i + 1
        Return nkeys
    End Get 
End Property
