DebuggerBrowsableState Enum


Provides display instructions for the debugger.

public enum class DebuggerBrowsableState
public enum DebuggerBrowsableState
public enum DebuggerBrowsableState
type DebuggerBrowsableState = 
Public Enum DebuggerBrowsableState


Collapsed 2

Show the element as collapsed.

Never 0

Never show the element.

RootHidden 3

Do not display the root element; display the child elements if the element is a collection or array of items.


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.

property array<KeyValuePairs^>^ Keys
    array<KeyValuePairs^>^ get()
        array<KeyValuePairs^>^ keys = gcnew array<KeyValuePairs^>(hashtable->Count);

        IEnumerator^ ie = hashtable->Keys->GetEnumerator();
        int i = 0;
        Object^ key;
        while (ie->MoveNext())
            key = ie->Current;
            keys[i] = gcnew KeyValuePairs(hashtable, key, hashtable[key]);
        return keys;
public KeyValuePairs[] Keys
        KeyValuePairs[] keys = new KeyValuePairs[hashtable.Count];

        int i = 0;
        foreach(object key in hashtable.Keys)
            keys[i] = new KeyValuePairs(hashtable, key, hashtable[key]);
        return keys;
<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


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.
