Dictionary<TKey, TValue>.Values Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets a collection containing the values in the Dictionary<TKey, TValue>.

Namespace:  System.Collections.Generic
Assembly:  mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public ReadOnly Property Values As Dictionary<(Of <(<'TKey, TValue>)>)>..::..ValueCollection

public Dictionary<(Of <(<'TKey, TValue>)>)>..::..ValueCollection Values { get; }

Remarks

The order of the values in the Dictionary<TKey, TValue>.ValueCollection is unspecified, but it is the same order as the associated keys in the Dictionary<TKey, TValue>.KeyCollection returned by the Keys property.

The returned Dictionary<TKey, TValue>.ValueCollection is not a static copy; instead, the Dictionary<TKey, TValue>.ValueCollection refers back to the values in the original Dictionary<TKey, TValue>. Therefore, changes to the Dictionary<TKey, TValue> continue to be reflected in the Dictionary<TKey, TValue>.ValueCollection.

Getting the value of this property is an O(1) operation.

Examples

This code example shows how to enumerate the values in the dictionary using the Values property, and how to enumerate the keys and values in the dictionary.

This code example is part of a larger example provided for the Dictionary<TKey, TValue> class.

' To get the values alone, use the Values property.
Dim valueColl As  _
    Dictionary(Of String, String).ValueCollection = _
    openWith.Values

' The elements of the ValueCollection are strongly typed
' with the type that was specified for dictionary values.
outputBlock.Text &= vbCrLf
For Each s As String In valueColl
   outputBlock.Text &= String.Format("Value = {0}", s) & vbCrLf
Next s


...


' When you use foreach to enumerate dictionary elements,
' the elements are retrieved as KeyValuePair objects.
outputBlock.Text &= vbCrLf
For Each kvp As KeyValuePair(Of String, String) In openWith
   outputBlock.Text &= String.Format("Key = {0}, Value = {1}", _
       kvp.Key, kvp.Value) & vbCrLf
Next kvp

// To get the values alone, use the Values property.
Dictionary<string, string>.ValueCollection valueColl =
    openWith.Values;

// The elements of the ValueCollection are strongly typed
// with the type that was specified for dictionary values.
outputBlock.Text += "\n";
foreach (string s in valueColl)
{
   outputBlock.Text += String.Format("Value = {0}", s) + "\n";
}


...


// When you use foreach to enumerate dictionary elements,
// the elements are retrieved as KeyValuePair objects.
outputBlock.Text += "\n";
foreach (KeyValuePair<string, string> kvp in openWith)
{
   outputBlock.Text += String.Format("Key = {0}, Value = {1}",
       kvp.Key, kvp.Value) + "\n";
}
