public:
 virtual bool Contains(System::Web::SiteMapNode ^ value);
public virtual bool Contains (System.Web.SiteMapNode value);
abstract member Contains : System.Web.SiteMapNode -> bool
override this.Contains : System.Web.SiteMapNode -> bool
Public Overridable Function Contains (value As SiteMapNode) As Boolean

Paramètres

value
SiteMapNode

SiteMapNode à rechercher dans SiteMapNodeCollection.

Retours

Boolean

true si SiteMapNodeCollection contient le SiteMapNode spécifié ; sinon, false.

Exemples

L’exemple de code suivant montre comment utiliser les méthodes et IndexOf les Contains méthodes de la SiteMapNodeCollection classe. Le code vérifie deux fournisseurs et AspNetXmlSiteMapProvider MyXmlSiteMapProvider, pour les nœuds enfants du nœud racine qui sont des doublons.

String providername1 = "AspNetXmlSiteMapProvider";
String providername2 = "MyXmlSiteMapProvider";
SiteMapProviderCollection providers = SiteMap.Providers;

if (providers[providername1] != null && providers[providername2] != null)
{
  SiteMapProvider provider1 = providers[providername1];
  SiteMapProvider provider2 = providers[providername2];
  SiteMapNodeCollection collection1 = provider1.RootNode.ChildNodes;
  SiteMapNodeCollection collection2 = provider2.RootNode.ChildNodes;
  int matches = 0;
  foreach (SiteMapNode node in collection1)
  {
    if (collection2.Contains(node))
    {
      Response.Write("Match found at " +
        providername1 + ", index = " +
        collection1.IndexOf(node) + " with " +
        providername2 + ", index = " +
        collection2.IndexOf(node) + ".<br />");
      matches++;
    }
  }
  Response.Write("Number of matches found = " +
    matches.ToString() + ".");
}
else
{
  Response.Write(providername1 + " or " +
    providername2 + " not found.");
}

Dim providername1 As String = "xAspNetXmlSiteMapProvider"
Dim providername2 As String = "MyXmlSiteMapProvider"
Dim providers As SiteMapProviderCollection = SiteMap.Providers

If Not (providers(providername1) Is Nothing) AndAlso Not (providers(providername2) Is Nothing) Then
  Dim provider1 As SiteMapProvider = providers(providername1)
  Dim provider2 As SiteMapProvider = providers(providername2)
  Dim collection1 As SiteMapNodeCollection = provider1.RootNode.ChildNodes
  Dim collection2 As SiteMapNodeCollection = provider2.RootNode.ChildNodes
  Dim matches As Integer = 0
  Dim node As SiteMapNode
  For Each node In collection1
    If collection2.Contains(node) Then
      Response.Write("Match found at " & _
      providername1 & ", index = " & _
      collection1.IndexOf(node) & " with " & _
      providername2 & ", index = " & _
      collection2.IndexOf(node) & ".<br />")
      matches += 1
    End If
  Next node
  Response.Write("Number of matches found = " & _
  matches.ToString() + ".")
Else
  Response.Write(providername1 & " or " & _
  providername2 & " not found.")
End If

Remarques

La Contains méthode détermine l’égalité en appelant la Object.Equals méthode.
