 int IndexOf(System::CodeDom::CodeExpression ^ value);
public int IndexOf (System.CodeDom.CodeExpression value);
member this.IndexOf : System.CodeDom.CodeExpression -> int
Public Function IndexOf (value As CodeExpression) As Integer

Parametri

value
CodeExpression CodeExpression CodeExpression CodeExpression

Oggetto CodeExpression da individuare nell'insieme.The CodeExpression object to locate in the collection.

Restituisce

Indice dell'oggetto specificato, se presente nell'insieme, in caso contrario -1.The index of the specified object, if found, in the collection; otherwise, -1.

Esempi

Nell'esempio seguente viene eseguita la ricerca della presenza di CodeExpression un oggetto specifico e IndexOf viene utilizzato il metodo per ottenere il valore di indice in corrispondenza del quale è stato trovato.The following example searches for the presence of a specific CodeExpression object and uses the IndexOf method to get the index value at which it was found.

// Tests for the presence of a CodeExpression in the 
// collection, and retrieves its index if it is found.
CodeExpression^ testComment = gcnew CodePrimitiveExpression( true );
int itemIndex = -1;
if ( collection->Contains( testComment ) )
   itemIndex = collection->IndexOf( testComment );
// Tests for the presence of a CodeExpression in the 
// collection, and retrieves its index if it is found.
CodeExpression testComment = new CodePrimitiveExpression(true);
int itemIndex = -1;
if( collection.Contains( testComment ) )
    itemIndex = collection.IndexOf( testComment );
' Tests for the presence of a CodeExpression in the 
' collection, and retrieves its index if it is found.
Dim testComment = New CodePrimitiveExpression(True)
Dim itemIndex As Integer = -1
If collection.Contains(testComment) Then
    itemIndex = collection.IndexOf(testComment)
End If
