public:
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
Parâmetros
- value
- CodeExpression
O objeto CodeExpression a ser localizado na coleção.The CodeExpression object to locate in the collection.

Exemplos
O exemplo a seguir pesquisa a presença de um CodeExpression objeto específico e usa o IndexOf método para obter o valor de índice no qual ele foi encontrado.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
