Esempio

Nell'esempio seguente viene definito un operatore di confronto (ByFileExtension) utilizzato per costruire un set ordinato che ordina i nomi di file in base alle relative estensioni. Questo esempio di codice fa parte di un esempio più ampio fornito per la SortedSet<T> classe .

// Create a sorted set using the ByFileExtension comparer.
var mediaFiles1 = new SortedSet<string>(new ByFileExtension());

' Create a sorted set using the ByFileExtension comparer.
Dim mediaFiles1 As New SortedSet(Of String)(New ByFileExtension)

// Defines a comparer to create a sorted set
// that is sorted by the file extensions.
public class ByFileExtension : IComparer<string>
{
    string xExt, yExt;

    CaseInsensitiveComparer caseiComp = new CaseInsensitiveComparer();

    public int Compare(string x, string y)
    {
        // Parse the extension from the file name.
        xExt = x.Substring(x.LastIndexOf(".") + 1);
        yExt = y.Substring(y.LastIndexOf(".") + 1);

        // Compare the file extensions.
        int vExt = caseiComp.Compare(xExt, yExt);
        if (vExt != 0)
        {
            return vExt;
        }
        else
        {
            // The extension is the same,
            // so compare the filenames.
            return caseiComp.Compare(x, y);
        }
    }
}

' Defines a comparer to create a sorted set
' that is sorted by the file extensions.
Public Class ByFileExtension
    Implements IComparer(Of String)
    Dim xExt, yExt As String

    Dim caseiComp As CaseInsensitiveComparer = _
                        New CaseInsensitiveComparer
    Public Function Compare(x As String, y As String) _
        As Integer Implements IComparer(Of String).Compare
        ' Parse the extension from the file name.
        xExt = x.Substring(x.LastIndexOf(".") + 1)
        yExt = y.Substring(y.LastIndexOf(".") + 1)

        ' Compare the file extensions.
        Dim vExt As Integer = caseiComp.Compare(xExt, yExt)
        If vExt <> 0 Then
            Return vExt
        Else
            ' The extension is the same, 
            ' so compare the filenames. 
            Return caseiComp.Compare(x, y)
        End If
    End Function        
    
End Class

Parametri

Commenti

Gli elementi duplicati nella raccolta enumerabile non vengono copiati nella nuova istanza della SortedSet<T> classe e non vengono generate eccezioni.

Questo costruttore è un'operazione O(n log n) , dove n è il numero di elementi nel collection parametro .
