Il valore numerico è una proprietà di caratteri Unicode che si applica solo ai caratteri numerici, che includono frazioni, pedice, apice, numeri romani, numeratori di valuta, numeri incircuiti e cifre specifiche dello script. Per altre informazioni sui caratteri Unicode, vedere Lo standard Unicode.

Il GetNumericValue(Char) metodo presuppone che ch corrisponda a un singolo carattere linguistico e controlla se tale carattere può essere convertito in una cifra decimale. Tuttavia, alcuni numeri nello standard Unicode sono rappresentati da due Char oggetti che formano una coppia di surrogati. Ad esempio, il sistema di numerazione dell'Egeo è costituito da punti di codice da U+10107 a U+10133. Nell'esempio seguente viene utilizzato il metodo per creare un'istanza ConvertFromUtf32 di una stringa che rappresenta IL NUMERO 1 DELL'EGEO. Come illustrato nell'output dell'esempio, il GetNumericValue(Char) metodo restituisce -1 se viene passato un surrogato elevato o un surrogato basso di questo carattere.

int utf32 = 0x10107;       // AEGEAN NUMBER ONE
string surrogate = Char.ConvertFromUtf32(utf32);
foreach (var ch in surrogate)
   Console.WriteLine($"U+{(ushort)ch:X4}: {System.Globalization.CharUnicodeInfo.GetNumericValue(ch)}    ");

// The example displays the following output:
//       U+D800: -1
//       U+DD07: -1

Dim utf32 As Integer = &h10107       ' AEGEAN NUMBER ONE
Dim surrogate As String = Char.ConvertFromUtf32(utf32)
For Each ch In surrogate
   Console.WriteLine("U+{0:X4}: {1}    ", Convert.ToUInt16(ch), 
                     System.Globalization.CharUnicodeInfo.GetNumericValue(ch))
Next
' The example displays the following output:
'       U+D800: -1
'       U+DD07: -1

Se l'oggetto Char in corrispondenza della posizione index è il primo carattere di una coppia surrogata valida, il GetNumericValue(String, Int32) metodo determina se la coppia di surrogati forma una cifra numerica e, in caso affermativo, restituisce il valore numerico. Ad esempio, il sistema di numerazione dell'Egeo è costituito da punti di codice da U+10107 a U+10133. Nell'esempio seguente viene utilizzato il metodo per creare un'istanza ConvertFromUtf32 di una stringa che rappresenta ogni numero dell'Egeo. Come illustrato nell'output dell'esempio, il GetNumericValue(String, Int32) metodo restituisce il valore numerico corretto se viene passato il surrogato elevato di un numero dell'Egeo. Tuttavia, se viene passato il surrogato basso, considera solo il surrogato basso in isolamento e restituisce -1.

// Define a UTF32 value for each character in the
// Aegean numbering system.
for (int utf32 = 0x10107; utf32 <= 0x10133; utf32++) {
   string surrogate = Char.ConvertFromUtf32(utf32);
   for (int ctr = 0; ctr < surrogate.Length; ctr++)
      Console.Write("U+{0:X4} at position {1}: {2}     ",
                    Convert.ToUInt16(surrogate[ctr]), ctr,
                    System.Globalization.CharUnicodeInfo.GetNumericValue(surrogate, ctr));

   Console.WriteLine();
}
// The example displays the following output:
