I caratteri Unicode sono suddivisi in categorie.The Unicode characters are divided into categories. Categoria del carattere è una delle relative proprietà.A character's category is one of its properties. Ad esempio, un carattere potrebbe essere una lettera maiuscola, una lettera minuscola, un numero a cifre decimali, un lettera, un numero, un segno di punteggiatura, simboli matematici o un simbolo di valuta.For example, a character might be an uppercase letter, a lowercase letter, a decimal digit number, a letter number, a connector punctuation, a math symbol, or a currency symbol. Il UnicodeCategory classe restituisce la categoria di un carattere Unicode.The UnicodeCategory class returns the category of a Unicode character. Per altre informazioni sui caratteri Unicode, vedere la Unicode Standard.For more information on Unicode characters, see the Unicode Standard.

Il GetUnicodeCategory metodo presuppone che ch corrisponde a un singolo carattere linguistico e restituisce la categoria.The GetUnicodeCategory method assumes that ch corresponds to a single linguistic character and returns its category. Ciò significa che, per le coppie di surrogati, viene restituito UnicodeCategory.Surrogate invece la categoria a cui appartiene il surrogato.This means that, for surrogate pairs, it returns UnicodeCategory.Surrogate instead of the category to which the surrogate belongs. Ad esempio, l'alfabeto ugaritico occupa i punti di codice 10380 U+10000 e U + 1039F.For example, the Ugaritic alphabet occupies code points U+10380 to U+1039F. L'esempio seguente usa il ConvertFromUtf32 metodo per creare un'istanza di una stringa che rappresenta UGARITIC LETTER ALPA (U + 10380), che è la prima lettera dell'alfabeto ugaritico.The following example uses the ConvertFromUtf32 method to instantiate a string that represents UGARITIC LETTER ALPA (U+10380), which is the first letter of the Ugaritic alphabet. Come l'output illustrato nell'esempio, il IsNumber(Char) restituzione del metodo false se viene passato il surrogato alto o surrogato basso di questo carattere.As the output from the example shows, the IsNumber(Char) method returns false if it is passed either the high surrogate or the low surrogate of this character.

int utf32 = 0x10380;       // UGARITIC LETTER ALPA
string surrogate = Char.ConvertFromUtf32(utf32);
foreach (var ch in surrogate)
   Console.WriteLine("U+{0:X4}: {1:G}", 
                     Convert.ToUInt16(ch), 
                     System.Globalization.CharUnicodeInfo.GetUnicodeCategory(ch));
// The example displays the following output:
//       U+D800: Surrogate
//       U+DF80: Surrogate
Dim utf32 As Integer = &h10380       ' UGARITIC LETTER ALPA
Dim surrogate As String = Char.ConvertFromUtf32(utf32)
For Each ch In surrogate
   Console.WriteLine("U+{0:X4}: {1:G}", 
                     Convert.ToUInt16(ch), 
                     System.Globalization.CharUnicodeInfo.GetUnicodeCategory(ch))
Next
' The example displays the following output:
'       U+D800: Surrogate
'       U+DF80: Surrogate

Si noti che CharUnicodeInfo.GetUnicodeCategory non restituisce sempre lo stesso UnicodeCategory come valore di Char.GetUnicodeCategory metodo quando viene passato un carattere specifico come parametro.Note that CharUnicodeInfo.GetUnicodeCategory does not always return the same UnicodeCategory value as the Char.GetUnicodeCategory method when passed a particular character as a parameter. Il CharUnicodeInfo.GetUnicodeCategory metodo è progettato in modo da riflettere la versione corrente dello standard Unicode.The CharUnicodeInfo.GetUnicodeCategory method is designed to reflect the current version of the Unicode standard. Al contrario, sebbene il Char.GetUnicodeCategory metodo in genere riflette la versione corrente dello standard Unicode, potrebbe restituire categoria del carattere in base a una versione precedente dello standard o potrebbe restituire una categoria che è diverso dallo standard corrente per mantenere la compatibilità con le versioni precedenti.In contrast, although the Char.GetUnicodeCategory method usually reflects the current version of the Unicode standard, it might return a character's category based on a previous version of the standard, or it might return a category that differs from the current standard to preserve backward compatibility.

Se il Char oggetto nella posizione index è il primo carattere di una coppia di surrogati valide, il GetUnicodeCategory(String, Int32) metodo restituisce la categoria Unicode della coppia di surrogati invece di restituire UnicodeCategory.Surrogate.If the Char object at position index is the first character of a valid surrogate pair, the GetUnicodeCategory(String, Int32) method returns the Unicode category of the surrogate pair instead of returning UnicodeCategory.Surrogate. Ad esempio, l'alfabeto ugaritico occupa i punti di codice 10380 U+10000 e U + 1039F.For example, the Ugaritic alphabet occupies code points U+10380 to U+1039F. L'esempio seguente usa il ConvertFromUtf32 metodo per creare un'istanza di una stringa che rappresenta UGARITIC LETTER ALPA (U + 10380), che è la prima lettera dell'alfabeto ugaritico.The following example uses the ConvertFromUtf32 method to instantiate a string that represents UGARITIC LETTER ALPA (U+10380), which is the first letter of the Ugaritic alphabet. Come l'output illustrato nell'esempio, il GetUnicodeCategory(String, Int32) restituzione del metodo UnicodeCategory.OtherLetter se viene passata surrogato alto di questo carattere, che indica che viene considerata la coppia di surrogati.As the output from the example shows, the GetUnicodeCategory(String, Int32) method returns UnicodeCategory.OtherLetter if it is passed the high surrogate of this character, which indicates that it considers the surrogate pair. Tuttavia, se viene passata surrogato basso, prende in considerazione solo il surrogato basso in isolamento e restituisce UnicodeCategory.Surrogate.However, if it is passed the low surrogate, it considers only the low surrogate in isolation and returns UnicodeCategory.Surrogate.

int utf32 = 0x10380;       // UGARITIC LETTER ALPA
string surrogate = Char.ConvertFromUtf32(utf32);
for (int ctr = 0; ctr < surrogate.Length; ctr++)
   Console.WriteLine("U+{0:X4}: {1:G}", 
                     Convert.ToUInt16(surrogate[ctr]), 
                     System.Globalization.CharUnicodeInfo.GetUnicodeCategory(surrogate, ctr));
// The example displays the following output:
//       U+D800: OtherLetter
//       U+DF80: Surrogate      
Dim utf32 As Integer = &h10380       ' UGARITIC LETTER ALPA
Dim surrogate As String = Char.ConvertFromUtf32(utf32)
For ctr As Integer = 0 To surrogate.Length - 1
   Console.WriteLine("U+{0:X4}: {1:G}", 
                     Convert.ToUInt16(surrogate(ctr)), 
                     System.Globalization.CharUnicodeInfo.GetUnicodeCategory(surrogate, ctr))
Next
' The example displays the following output:
'       U+D800: OtherLetter
'       U+DF80: Surrogate      

Si noti che CharUnicodeInfo.GetUnicodeCategory metodo non restituisce sempre lo stesso UnicodeCategory come valore di Char.GetUnicodeCategory metodo quando viene passato un carattere specifico come parametro.Note that CharUnicodeInfo.GetUnicodeCategory method does not always return the same UnicodeCategory value as the Char.GetUnicodeCategory method when passed a particular character as a parameter. Il CharUnicodeInfo.GetUnicodeCategory metodo è progettato in modo da riflettere la versione corrente dello standard Unicode.The CharUnicodeInfo.GetUnicodeCategory method is designed to reflect the current version of the Unicode standard. Al contrario, sebbene il Char.GetUnicodeCategory metodo in genere riflette la versione corrente dello standard Unicode, potrebbe restituire categoria del carattere in base a una versione precedente dello standard o potrebbe restituire una categoria che è diverso dallo standard corrente per mantenere la compatibilità con le versioni precedenti.In contrast, although the Char.GetUnicodeCategory method usually reflects the current version of the Unicode standard, it might return a character's category based on a previous version of the standard, or it might return a category that differs from the current standard to preserve backward compatibility.
