Comentários

Os caracteres Unicode são divididos em categorias.The Unicode characters are divided into categories. Categoria de um caractere é uma de suas propriedades.A character's category is one of its properties. Por exemplo, um caractere pode ser uma letra maiuscula, uma letra minúscula, um número de dígito decimal, um letra, um número, uma pontuação de conector, um símbolo matemático ou um símbolo de moeda.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. O UnicodeCategory classe retorna a categoria de um caractere Unicode.The UnicodeCategory class returns the category of a Unicode character. Para obter mais informações sobre caracteres Unicode, consulte o padrão Unicode.For more information on Unicode characters, see the Unicode Standard.

O GetUnicodeCategory método pressupõe que ch corresponde a um único caractere linguístico e retorna sua categoria.The GetUnicodeCategory method assumes that ch corresponds to a single linguistic character and returns its category. Isso significa que, para os pares substitutos, ela retorna UnicodeCategory.Surrogate em vez da categoria à qual pertence o substituto.This means that, for surrogate pairs, it returns UnicodeCategory.Surrogate instead of the category to which the surrogate belongs. Por exemplo, o alfabeto Ugaritic ocupa pontos de código U + 10380 a U + 1039F.For example, the Ugaritic alphabet occupies code points U+10380 to U+1039F. O exemplo a seguir usa o ConvertFromUtf32 método para instanciar uma cadeia de caracteres que representa o UGARITIC LETRA ALPA (U + 10380), que é a primeira letra do alfabeto Ugaritic.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. Como a saída do exemplo mostra, o IsNumber(Char) método retorna false se ele é transmitido o substituto alto ou baixo alternativo desse caractere.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

Observe que CharUnicodeInfo.GetUnicodeCategory nem sempre retorna o mesmo UnicodeCategory de valor como o Char.GetUnicodeCategory quando passado um determinado caractere como um parâmetro de método.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. O CharUnicodeInfo.GetUnicodeCategory método foi projetado para refletir a versão atual do padrão Unicode.The CharUnicodeInfo.GetUnicodeCategory method is designed to reflect the current version of the Unicode standard. Por outro lado, embora o Char.GetUnicodeCategory método geralmente reflete a versão atual do padrão Unicode, ela pode retornar com base em uma versão anterior do padrão de categoria de um caractere ou ela pode retornar uma categoria que seja diferente do padrão atual para preserve a compatibilidade com versões anteriores.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 o Char objeto na posição index é o primeiro caractere de um par substituto válido, o GetUnicodeCategory(String, Int32) método retorna a categoria Unicode do par alternativo em vez de retornar 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. Por exemplo, o alfabeto Ugaritic ocupa pontos de código U + 10380 a U + 1039F.For example, the Ugaritic alphabet occupies code points U+10380 to U+1039F. O exemplo a seguir usa o ConvertFromUtf32 método para instanciar uma cadeia de caracteres que representa o UGARITIC LETRA ALPA (U + 10380), que é a primeira letra do alfabeto Ugaritic.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. Como a saída do exemplo mostra, o GetUnicodeCategory(String, Int32) método retorna UnicodeCategory.OtherLetter se ele é transmitido o substituto alto desse caractere, o que indica que ele considera o par substituto.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. No entanto, se ele for passado o substituto baixo, ele considera somente o substituto baixo em isolamento e retorna 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      

Observe que CharUnicodeInfo.GetUnicodeCategory método nem sempre retorna o mesmo UnicodeCategory de valor como o Char.GetUnicodeCategory quando passado um determinado caractere como um parâmetro de método.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. O CharUnicodeInfo.GetUnicodeCategory método foi projetado para refletir a versão atual do padrão Unicode.The CharUnicodeInfo.GetUnicodeCategory method is designed to reflect the current version of the Unicode standard. Por outro lado, embora o Char.GetUnicodeCategory método geralmente reflete a versão atual do padrão Unicode, ela pode retornar com base em uma versão anterior do padrão de categoria de um caractere ou ela pode retornar uma categoria que seja diferente do padrão atual para preserve a compatibilidade com versões anteriores.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.
