Unicode 文字は、カテゴリに分類されます。The Unicode characters are divided into categories. 文字のカテゴリは、そのプロパティの1つです。A character's category is one of its properties. たとえば、文字には、大文字、小文字、10進数字、文字番号、コネクタの句読点、数学記号、通貨記号などがあります。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. UnicodeCategory クラスは、Unicode 文字のカテゴリを返します。The UnicodeCategory class returns the category of a Unicode character. Unicode 文字の詳細については、「 Unicode 標準」を参照してください。For more information on Unicode characters, see the Unicode Standard.

GetUnicodeCategory メソッドは、ch が1つの言語に対応し、そのカテゴリを返すことを前提としています。The GetUnicodeCategory method assumes that ch corresponds to a single linguistic character and returns its category. これは、サロゲートペアの場合、サロゲートが属するカテゴリではなく UnicodeCategory.Surrogate を返すことを意味します。This means that, for surrogate pairs, it returns UnicodeCategory.Surrogate instead of the category to which the surrogate belongs. たとえば、Ugaritic のアルファベットは、コードポイント U + 10380 を U + 1039F に占有します。For example, the Ugaritic alphabet occupies code points U+10380 to U+1039F. 次の例では、ConvertFromUtf32 メソッドを使用して、Ugaritic アルファベットの最初の文字である UGARITIC 文字 ALPA (U + 10380) を表す文字列をインスタンス化します。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. この例の出力が示すように、IsNumber(Char) メソッドは、この文字の上位サロゲートまたは下位サロゲートのいずれかが渡された場合に false を返します。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

注意 CharUnicodeInfo.GetUnicodeCategoryは特定の文字がパラメーターとして渡されると、Char.GetUnicodeCategoryメソッドと常に同じUnicodeCategory値を返すとは限りません。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. CharUnicodeInfo.GetUnicodeCategoryメソッドは現在のバージョンの Unicode 標準を反映するように設計されています。The CharUnicodeInfo.GetUnicodeCategory method is designed to reflect the current version of the Unicode standard. これに対し、Char.GetUnicodeCategoryメソッドは通常、現在のバージョンの Unicode 標準を反映しますが、以前のバージョンの標準に基づく文字のカテゴリまたは、旧バージョンとの互換性を維持するために現在の標準とは異なるカテゴリを返す場合があります。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.

UnicodeCategory クラスは、Unicode 文字のカテゴリを返します。The UnicodeCategory class returns the category of a Unicode character. Unicode 文字の詳細については、「 Unicode 標準」を参照してください。For more information on Unicode characters, see the Unicode Standard.

index 位置にある Char オブジェクトが有効なサロゲートペアの最初の文字である場合、GetUnicodeCategory(String, Int32) メソッドは UnicodeCategory.Surrogateを返す代わりに、サロゲートペアの Unicode カテゴリを返します。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. たとえば、Ugaritic のアルファベットは、コードポイント U + 10380 を U + 1039F に占有します。For example, the Ugaritic alphabet occupies code points U+10380 to U+1039F. 次の例では、ConvertFromUtf32 メソッドを使用して、Ugaritic アルファベットの最初の文字である UGARITIC 文字 ALPA (U + 10380) を表す文字列をインスタンス化します。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. この例の出力が示すように、GetUnicodeCategory(String, Int32) メソッドは、サロゲートペアを考慮していることを示す、この文字の上位サロゲートが渡された場合に UnicodeCategory.OtherLetter を返します。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. ただし、下位サロゲートが渡された場合は、下位サロゲートのみが分離され、UnicodeCategory.Surrogateが返されます。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      

CharUnicodeInfo.GetUnicodeCategory メソッドは、特定の文字をパラメーターとして渡したときに、必ずしも Char.GetUnicodeCategory メソッドと同じ UnicodeCategory 値を返さないことに注意してください。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. CharUnicodeInfo.GetUnicodeCategoryメソッドは現在のバージョンの Unicode 標準を反映するように設計されています。The CharUnicodeInfo.GetUnicodeCategory method is designed to reflect the current version of the Unicode standard. これに対し、Char.GetUnicodeCategoryメソッドは通常、現在のバージョンの Unicode 標準を反映しますが、以前のバージョンの標準に基づく文字のカテゴリまたは、旧バージョンとの互換性を維持するために現在の標準とは異なるカテゴリを返す場合があります。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.
