Unicode 文字は、カテゴリに分類されます。The Unicode characters are divided into categories. 文字のカテゴリでは、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、大文字、小文字、10 進数、文字数、コネクタ句読点、数学記号、または通貨記号文字があります。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、次を参照してください。、 Unicode 標準します。For more information on Unicode characters, see the Unicode Standard.

GetUnicodeCategoryメソッドch単一言語の文字に対応し、そのカテゴリを返します。The GetUnicodeCategory method assumes that ch corresponds to a single linguistic character and returns its category. つまり、サロゲート ペアを返しますUnicodeCategory.Surrogateサロゲートが所属するカテゴリではなく。This means that, for surrogate pairs, it returns UnicodeCategory.Surrogate instead of the category to which the surrogate belongs. たとえば、Ugaritic アルファベットは、コード ポイント 10380 U + U + 1039F を占有します。For example, the Ugaritic alphabet occupies code points U+10380 to U+1039F. 次の例では、 ConvertFromUtf32 Ugaritic アルファベット順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するメソッド。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. 例を示しますから出力として、IsNumber(Char)メソッドを返します。false場合は、上位サロゲートまたは下位サロゲートのこの文字のいずれかを渡すことができます。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、次を参照してください。、 Unicode 標準します。For more information on Unicode characters, see the Unicode Standard.

場合、Char位置にあるオブジェクトindex、有効なサロゲート ペアの最初の文字は、GetUnicodeCategory(String, Int32)メソッドが返す代わりに、サロゲート ペアの Unicode カテゴリを返しますUnicodeCategory.Surrogate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 アルファベットは、コード ポイント 10380 U + U + 1039F を占有します。For example, the Ugaritic alphabet occupies code points U+10380 to U+1039F. 次の例では、 ConvertFromUtf32 Ugaritic アルファベット順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するメソッド。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. 例を示しますから出力として、GetUnicodeCategory(String, Int32)メソッドを返します。UnicodeCategory.OtherLetter場合は、この文字は、サロゲート ペアとして認識していることを示しますの上位サロゲートが渡されます。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、下位のサロゲート、渡される場合の分離の下位サロゲートのみを考慮し、返しますUnicodeCategory.Surrogateします。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      

なおCharUnicodeInfo.GetUnicodeCategoryメソッドは常に返しません同じUnicodeCategory値として、Char.GetUnicodeCategoryメソッド パラメーターとして渡されると、特定の文字。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、ですが、Char.GetUnicodeCategoryメソッドは、現在のバージョンの Unicode 標準は、通常が反映されますまたは、標準の以前のバージョンに基づく文字のカテゴリを返す可能性があります、とは異なるカテゴリには、現在の標準から返されます。旧バージョンとの互換性を維持します。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.
