Comentários

Se value for positivo e toBase for 2, 8 ou 16, a cadeia de caracteres retornada usará a representação de entrada e magnitude.If value is positive and toBase is 2, 8, or 16, the returned string uses sign-and-magnitude representation. Se value for negativo e toBase for 2, 8 ou 16, a cadeia de caracteres retornada usará a representação complementar de duas.If value is negative and toBase is 2, 8, or 16, the returned string uses two's complement representation. Isso significa que o bit de ordem superior do byte de ordem superior (bit 15) é interpretado como o bit de sinal.This means that the high-order bit of the high-order byte (bit 15) is interpreted as the sign bit. Se o ToString(Int16, Int32) método for chamado para criar uma cadeia de caracteres que posteriormente será convertida de volta em um número, um método correspondente que assume uma representação numérica semelhante deve ser chamado para executar a conversão.If the ToString(Int16, Int32) method is called to create a string that will later be converted back to a number, a corresponding method that assumes a similar numeric representation should be called to perform the conversion. Esses métodos incluem Convert.ToInt16(String, Int32) e Int16.Parse(String, NumberStyles).Such methods include Convert.ToInt16(String, Int32) and Int16.Parse(String, NumberStyles).

A conversão usa a cultura invariável e o objeto NumberFormatInfo personalizado.The conversion uses both the invariant culture and the custom NumberFormatInfo object. A saída indica que essas informações de formatação não são usadas porque, por padrão, o especificador de formato "G" não inclui um sinal positivo com valores positivos.The output indicates that this formatting information is not used, because by default the "G" format specifier does not include a positive sign with positive values.

ulong number = UInt64.MaxValue;
System.Globalization.NumberFormatInfo nfi = new System.Globalization.NumberFormatInfo();
nfi.NegativeSign = "~";
nfi.PositiveSign = "!";

Comentários

Se value for positivo e toBase for 2, 8 ou 16, a cadeia de caracteres retornada usará a representação de entrada e magnitude.If value is positive and toBase is 2, 8, or 16, the returned string uses sign-and-magnitude representation. Se value for negativo e toBase for 2, 8 ou 16, a cadeia de caracteres retornada usará a representação complementar de duas.If value is negative and toBase is 2, 8, or 16, the returned string uses two's complement representation. Isso significa que o bit de ordem superior do byte de ordem mais alta (bit 31) é interpretado como o bit de sinal.This means that the high-order bit of the highest-order byte (bit 31) is interpreted as the sign bit. Se o ToString(Int32, Int32) método for chamado para criar uma cadeia de caracteres que posteriormente será convertida de volta em um número, um método correspondente que assume uma representação numérica semelhante deve ser chamado para executar a conversão.If the ToString(Int32, Int32) method is called to create a string that will later be converted back to a number, a corresponding method that assumes a similar numeric representation should be called to perform the conversion. Esses métodos incluem Convert.ToInt32(String, Int32) e Int32.Parse(String, NumberStyles).Such methods include Convert.ToInt32(String, Int32) and Int32.Parse(String, NumberStyles).

Exemplos

O exemplo a seguir define uma classe NumberFormatInfo personalizada que define o sinal de subtração como a cadeia de caracteres "~" e o sinal de adição como a cadeia de caracteres "!".The following example defines a custom NumberFormatInfo class that defines its negative sign as the string "~" and its positive sign as the string "!". Em seguida, ele Convert.ToString(SByte, IFormatProvider) chama o método para converter cada elemento na matriz de bytes assinada em sua representação de cadeia de caracteres equivalente.It then calls the Convert.ToString(SByte, IFormatProvider) method to convert each element in signed byte array to its equivalent string representation. A conversão usa a cultura invariável, bem como o objeto NumberFormatInfo personalizado.The conversion uses the invariant culture as well as the custom NumberFormatInfo object.

sbyte[] numbers = { SByte.MinValue, -12, 17, SByte.MaxValue};
System.Globalization.NumberFormatInfo nfi = new System.Globalization.NumberFormatInfo();
nfi.NegativeSign = "~";
nfi.PositiveSign = "!";
foreach (sbyte number in numbers)

Se value for positivo e toBase não for 10, a cadeia de caracteres retornada usará a representação de entrada e magnitude.If value is positive and toBase is not 10, the returned string uses sign-and-magnitude representation. Se value for negativo e toBase não for 10, a cadeia de caracteres retornada usará a representação complementar de duas.If value is negative and toBase is not 10, the returned string uses two's complement representation. Isso significa que o bit de ordem superior do byte de ordem mais alta (bit 63) é interpretado como o bit de sinal.This means that the high-order bit of the highest-order byte (bit 63) is interpreted as the sign bit. Se o ToString(Int64, Int32) método for chamado para criar uma cadeia de caracteres que posteriormente será convertida de volta em um número, um método correspondente que assume uma representação numérica semelhante deve ser chamado para executar a conversão.If the ToString(Int64, Int32) method is called to create a string that will later be converted back to a number, a corresponding method that assumes a similar numeric representation should be called to perform the conversion. Esses métodos incluem Convert.ToInt64(String, Int32) e Int64.Parse(String, NumberStyles).Such methods include Convert.ToInt64(String, Int32) and Int64.Parse(String, NumberStyles).

Parâmetros

value
Object Object Object Object

Um objeto que fornece o valor a ser convertido ou null.An object that supplies the value to convert, or null.

provider
IFormatProvider IFormatProvider IFormatProvider IFormatProvider

Um objeto que fornece informações de formatação específicas de cultura.An object that supplies culture-specific formatting information.

Retornos

A representação de cadeia de caracteres de value, ou Empty se value for um objeto cujo valor é null.The string representation of value, or Empty if value is an object whose value is null. Se value for null, o método retornará null.If value is null, the method returns null.

Exemplos

Se o value parâmetro implementar a IConvertible interface, o método chamará IConvertible.ToString(IFormatProvider) a implementação valuede.If the value parameter implements the IConvertible interface, the method calls the IConvertible.ToString(IFormatProvider) implementation of value. Caso contrário, se value o parâmetro implementar IFormattable a interface, o método chamará sua IFormattable.ToString(String, IFormatProvider) implementação.Otherwise, if the value parameter implements the IFormattable interface, the method calls its IFormattable.ToString(String, IFormatProvider) implementation. Se value o implementar nenhuma interface, o método chamará o ToString() value método do parâmetro e provider o parâmetro será ignorado.If value implements neither interface, the method calls the value parameter's ToString() method, and the provider parameter is ignored.

O provider parâmetro será usado se o value parâmetro implementar a IConvertible interface IFormattable ou.The provider parameter is used if the value parameter implements the IConvertible or IFormattable interface. O uso mais comum do provider parâmetro é especificar informações específicas de cultura usadas na conversão de. valueThe most common use of the provider parameter is to specify culture-specific information used in the conversion of value. Por exemplo, se o value parâmetro for um número decimal negativo, o provider parâmetro poderá fornecer informações específicas de cultura sobre a notação usada para o sinal negativo e o separador decimal.For example, if the value parameter is a negative decimal number, the provider parameter can supply culture-specific information about the notation used for the negative sign and decimal separator. O segundo exemplo na próxima seção ilustra um provedor de formato que não fornece informações de formatação sensíveis à cultura.The second example in the next section illustrates a format provider that does not supply culture-sensitive formatting information.

Um objeto que fornece informações de formatação específicas de cultura.An object that supplies culture-specific formatting information.

Retornos

A representação da cadeia de caracteres de value.The string representation of value.

Exemplos

O exemplo a seguir define uma classe NumberFormatInfo personalizada que define o sinal de subtração como a cadeia de caracteres "~" e o sinal de adição como a cadeia de caracteres "!".The following example defines a custom NumberFormatInfo class that defines its negative sign as the string "~" and its positive sign as the string "!". Em seguida, ele ToString(UInt16, IFormatProvider) chama o método para converter um valor inteiro sem sinal de 16 bits em sua representação de cadeia de caracteres equivalente.It then calls the ToString(UInt16, IFormatProvider) method to convert a 16-bit unsigned integer value to its equivalent string representation. A conversão usa a cultura invariável e o objeto NumberFormatInfo personalizado.The conversion uses both the invariant culture and the custom NumberFormatInfo object. A saída indica que essas informações de formatação não são usadas porque, por padrão, o especificador de formato "G" não inclui um sinal positivo com valores positivos.The output indicates that this formatting information is not used, because by default the "G" format specifier does not include a positive sign with positive values.

Em seguida, ele ToString(UInt32, IFormatProvider) chama o método para converter um valor inteiro não assinado em sua representação de cadeia de caracteres equivalente.It then calls the ToString(UInt32, IFormatProvider) method to convert an unsigned integer value to its equivalent string representation. A conversão usa a cultura invariável e o objeto NumberFormatInfo personalizado.The conversion uses both the invariant culture and the custom NumberFormatInfo object. A saída indica que essas informações de formatação não são usadas porque, por padrão, o especificador de formato "G" não inclui um sinal positivo com valores positivos.The output indicates that this formatting information is not used, because by default the "G" format specifier does not include a positive sign with positive values.

uint number = UInt32.MaxValue;
System.Globalization.NumberFormatInfo nfi = new System.Globalization.NumberFormatInfo();
nfi.NegativeSign = "~";
nfi.PositiveSign = "!";

Console.WriteLine("{0,-8}  -->  {1,8}",
                  Convert.ToString(number, System.Globalization.CultureInfo.InvariantCulture),
                  Convert.ToString(number, nfi));
// The example displays the following output:
//       4294967295  -->  4294967295
Dim number As UInteger = UInt32.MaxValue
Dim nfi As New System.Globalization.NumberFormatInfo()
nfi.NegativeSign = "~"
nfi.PositiveSign = "!"

Se toBase não for igual a 10, a cadeia de caracteres retornada Convert.ToString(Byte, Int32) pelo método representará value somente por sua magnitude.If toBase does not equal 10, the string that is returned by the Convert.ToString(Byte, Int32) method represents value by its magnitude only. Se o método for chamado para criar uma cadeia de caracteres que posteriormente será convertida de volta em um número, um método correspondente que assume uma representação numérica somente de magnitude deve ser chamado para executar a conversão.If the method is called to create a string that will later be converted back to a number, a corresponding method that assumes a magnitude-only numeric representation should be called to perform the conversion. Esses métodos incluem Convert.ToByte(String, Int32) ou Byte.Parse(String, NumberStyles).Such methods include Convert.ToByte(String, Int32) or Byte.Parse(String, NumberStyles).

Retornos

value é retornado inalterado.value is returned unchanged.

Exemplos

O exemplo a seguir passa uma cadeia de ToString(String) caracteres para o método Object.ReferenceEquals e chama o método para confirmar que o método retorna a cadeia de caracteres original.The following example passes a string to the ToString(String) method and calls the Object.ReferenceEquals method to confirm that the method returns the original string. O exemplo também chama o String.IsInterned método para garantir que as duas cadeias de caracteres não sejam idênticas, pois a cadeia original é interna.The example also calls the String.IsInterned method to ensure that the two strings are not identical because the original string is interned.
