Remarks

Esse método usa o recurso de formatação composta do .NET Framework para converter o valor de um objeto em sua representação de texto e inserir essa representação em uma cadeia de caracteres.This method uses the composite formatting feature of the .NET Framework to convert the value of an object to its text representation and embed that representation in a string. A cadeia de caracteres resultante é gravada no fluxo de saída.The resulting string is written to the output stream.

O parâmetro format consiste em zero ou mais execuções de texto combinadas com zero ou mais espaços reservados indexados, chamados de itens de formato, que correspondem a um objeto na lista de parâmetros desse método.The format parameter consists of zero or more runs of text intermixed with zero or more indexed placeholders, called format items, that correspond to an object in the parameter list of this method. O processo de formatação substitui cada item de formato pela representação de texto do valor do objeto correspondente.The formatting process replaces each format item with the text representation of the value of the corresponding object.

A sintaxe de um item de formato é {índice[ alinhamentode,] [:FormatString]}, que especifica um índice obrigatório, o comprimento opcional e o alinhamento do texto formatado e uma cadeia de caracteres opcional de formatos de especificador de formato que governam como o valor do objeto correspondente é formatado.The syntax of a format item is {index[,alignment][:formatString]}, which specifies a mandatory index, the optional length and alignment of the formatted text, and an optional string of format specifier characters that govern how the value of the corresponding object is formatted.

O .NET Framework fornece suporte extenso à formatação, que é descrito com mais detalhes nos tópicos de formatação a seguir.The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics.

Para obter mais informações sobre o terminador de linha, consulte a seção Comentários do método WriteLine que não usa parâmetros.For more information about the line terminator, see the Remarks section of the WriteLine method that takes no parameters.

Remarks

Esse método usa o recurso de formatação composta do .NET Framework para converter o valor de um objeto em sua representação de texto e inserir essa representação em uma cadeia de caracteres.This method uses the composite formatting feature of the .NET Framework to convert the value of an object to its text representation and embed that representation in a string. A cadeia de caracteres resultante é gravada no fluxo de saída.The resulting string is written to the output stream.

O parâmetro format consiste em zero ou mais execuções de texto combinadas com zero ou mais espaços reservados indexados, chamados de itens de formato, que correspondem a um objeto na lista de parâmetros desse método.The format parameter consists of zero or more runs of text intermixed with zero or more indexed placeholders, called format items, that correspond to an object in the parameter list of this method. O processo de formatação substitui cada item de formato pela representação de texto do valor do objeto correspondente.The formatting process replaces each format item with the text representation of the value of the corresponding object.

A sintaxe de um item de formato é {índice[ alinhamentode,] [:FormatString]}, que especifica um índice obrigatório, o comprimento opcional e o alinhamento do texto formatado e uma cadeia de caracteres opcional de formatos de especificador de formato que governam como o valor do objeto correspondente é formatado.The syntax of a format item is {index[,alignment][:formatString]}, which specifies a mandatory index, the optional length and alignment of the formatted text, and an optional string of format specifier characters that govern how the value of the corresponding object is formatted.

O .NET Framework fornece suporte extenso à formatação, que é descrito com mais detalhes nos tópicos de formatação a seguir.The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics.

Para obter mais informações sobre o terminador de linha, consulte a seção Comentários do método WriteLine que não usa parâmetros.For more information about the line terminator, see the Remarks section of the WriteLine method that takes no parameters.

Notes to Callers

Esse método não é chamado pelo C++ código.This method is not called by C++ code. O C++ compilador resolve chamadas para System. console. WriteLine que incluem uma cadeia de caracteres e uma lista de quatro ou mais parâmetros de objeto como uma chamada para WriteLine(String, Object, Object, Object, Object).The C++ compiler resolves calls to System.Console.WriteLine that include a string and a list of four or more object parameters as a call to WriteLine(String, Object, Object, Object, Object). Ele resolve as chamadas para System. console. WriteLine que incluem uma cadeia de caracteres e uma matriz de objeto como uma chamada para WriteLine(String, Object).It resolves calls to System.Console.WriteLine that include a string and an object array as a call to WriteLine(String, Object).

Examples

O exemplo a seguir chama o método WriteLine(String, Object) para exibir cinco valores de Boolean gerados aleatoriamente.The following example calls the WriteLine(String, Object) method to display five randomly generated Boolean values.

Random rnd = new Random();
// Generate five random Boolean values.
for (int ctr = 1; ctr <= 5; ctr++) {
   Boolean bln = Convert.ToBoolean(rnd.Next(0, 2));
   Console.WriteLine("True or False: {0}", bln);
}

// The example displays an output similar to the following:
//       True or False: False
//       True or False: True
//       True or False: False
//       True or False: False
//       True or False: True
Module Example
   Public Sub Main()
      Dim rnd As New Random()
      ' Generate five random Boolean values.
      For ctr As Integer = 1 To 5
         Dim bool As Boolean = Convert.ToBoolean(rnd.Next(0, 2))
         Console.WriteLine("True or False: {0}", bool)
      Next
   End Sub
End Module
' The example displays the following output:
'       True or False: False
'       True or False: True
'       True or False: False
'       True or False: False
'       True or False: True

O exemplo a seguir chama o método WriteLine(String, Object) para exibir a data atual.The following example calls the WriteLine(String, Object) method to display the current date. Observe que o item de formato no argumento format usa a cadeia de caracteres de formato padrão "D" e de hora para exibir a data no formato de data por extenso da cultura atual.Note that the format item in the format argument uses the "D" standard date and time format string to display the date in the long date format of the current culture.

using System;

public class Example
{
   public static void Main()
   {
      Console.WriteLine("Today's date: {0:D}", DateTime.Now);
   }
}
// The example displays output like the following:
//       Today's date: Monday, April 1, 2019
Module Example
   Public Sub Main()
      Console.WriteLine("Today's date: {0:D}", DateTime.Now)
   End Sub
End Module
' The example displays output like the following:
'       Today's date: Friday, April 1, 2016

Remarks

O terminador de linha padrão é uma cadeia de caracteres cujo valor é um retorno de carro seguido por uma alimentação de C#linha ("\r\n" no, ou vbCrLf em Visual Basic).The default line terminator is a string whose value is a carriage return followed by a line feed ("\r\n" in C#, or vbCrLf in Visual Basic). Você pode alterar o terminador de linha definindo a propriedade TextWriter.NewLine da propriedade Out como outra cadeia de caracteres.You can change the line terminator by setting the TextWriter.NewLine property of the Out property to another string. O exemplo fornece uma ilustração.The example provides an illustration.

Remarks

Esse método usa o recurso de formatação composta do .NET Framework para converter o valor de um objeto em sua representação de texto e inserir essa representação em uma cadeia de caracteres.This method uses the composite formatting feature of the .NET Framework to convert the value of an object to its text representation and embed that representation in a string. A cadeia de caracteres resultante é gravada no fluxo de saída.The resulting string is written to the output stream.

O parâmetro format consiste em zero ou mais execuções de texto combinadas com zero ou mais espaços reservados indexados, chamados de itens de formato, que correspondem a um objeto na lista de parâmetros desse método.The format parameter consists of zero or more runs of text intermixed with zero or more indexed placeholders, called format items, that correspond to an object in the parameter list of this method. O processo de formatação substitui cada item de formato pela representação de texto do valor do objeto correspondente.The formatting process replaces each format item with the text representation of the value of the corresponding object.

A sintaxe de um item de formato é {índice[ alinhamentode,] [:FormatString]}, que especifica um índice obrigatório, o comprimento opcional e o alinhamento do texto formatado e uma cadeia de caracteres opcional de formatos de especificador de formato que governam como o valor do objeto correspondente é formatado.The syntax of a format item is {index[,alignment][:formatString]}, which specifies a mandatory index, the optional length and alignment of the formatted text, and an optional string of format specifier characters that govern how the value of the corresponding object is formatted.

O .NET Framework fornece suporte extenso à formatação, que é descrito com mais detalhes nos tópicos de formatação a seguir.The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics.

WriteLine(Object)

Grava a representação de texto do objeto especificado, seguido do terminador de linha atual, no fluxo de saída padrão.Writes the text representation of the specified object, followed by the current line terminator, to the standard output stream.

public:
 static void WriteLine(System::Object ^ value);
public static void WriteLine (object value);
static member WriteLine : obj -> unit
Public Shared Sub WriteLine (value As Object)

Parameters

value
Object

O valor a ser gravado.The value to write.

Exceptions

Ocorreu um erro de E/S.An I/O error occurred.

Examples

O exemplo a seguir usa o método WriteLine(Object) para exibir cada valor em uma matriz de objeto para o console.The following example uses the WriteLine(Object) method to display each value in an object array to the console.

using namespace System;

void main()
{
   array<Object^>^ values = { true, 12.632, 17908, "stringValue",
                              'a', (Decimal) 16907.32 };
   for each (Object^ value in values)
      Console::WriteLine(value);
}
// The example displays the following output:
//    True
//    12.632
//    17908
//    stringValue
//    a
//    16907.32
Object[] values = { true, 12.632, 17908, "stringValue",
                           'a', 16907.32m };
foreach (var value in values)
   Console.WriteLine(value);

// The example displays the following output:
//    True
//    12.632
//    17908
//    stringValue
//    a
//    16907.32
Module Example
   Public Sub Main()
      Dim values() As Object = { True, 12.632, 17908, "stringValue",
                                 "a"c, 16907.32d }
      For Each value In values
         Console.WriteLine(value)
      Next                           
   End Sub
End Module
' The example displays the following output:
'    True
'    12.632
'    17908
'    stringValue
'    a
'    16907.32

Remarks

Se value for null, o terminador de linha será gravado.If value is null, only the line terminator is written. Caso contrário, o método de ToString de value é chamado para produzir sua representação de cadeia de caracteres e a cadeia de caracteres resultante é gravada no fluxo de saída padrão.Otherwise, the ToString method of value is called to produce its string representation, and the resulting string is written to the standard output stream.

Para obter mais informações sobre o terminador de linha, consulte a seção Comentários do método WriteLine que não usa parâmetros.For more information about the line terminator, see the Remarks section of the WriteLine method that takes no parameters.
