Commenti

Nota

Questa API non è conforme a CLS.This API is not CLS-compliant. L'alternativa conforme a CLS è Console.Write(String, Object[]).The CLS-compliant alternative is Console.Write(String, Object[]). I C# compilatori e Visual Basic risolvono automaticamente una chiamata a questo metodo come chiamata Console.Write(String, Object[])a.The C# and Visual Basic compilers automatically resolve a call to this method as a call to Console.Write(String, Object[]).

Questo metodo usa la funzionalità di formattazione composita del .NET Framework per convertire il valore di un oggetto nella relativa rappresentazione testuale e incorporare tale rappresentazione in una stringa.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. La stringa risultante viene scritta nel flusso di output.The resulting string is written to the output stream.

Il format parametro è costituito da zero o più esecuzioni di testo combinate con zero o più segnaposto indicizzati, denominati elementi di formato, che corrispondono a un oggetto nell'elenco di parametri di questo metodo.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. Il processo di formattazione sostituisce ogni elemento di formato con la rappresentazione testuale del valore dell'oggetto corrispondente.The formatting process replaces each format item with the text representation of the value of the corresponding object.

La sintassi di un elemento di formato {è index[,Alignment]:[FormatString]}, che specifica un indice obbligatorio, la lunghezza e l'allineamento facoltativi del testo formattato e un stringa facoltativa di caratteri identificatori di formato che determinano la formattazione del valore dell'oggetto corrispondente.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.

Il .NET Framework fornisce un supporto completo per la formattazione, descritto più dettagliatamente negli argomenti seguenti sulla formattazione.The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics.

Note per i chiamanti

Questo metodo è contrassegnato con la vararg parola chiave, il che significa che supporta un numero variabile di parametri.This method is marked with the vararg keyword, which means that it supports a variable number of parameters. Il metodo può essere chiamato dall'oggetto C++visivo, ma non può essere chiamato C# da o Visual Basic codice.The method can be called from Visual C++, but it cannot be called from C# or Visual Basic code. I C# compilatori e Visual Basic risolvono Write(String, Object, Object, Object, Object) le chiamate a Write(String, Object[])come chiamate a.The C# and Visual Basic compilers resolve calls to Write(String, Object, Object, Object, Object) as calls to Write(String, Object[]).

Commenti

Questo metodo usa la funzionalità di formattazione composita del .NET Framework per convertire il valore di un oggetto nella relativa rappresentazione testuale e incorporare tale rappresentazione in una stringa.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. La stringa risultante viene scritta nel flusso di output.The resulting string is written to the output stream.

Il format parametro è costituito da zero o più esecuzioni di testo combinate con zero o più segnaposto indicizzati, denominati elementi di formato, che corrispondono a un oggetto nell'elenco di parametri di questo metodo.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. Il processo di formattazione sostituisce ogni elemento di formato con la rappresentazione testuale del valore dell'oggetto corrispondente.The formatting process replaces each format item with the text representation of the value of the corresponding object.

La sintassi di un elemento di formato {è index[,Alignment]:[FormatString]}, che specifica un indice obbligatorio, la lunghezza e l'allineamento facoltativi del testo formattato e un stringa facoltativa di caratteri identificatori di formato che determinano la formattazione del valore dell'oggetto corrispondente.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.

Il .NET Framework fornisce un supporto completo per la formattazione, descritto più dettagliatamente negli argomenti seguenti sulla formattazione.The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics.

Commenti

Questo metodo usa la funzionalità di formattazione composita del .NET Framework per convertire il valore di un oggetto nella relativa rappresentazione testuale e incorporare tale rappresentazione in una stringa.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. La stringa risultante viene scritta nel flusso di output.The resulting string is written to the output stream.

Il format parametro è costituito da zero o più esecuzioni di testo combinate con zero o più segnaposto indicizzati, denominati elementi di formato, che corrispondono a un oggetto nell'elenco di parametri di questo metodo.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. Il processo di formattazione sostituisce ogni elemento di formato con la rappresentazione testuale del valore dell'oggetto corrispondente.The formatting process replaces each format item with the text representation of the value of the corresponding object.

La sintassi di un elemento di formato {è index[,Alignment]:[FormatString]}, che specifica un indice obbligatorio, la lunghezza e l'allineamento facoltativi del testo formattato e un stringa facoltativa di caratteri identificatori di formato che determinano la formattazione del valore dell'oggetto corrispondente.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.

Il .NET Framework fornisce un supporto completo per la formattazione, descritto più dettagliatamente negli argomenti seguenti sulla formattazione.The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics.

Esempi

Nell'esempio seguente viene definita Person una classe con una serie di proprietà che forniscono informazioni su una persona.The following example defines a Person class with a number of properties that provide information about a person. Il GetDescription metodo restituisce una matrice che contiene tutti i valori di proprietà tranne uno.Its GetDescription method returns an array that contains all of the property values except one. Nell'esempio viene quindi utilizzata la matrice restituita GetDescription dal metodo per visualizzare i valori dell'oggetto Person.The example then uses the array returned by the GetDescription method to display the values of the Person object.

using System;

public class Person
{
   public String Name { get; set; }
   public DateTime BirthDate  { get; set; }
   public Double Height { get; set; }
   public Double Weight { get; set; }
   public Char Gender { get; set; }
   public String Remarks { get; set; }

                              BirthDate = new DateTime(1992, 5, 10), 
                              Height = 73.5, Weight = 207 };
      p1.Remarks = "Client since 1/3/2012";
      Console.Write("{0}: {1}, born {4:d}  Height {2} inches, Weight {3} lbs  ",

                                    .Height = 73.5, .Weight = 207 }
      p1.Remarks = "Client since 1/3/2012"
      Console.Write("{0}: {1}, born {4:d}  Height {2} inches, Weight {3} lbs  ", 
                    p1.GetDescription())
      If String.IsNullOrEmpty(p1.Remarks) Then

End Module
' The example displays the following output:
'   John: M, born 5/10/1992  Height 73.5 inches, Weight 207 lbs  Remarks: Client since 1/3/2012

Si noti che nell'esempio viene Write(String, Object[]) chiamato il metodo anziché WriteLine(String, Object[]) il metodo perché tenta di Person.Remarks visualizzare il valore della proprietà nella stessa riga.Note that the example calls the Write(String, Object[]) method rather than the WriteLine(String, Object[]) method because it attempts to display the value of the Person.Remarks property on the same line. A tale scopo, esamina il valore delle CursorLeft proprietà e WindowWidth per determinare se è disponibile spazio sufficiente per il remark.To do this, it examines the value of the CursorLeft and WindowWidth properties to determine whether there is enough space for the remark to fit. Se è presente, viene visualizzata la riga.If there is, it displays the line. In caso contrario, viene scritta una riga, viene rientrato tre spazi e viene visualizzato il segno di spunta.If not, it writes a line, indents three spaces, and displays the remark.

L'esempio seguente è identico al primo, ad eccezione del fatto che fornisce un elenco di cinque elementi arg come argomento anziché una matrice di parametri.The following example is identical to the first, except that it supplies a five-item list as the arg argument instead of a parameter array.

Questo metodo usa la funzionalità di formattazione composita del .NET Framework per convertire il valore di un oggetto nella relativa rappresentazione testuale e incorporare tale rappresentazione in una stringa.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. La stringa risultante viene scritta nel flusso di output.The resulting string is written to the output stream.

Il format parametro è costituito da zero o più esecuzioni di testo combinate con zero o più segnaposto indicizzati, denominati elementi di formato, che corrispondono a un oggetto nell'elenco di parametri di questo metodo.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. Il processo di formattazione sostituisce ogni elemento di formato con la rappresentazione testuale del valore dell'oggetto corrispondente.The formatting process replaces each format item with the text representation of the value of the corresponding object.

La sintassi di un elemento di formato {è index[,Alignment]:[FormatString]}, che specifica un indice obbligatorio, la lunghezza e l'allineamento facoltativi del testo formattato e un stringa facoltativa di caratteri identificatori di formato che determinano la formattazione del valore dell'oggetto corrispondente.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.

Il .NET Framework fornisce un supporto completo per la formattazione, descritto più dettagliatamente negli argomenti seguenti sulla formattazione.The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics.

Se value ènull, non viene scritto alcun elemento e non viene generata alcuna eccezione.If value is null, nothing is written and no exception is thrown. In caso contrario ToString , il value metodo di viene chiamato per produrre la relativa rappresentazione di stringa e la stringa risultante viene scritta nel flusso di output standard.Otherwise, the ToString method of value is called to produce its string representation, and the resulting string is written to the standard output stream.
