Write Method (String, Object, Object, Object, Object, ...)

Console.Write Method (String, Object, Object, Object, Object)


Writes the text representation of the specified objects and variable-length parameter list to the standard output stream using the specified format information.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

C# does not support methods that use variable length arguments (varargs).\nThe compiler automatically resolves calls to this method to the same method that uses a\n parameter array.


Type: System.String

A composite format string (see Remarks).

Type: System.Object

The first object to write using format.

Type: System.Object

The second object to write using format.

Type: System.Object

The third object to write using format.

Type: System.Object

The fourth object to write using format.

A comma-delimited list of one or more additional objects to write using format.

Exception Condition

An I/O error occurred.


format is null.


The format specification in format is invalid.

This method uses the of the .NET Framework to convert the value of an object to its text representation and embed that representation in a string. The resulting string is written to the output stream.

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. The formatting process replaces each format item with the text representation of the value of the corresponding object.

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.

The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics.

Notes to Callers:

This method is marked with the vararg keyword, which means that it supports a variable number of parameters. The method can be called from Visual C++, but it cannot be called from C# or Visual Basic code. The C# and Visual Basic compilers resolve calls to Write(String, Object, Object, Object, Object) as calls to Write(String, Object[]).

The following example illustrates the use of variable parameters with the Write(String, Object, Object, Object, Object) method. The method is called with a composite format string and five format items.

using namespace System;

//void main(array<System::String ^> ^args)
void main()
   DateTime dateRecorded(2009, 6, 15);
   DateTime startTime(1, 1, 1, 0, 30, 0);
   TimeSpan interval(12, 0, 0);

   Double temperature1 = 52.8;
   Double temperature2 = 63.5;

   Console::Write("Date: {0:d}:\n   Temperature at {1:t}: {2}\n   Temperature at {3:t}: {4}\n", 
                  dateRecorded, startTime, temperature1, 
                  startTime.Add(interval), temperature2);
// The example displays the following output:
//      Date: 6/15/2009:
//         Temperature at 12:30 AM: 52.8
//         Temperature at 12:30 PM: 63.5
