Console::WriteLine Method (String)

Writes the specified string value, followed by the current line terminator, to the standard output stream.

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

[HostProtectionAttribute(SecurityAction::LinkDemand, UI = true)]
public:
static void WriteLine(
	String^ value
)

Parameters

value
Type: System::String

The value to write.

ExceptionCondition
IOException

An I/O error occurred.

If value is nullptr, only the line terminator is written to the standard output stream.

For more information about the line terminator, see the Remarks section of the WriteLine() method.

NoteNote

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: UI. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

The example changes the line terminator from its default value of "\r\n" or vbCrLf to "\r\n\r\n" or vbCrLf + vbCrLf. It then calls the WriteLine() and WriteLine(String) methods to display output to the console.

using namespace System;

void main()
{
   array<String^>^ lines = gcnew array<String^> { "This is the first line.", 
                                                  "This is the second line." };
   // Output the lines using the default newline sequence.
   Console::WriteLine("With the default new line characters:");
   Console::WriteLine();
   for each (String^ line in lines)
      Console::WriteLine(line);

   Console::WriteLine();

   // Redefine the newline characters to double space.
   Console::Out->NewLine = "\r\n\r\n";
   // Output the lines using the new newline sequence.
   Console::WriteLine("With redefined new line characters:");
   Console::WriteLine();
   for each (String^ line in lines)
      Console::WriteLine(line);
}
// The example displays the following output: 
//       With the default new line characters: 
//        
//       This is the first line. 
//       This is the second line. 
//        
//       With redefined new line characters: 
//        
//        
//        
//       This is the first line. 
//        
//       This is the second line.
