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.

Exception Condition
IOException

An I/O error occurred.

If value is null, 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.

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.

public class Example
{
   public static void Main()
   {
      string[] lines = { "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();
      foreach (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();
      foreach (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.
