Console::WriteLine Method (UInt32)

Writes the text representation of the specified 32-bit unsigned integer value, followed by the current line terminator, to the standard output stream.

This API is not CLS-compliant. 

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

[HostProtectionAttribute(SecurityAction::LinkDemand, UI = true)]
static void WriteLine(
	unsigned int value


Type: System::UInt32

The value to write.


An I/O error occurred.


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 text representation of value is produced by calling the UInt32::ToString method.

For more information about the line terminator, see the Remarks section of the WriteLine method that takes no parameters.

The following code example illustrates the use of the WriteLine method.

// System.Console.WriteLine 
using namespace System;
int main()
   array<String^>^args = Environment::GetCommandLineArgs();
   const double tipRate = 0.18;
   double billTotal;
   if ( args->Length != 2 )
      Console::WriteLine( "usage: TIPCALC total" );
      return 1;
         billTotal = Double::Parse( args[ 1 ] );
      catch ( FormatException^ ) 
         Console::WriteLine( "usage: TIPCALC total" );
         return 1;

      double tip = billTotal * tipRate;
      Console::WriteLine( "Bill total:\t{0,8:c}", billTotal );
      Console::WriteLine( "Tip total/rate:\t{0,8:c} ({1:p1})", tip, tipRate );
      Console::WriteLine( ((String^)"")->PadRight( 24, '-' ) );
      Console::WriteLine( "Grand total:\t{0,8:c}", billTotal + tip );
      return 0;

Example Output:

Bill total:       $52.23
Tip total/rate:    $9.40 (18.0 %)
Grand total:      $61.63
