Beispiele

In diesem Beispiel wird die CursorVisible -Eigenschaft veranschaulicht. Das Beispiel macht den Cursor sichtbar, wenn die erste Spalte der Eingabe ein "+"-Zeichen oder unsichtbar ist, wenn die Eingabe ein "-" Zeichen ist.

// This example demonstrates the Console.CursorVisible property.
using namespace System;

int main()
{
   String^ m1 = "\nThe cursor is {0}.\nType any text then press Enter. "
   "Type '+' in the first column to show \n"
   "the cursor, '-' to hide the cursor, "
   "or lowercase 'x' to quit:";
   String^ s;
   bool saveCursorVisibile;
   int saveCursorSize;
   
   //
   Console::CursorVisible = true; // Initialize the cursor to visible.
   saveCursorVisibile = Console::CursorVisible;
   saveCursorSize = Console::CursorSize;
   Console::CursorSize = 100; // Emphasize the cursor.
   for ( ; ;  )
   {
      Console::WriteLine( m1, ((Console::CursorVisible == true) ? (String^)"VISIBLE" : "HIDDEN") );
      s = Console::ReadLine();
      if ( String::IsNullOrEmpty( s ) == false )
            if ( s[ 0 ] == '+' )
            Console::CursorVisible = true;
      else
      if ( s[ 0 ] == '-' )
            Console::CursorVisible = false;
      else
      if ( s[ 0 ] == 'x' )
            break;

   }
   Console::CursorVisible = saveCursorVisibile;
   Console::CursorSize = saveCursorSize;
}
