Exemples

L’exemple suivant illustre la Remove méthode.

using namespace System;
using namespace System::Text;
int main()
{
   String^ rule1 = "0----+----1----+----2----+----3----+----4---";
   String^ rule2 = "01234567890123456789012345678901234567890123";
   String^ str = "The quick brown fox jumps over the lazy dog.";
   StringBuilder^ sb = gcnew StringBuilder( str );
   Console::WriteLine();
   Console::WriteLine( "StringBuilder.Remove method" );
   Console::WriteLine();
   Console::WriteLine( "Original value:" );
   Console::WriteLine( rule1 );
   Console::WriteLine( rule2 );
   Console::WriteLine( "{0}", sb );
   Console::WriteLine();
   sb->Remove( 10, 6 ); // Remove "brown "
   Console::WriteLine( "New value:" );
   Console::WriteLine( rule1 );
   Console::WriteLine( rule2 );
   Console::WriteLine( "{0}", sb );
}

Remarques

La méthode actuelle supprime la plage de caractères spécifiée de l’instance actuelle. Les caractères à (startIndex + length) sont déplacés vers startIndex, et la valeur de chaîne de l’instance actuelle est raccourcie par length. La capacité de l’instance actuelle n’est pas affectée.

Notes

La Remove méthode modifie la valeur de l’instance actuelle StringBuilder et retourne cette instance. Il ne crée pas et ne retourne pas d’objet StringBuilder .
