Importante
Parte de la información hace referencia a la versión preliminar del producto, que puede haberse modificado sustancialmente antes de lanzar la versión definitiva. Microsoft no otorga ninguna garantía, explícita o implícita, con respecto a la información proporcionada aquí.
Quita de la instancia el intervalo de caracteres especificado.
public:
System::Text::StringBuilder ^ Remove(int startIndex, int length);public System.Text.StringBuilder Remove (int startIndex, int length);member this.Remove : int * int -> System.Text.StringBuilderPublic Function Remove (startIndex As Integer, length As Integer) As StringBuilder- startIndex
- Int32
Posición de base cero en esta instancia donde comienza la eliminación.
- length
- Int32
Número de caracteres que se van a quitar.
Referencia a la instancia después de que se complete la operación de eliminación.
Si startIndex o length es menor que cero o startIndex + length es mayor que la longitud de esta instancia.
En el siguiente ejemplo se muestra el Remove método.
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 );
}

El método actual quita el intervalo de caracteres especificado de la instancia actual. Los caracteres de ( ) se mueven a y el valor de cadena startIndex + length de la instancia actual startIndex se abrevia mediante length . La capacidad de la instancia actual no se ven afectadas.
Nota
El Remove método modifica el valor de la instancia actual y devuelve esa StringBuilder instancia. No crea ni devuelve un objeto StringBuilder nuevo.
