Modifying list with linq

I'm trying to filter a list with linq, the problem is that when filtering a list with linq it only returns the result of the filter, and im looking for a way to modify the list rather than getting a result of the filter, because im doing it on a foreach.

Here is the foreach im doing:

foreach(Filtro f in filtros)
{
    if(f.Activo)
    {
        switch(f.TipoFiltro)
        {
            case TipoFiltro.nombre:
                jugadoresFiltrados.Where(j => j.Nombre.Contains(f.ContenidoFiltro));
                break;
            case TipoFiltro.equipo:
                jugadoresFiltrados.Where(j => j.EquipoJugador.Contains(f.ContenidoFiltro));
                break;
            case TipoFiltro.mundial:
                break;
        }
    }
}

This won't work because I'm not modifiying the jugadoresFiltrados list.

Where returns the filtered list, it doesn't change the collection:

Returns an IEnumerable that contains elements from the input sequence that satisfy the condition.

So you need to assign the filtered list back to the collection, for example:

jugadoresFiltrados = jugadoresFiltrados.Where(j => j.Nombre.Contains(f.ContenidoFiltro));

If jugadoresFiltrados is a List, you will need to call ToList() as well:

jugadoresFiltrados = jugadoresFiltrados.Where(j => j.Nombre.Contains(f.ContenidoFiltro)).ToList();
