IEqualityComparer for class with many properties

Question

Hi all,

which is the best implementation for IEqualityComparer for this class ??

The entity has 7 properties.

Thanks in advanced.

[Serializable()]
    public class ServidorSeleccionadoDto
    {
        [XmlAttribute()]
        public int Id { get; set; }

        [XmlAttribute()]
        public string Nombre { get; set; }

        [XmlAttribute()]
        public string IP { get; set; }

        [XmlAttribute()]
        public string Entorno { get; set; }

        [XmlAttribute()] // [XmlIgnore()]
        public string Habilitado { get; set; }

        [XmlAttribute()]
        public string Tipo { get; set; }

        [XmlAttribute()]
        public int IdGrupo { get; set; }
    }

It looks like your object has an ID field. If this is unique to each object then you would only need to compare on that property.

public Boolean Equals(ServidorSeleccionadoDto obj)
{
   return this.ID == obj.ID;
}

Note: This would only work if ID is unique.

UPDATE ---

If the ID property is not unique you will need to compare all your objects properties.

public Boolean Equals(ServidorSeleccionadoDto obj)
{
    return this.ID == obj.ID && 
           this.Nombre.Equals(obj.Nombre) && 
           ... etc
}
