Easy HashCode and Equals override #105
Description
Proposition
An easy way to implement default HashCode and Equals method, similar to that implemented by anonymous types
Situation
If the HashCode and Equals are already implemented by the language in some situation, why I should reimplement it?
I got myself, doing this more than one time:
public class SomeThing
{
public decimal Tax { get; set; }
public decimal Comission { get; set; }
// Etc...
public override int GetHashCode()
{
return new
{
Tax,
Comission,
}.GetHashCode();
}
public override bool Equals(object obj)
{
var other = obj as SomeThing;
if (other == null)
return false;
return new { Tax, Comission }.Equals(new { other.Tax, other.Comission });
}
}Why not something like this:
[DefaultHashCode]
[DefaultEquals]
public class SomeThing
{
public decimal Tax { get; set; }
public decimal Comission { get; set; }
// Etc...
}Or maybe:
public class SomeThing
{
public decimal Tax { get; set; }
public decimal Comission { get; set; }
// Etc...
public override object GetStrucuralProperties()
{
return new { Tax, Comission };
}
}
