ID: csharp-best-practices/base-equals
Language: C#
Severity: Error
Category: Best Practices
Using base.Equals
can be dangerous when the base is not an object
because the new base class can override Equals
, leading to unexpected behavior. This rule prevents the use of base.Equals
in a class where the base is not an object
.
class NonCompliant : Compliant
{
private int bar;
public override bool Equals(object other)
{
bool eq1;
eq1 = base.Equals(other);
var eq2 = base.Equals(other);
if (base.Equals(other))
{
return true;
}
return this.bar == ((NonCompliant)other).bar;
}
}
class Compliant
{
private int foo;
public override bool Equals(object other)
{
if (base.Equals(other))
{
return true;
}
return this.foo == ((Compliant)other).foo;
}
}
class Compliant
{
private int foo;
public override bool Equals(object other)
{
if (base.Equals(other))
{
return true;
}
return this.foo == ((Compliant)other).foo;
}
}
