a.Equals(b) is the basic way to check if two elements are the same. But it is Obsolete!
For the case I want to use record, the equality is almost unusable.
|
/// <inheritdoc /> |
|
/// <summary>Indicates strict equality of two <see cref="Length"/> quantities, where both <see cref="Value" /> and <see cref="Unit" /> are exactly equal.</summary> |
|
[Obsolete("Use Equals(Length other, Length tolerance) instead, to check equality across units and to specify the max tolerance for rounding errors due to floating-point arithmetic when converting between units.")] |
|
public override bool Equals(object? obj) |
|
{ |
|
if (obj is null || !(obj is Length otherQuantity)) |
|
return false; |
|
|
|
return Equals(otherQuantity); |
|
} |
|
|
|
/// <inheritdoc /> |
|
/// <summary>Indicates strict equality of two <see cref="Length"/> quantities, where both <see cref="Value" /> and <see cref="Unit" /> are exactly equal.</summary> |
|
[Obsolete("Use Equals(Length other, Length tolerance) instead, to check equality across units and to specify the max tolerance for rounding errors due to floating-point arithmetic when converting between units.")] |
|
public bool Equals(Length other) |
|
{ |
|
return new { Value, Unit }.Equals(new { other.Value, other.Unit }); |
|
} |
Shall we add a static class like Global Tolerance Configurations to let it work like the Equals method with tolerance? That would make things ez.
|
/// <inheritdoc /> |
|
public bool Equals(Length other, Length tolerance) |
|
{ |
|
return UnitsNet.Comparison.Equals( |
|
referenceValue: this.Value, |
|
otherValue: other.As(this.Unit), |
|
tolerance: tolerance.As(this.Unit), |
|
comparisonType: ComparisonType.Absolute); |
|
} |
So it should look like this.
public bool Equals(Length other)
{
return Equals(other, GlobalToleranceConfigurations.Length);
}
