Customization

While most of the generated code can't be modified, you can customize some methods.

ToString()

Override ToString() manually, so the source generator will not emit a default implementation for it:

csharp

[StrongType<string>]
public sealed partial class Password
{
    public override string ToString() => "secret";
}

csharp

var password = Password.From("123456");
Console.WriteLine(password); // prints "secret"

TIP

You can also use the Quick Actions → Generate ToString().

[StrongType<string>]

public sealed partial class Password

{

Equality

Implement the partial Equals(T) method and override GetHashCode() manually, so the source generator will not emit a default implementation for those members:

csharp

[StrongType<string>]
public sealed partial class Currency
{
    public partial bool Equals(Currency? other) =>
        other is not null &&
        string.Equals(_value, other._value, StringComparison.OrdinalIgnoreCase);

    public override int GetHashCode() =>
        _value.GetHashCode(StringComparison.OrdinalIgnoreCase);
}

csharp

Currency.From("USD") == Currency.From("usd") // true

While you can implement the two methods separately, it's better to implement them both.

TIP

You can also use the Quick Actions → Generate Equals(T) and GetHashCode().
