All other properties (`Predicate`, `ResponseWriter` and `AllowCachingResponses`) have a setter but `ResultStatusCodes` doesn't.
Without a setter, reusing the same status to http status code mapping is impossible and leads to duplicate code that looks like this:
```csharp
private static void ConfigureHealthChecks(IApplicationBuilder app, HealthCheckServiceOptions options)
{
app.UseHealthChecks("/health", new HealthCheckOptions
{
ResultStatusCodes =
{
[HealthStatus.Healthy] = StatusCodes.Status200OK,
[HealthStatus.Degraded] = StatusCodes.Status400BadRequest,
[HealthStatus.Unhealthy] = StatusCodes.Status503ServiceUnavailable
}
});
foreach (var name in options.Registrations.Select(e => e.Name))
{
app.UseHealthChecks($"/health/{name}", new HealthCheckOptions
{
Predicate = registration => registration.Name == name,
ResultStatusCodes =
{
[HealthStatus.Healthy] = StatusCodes.Status200OK,
[HealthStatus.Degraded] = StatusCodes.Status400BadRequest,
[HealthStatus.Unhealthy] = StatusCodes.Status503ServiceUnavailable
}
});
}
}
```
With a setter, this code could be rewritten in a *don't repeat yourself* (DRY) way:
```csharp
private static void ConfigureHealthChecks(IApplicationBuilder app, HealthCheckServiceOptions options)
{
var resultStatusCodes = new Dictionary<HealthStatus, int>
{
[HealthStatus.Healthy] = StatusCodes.Status200OK,
[HealthStatus.Degraded] = StatusCodes.Status400BadRequest,
[HealthStatus.Unhealthy] = StatusCodes.Status503ServiceUnavailable
};
app.UseHealthChecks("/health", new HealthCheckOptions
{
ResultStatusCodes = resultStatusCodes
});
foreach (var name in options.Registrations.Select(e => e.Name))
{
app.UseHealthChecks($"/health/{name}", new HealthCheckOptions
{
Predicate = registration => registration.Name == name,
ResultStatusCodes = resultStatusCodes
});
}
}
