Use Case

Pseudo code:

output = "some@kind@of@weird@input".split('@')[0];

A couple possible responses you might have to seeing this kind of code a lot in the codebase you're working on:

public sealed class PaginatedResults<T>
{
    public required IReadOnlyList<T> Results { get; init; }
    public required int Page { get; init; }
    public required int PageSize { get; init; }
    public required int TotalCount { get; init; }

    public int TotalPages => (int)Math.Ceiling(TotalCount / (double)PageSize);
}

// change the next few lines to find your benchmarks using whatever logic you prefer.
const string BenchmarksNamespace = "YourBenchmarkNamespaceHere.Benchmarks";

var allBenchmarks = Assembly.GetExecutingAssembly()
    .GetTypes()
    .Where(t => t is { Namespace: BenchmarksNamespace, IsClass: true })

Creating an App Service w/ Key Vault & Application Insights

1. Create your App Service, Key Vault, and Application Insights

   1. Copy the Key Vault's "Vault URI" for later
   2. Copy the Application Insights' "Connection String" for later

2. In the App Service's "Identity", turn the "System assigned" "Status" to "On"

3. In the App Service's "Configuration", create a "New application setting" with value "KeyVaultURI", and value of the "Vault URI" you copied in step 1

I translated the following methods from Java, for use in C#, over a year ago (sometime in early 2022, or late 2021). Maybe there's better versions of the same elsewhere; I dunno. If this is the best that you - o weary traveller of the internet - could find, then I hope you find them useful for your purposes.

EncodeFilterValue

You know SQL injection attacks? Well, there's LDAP injection attacks, too.

The following method escapes values which you're tossing into LDAP search strings.
