Modernizing double loops in C#?

Generate vectors with a generator:

public static IEnumerable<Vector2> ToAreaVectorSetByRadius(this int radius){
    Vector2 x1Vector= new (1, 0)
    Vector2 y1Vector= new (0,1)
    Vector2 theVector =  new Vector(-radius, -radius);
    for (int dx = -radius; dx < radius; dx++){
        for (int dy = -radius; dy <= radius; dy++){
             yield return theVector;
             theVector = theVector + y1Vector;
      }
      theVector = theVector + x1Vector;
    }
}

//{ ...
Dictionary<Vector2, object> theDictionary = new (){
  { new (){X=2, Y=3}, "what"},
  { new (){X=3, Y=3}, "nothing"}};

IEnumerable<Vector2> theVectorsByRadius = 5.ToAreaVectorSetByRadius();

var theNewSet = theVectors.AsParallel().Where(v => theDictionary.TryGetValue(v, out var item) && item is {}).ToArray();

Console.WriteLine(string.Join(',', theNewSet.AsEnumerable()));

// instead of mutating your object list, I made a separate collection. You can do with it as you wish.
//}

public static IEnumerable<Vector2> ToAreaVectorSetByRadius(this int radius){
    Vector2 x1Vector= new (1, 0)
    Vector2 y1Vector= new (0,1)
    Vector2 theVector =  new Vector(-radius, -radius);
    for (int dx = -radius; dx < radius; dx++){
        for (int dy = -radius; dy <= radius; dy++){
             yield return theVector;
             theVector = theVector + y1Vector;
      }
      theVector = theVector + x1Vector;
    }
}

//{ ...
Dictionary<Vector2, object> theDictionary = new (){
  { new (){X=2, Y=3}, "what"},
  { new (){X=3, Y=3}, "nothing"}};

IEnumerable<Vector2> theVectorsByRadius = 5.ToAreaVectorSetByRadius();

var theNewSet = theVectors.AsParallel().Where(v => theDictionary.TryGetValue(v, out var item) && item is {}).ToArray();

Console.WriteLine(string.Join(',', theNewSet.AsEnumerable()));

// instead of mutating your object list, I made a separate collection. You can do with it as you wish.
//}

There you go. Linq Golfing.

BlackJack method

switch(variableToCheck)
{
  case {Card1: "A", Card2:"F"} or {Card1: "F", Card2: "A"}: break;
  default: //check other scenarios...
    break;
}

switch(variableToCheck)
{
  case {Card1: "A", Card2:"F"} or {Card1: "F", Card2: "A"}: break;
  default: //check other scenarios...
    break;
}

could be

case Pattern<TypeArg> BlackJackCase { Card1: "A", Card2: "F" } or {Card1: "F", Card2: "A"};

switch(variableToCheck)
{
  case BlackJackCase: break;
  default : break;
}

case Pattern<TypeArg> BlackJackCase { Card1: "A", Card2: "F" } or {Card1: "F", Card2: "A"};

switch(variableToCheck)
{
  case BlackJackCase: break;
  default : break;
}

Great case for a feature release of variable pattern matches. If only 🥺

Imagine hitting enter, and if the end of the line lacks a semicolon, it deletes the line 💀

❔ Net 7 How to output one exe without dlls

I used chatgpt to create a bash script to pipe tar archives without persisting them on the filesystem, and then grabbed the artifact I wanted out of it. Maybe you could try that (I dont have the code available to me atm)

❔ Social media profiles hidden information?

Model.CouldBe(emailSource=>emailSource as emailSourceDTO);

Model.CouldBe(emailSource=>emailSource as emailSourceDTO);

Model.CouldBe<emailSourceDTO>();

Model.CouldBe<emailSourceDTO>();

Model.CouldBe(typeof(emailSourceDTO));

Model.CouldBe(typeof(emailSourceDTO));

❔ Social media profiles hidden information?

You could setup a pattern for your dto validation like:

Model.CouldBe(emailSource=>emailSource.tryGetValue(emailSourceKey, out var emailSourceObject) ? emailSourceObject as emailSourceDTO : default)
.CouldBe(addressSource...)
.CouldBe(infoSource...)

Model.CouldBe(emailSource=>emailSource.tryGetValue(emailSourceKey, out var emailSourceObject) ? emailSourceObject as emailSourceDTO : default)
.CouldBe(addressSource...)
.CouldBe(infoSource...)

Your parameter for the Func would be an IDictionary, or you might be able to use, as, to try casting it to your dto Make a special attribute for model validation, and voila
