how to pick a value in order from 1 to 10-CodePudding

am working with C# and Selenium and I need to send keys into a text field it would need to pick a name (the names I provide into a textbox) and then pick then send the first one (with send keys) after its done with the first one it would move to the second and so on. I have done this so far (but this would randomly pick a name and not in a order way from first to last)

var random = new Random();

//this is the textbox in which I place the "names"\\
        var Names = question1.Text.Split();

        int index = random.Next(Names.Length);

        string randomName = Names[index];`

this would just pick a random value I place into a textbox so I will need that but the issue with this is if am sending lets say 100 names after 25/50 the names would just start to be duplicates which led to an error so thats why I need it to select the names in order.

I think you can add all the names in Hashset and then using for loop you can pick names one by one

It looks like you need to use the shuffle algorithm first and then create a queue of shuffled names:

var shuffledNames = question1.Text.Split().OrderBy(_ => Guid.NewGuid());
var queueOfShuffledNames = new Queue<string>(shuffledNames);
        
Console.WriteLine($"Queue of shuffled names: {string.Join(", ", queueOfShuffledNames)}");
Console.WriteLine($"Selected name: {queueOfShuffledNames.Dequeue()}");
Console.WriteLine($"Queue of shuffled names: {string.Join(", ", queueOfShuffledNames)}");

If you need to remove duplication from the original collection and limit the number of items in the queue, create the shuffledNames this way:

var shuffledNames = question1.Text.Split()
    .OrderBy(_ => Guid.NewGuid())
    .Distinct()
    .Take(10);
