because i can only call it via the object

not the class

if i make it static?

ye

ا

ا

احمدOP•10/22/23, 10:46 PM

{key, value,
... }

H

Hazel 🌊💃•10/22/23, 10:46 PM

You need to iterate over the elements and print each one like:

Console.WriteLine($"{item.Key}: {item.Value}");

Console.WriteLine($"{item.Key}: {item.Value}");

Console.WriteLine($"{item.Key}: {item.Value}");

Console.WriteLine($"{item.Key}: {item.Value}");

ا

احمدOP•10/22/23, 10:49 PM

hmm

ا

احمدOP•10/22/23, 10:49 PM

i'd need to iterate a certain number of times too

ا

احمدOP•10/22/23, 10:49 PM

so i got a question

ا

احمدOP•10/22/23, 10:50 PM

dict = {key, value [0]
key,value [1]
}

ا

احمدOP•10/22/23, 10:50 PM

does the first pair count as 0

ااحمد i'd need to iterate a certain number of times too

H

Hazel 🌊💃•10/22/23, 10:50 PM

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/statements/iteration-statements

Iteration statements -for, foreach, do, and while - C#

C# iteration statements (for, foreach, do, and while) repeatedly execute a block of code. You use those statements to create loops or iterate through a collection.

ااحمد does the first pair count as 0

C# is a zero-based language, yes.
