Output code from 1 to n when c# n value is entered

C.Lynn's been speaking C# for 2 weeks. I'm listening to the company lecture. Instead of solving examples and giving assignments, I'm giving assignments and listening to explanations.

Even if I search the Internet, there are not many examples of c#, so I want to get help from masters.

You have to do your homework on your own to make the class meaningful.

Please check this example.

linq to try it. Just the way.

void Main()
{
    int n = 5;

    var r = from i in Enumerable.Range(1, n)
            select string.Concat(Enumerable.Repeat("*", i));

    foreach (var line in r) Console.WriteLine(line);
    Console.WriteLine();


    var r2 = from i in Enumerable.Range(1, n).Reverse()
             select string.Concat(Enumerable.Repeat("*", i));

    foreach (var line in r2) Console.WriteLine(line);
    Console.WriteLine();

    var r3 = from i in Enumerable.Range(1, n).Concat(Enumerable.Range(1, n - 1).Reverse())
             select string.Concat(Enumerable.Repeat("*", i));

    foreach (var line in r3) Console.WriteLine(line);
    Console.WriteLine();

    var r4 = from i in Enumerable.Range(1, n)
             select string.Concat(Enumerable.Range(1, i));

    foreach (var line in r4) Console.WriteLine(line);
}
