Decrementing a sentence

[Barend]

Hi, I have a problem with decrementing a sentence in C#, something like:
This is a sentence
This is a sentenc
This is a senten
This is a sente
This is a sent
... I have no idea how to do it, I have done a diamond etc, which basically just goes :

class Program
    {
        static void Main(string[] args)
        {
           int F = 20;
            int Q = 0;
            int E = 10;
            int A = 0;
            for (int C = 0; C <= 10; C++)
            {
                for (int D = 0; D <= E; D++)
                {
                    Console.Write(" ");
                }
                E = E - 1;
                    for (int B = 0; B <= A; B++)
                    {
                        Console.Write("*");
                    }
                A = A + 2;
                Console.WriteLine();
            }
            for (int R = 0; R <= 10; R++)
            {
                for (int P = 0; P<= Q; P++)
                {
                    Console.Write(" ");
                }
                Q = Q + 1;
                for (int G = 0; G <= F; G++)
                {
                    Console.Write("*");
                }
                F = F - 2;
                Console.WriteLine();
            }
 
 
 
                Console.ReadLine();
        }
    }
}

So I thought it might be around the same lines as this, but I cant get anything to work... I am new to C# so trying to figure these things out :/

Why dont we start with the code you've tried. Sometimes a fresh set of eyes can make a difference.

Ok well I have gone and kind of messed it up now by trying a char array, so this is the coding I have now 0_O

class Program
{
static void Main(string[] args)
{
char[] sin = "This is a sentence".ToCha rArray();

for(int i = sin.Length; i >= 0; --i)
{
Console.Write(s in[i]);
}
}
}
}

To simply take of 1 character at a time, you can use the Substring function which creates a new string from your initial string, but in this case you can specify an index. If you put this in a loop and subtract 1 character at a time, I think you get what you want.

This code did it for me.

        static void Main(string[] args)
        {
            string line = "This is my sentence";
 
            Console.WriteLine(line);
 
            // While the line still has characters in it, loop
            while (line.Length != 0)
            {
                // Substring from the start till the end minus 1 character
                line = line.Substring(0, (line.Length - 1));
 
                // Write the line
                Console.WriteLine(line);
            }
 
            // Hold before closing window
            Console.Read();
        }
 

Sometimes things may be less complicated as it seems.
