its only writing the same random string, how can i make it do different ones?

you generate one random string, then you print it 1000 times. you don't actually generate a new one each time if you want to do that, stick your code in a method, or inline the code in your loop.

any examples of that?

public static string GetRandomString(int length = 20)
{
    const string alphabet = "abcdefghjkmnpqrstuvwxyz23456789";
    var sb = new StringBuilder();
    while (sb.Length < length)
    {
        sb.Append(alphabet[Random.Shared.Next(alphabet.Length)]);
    }

    return sb.ToString();
}

public static string GetRandomString(int length = 20)
{
    const string alphabet = "abcdefghjkmnpqrstuvwxyz23456789";
    var sb = new StringBuilder();
    while (sb.Length < length)
    {
        sb.Append(alphabet[Random.Shared.Next(alphabet.Length)]);
    }

    return sb.ToString();
}

this method will generate a new string each time its called

thanks

            Random res = new Random();

            String str = "abcdefghijklmnopqrstuvwxyz0123456789";
            int size = 32;


            String randomstring = "";

            for (int i = 0; i < size; i++)
            {

                // Selecting a index randomly
                int x = res.Next(str.Length);


                randomstring = randomstring + str[x];
            }
            int b = 0;
            while (b < 1000)
            {
                int milliseconds = 1;
                Thread.Sleep(milliseconds);
                Console.WriteLine(randomstring);
                b++;
            }

            Random res = new Random();

            String str = "abcdefghijklmnopqrstuvwxyz0123456789";
            int size = 32;


            String randomstring = "";

            for (int i = 0; i < size; i++)
            {

                // Selecting a index randomly
                int x = res.Next(str.Length);


                randomstring = randomstring + str[x];
            }
            int b = 0;
            while (b < 1000)
            {
                int milliseconds = 1;
                Thread.Sleep(milliseconds);
                Console.WriteLine(randomstring);
                b++;
            }

How would i use this into my code?

ah, your code is a top level statements program replace your entire code with this

public static class Program
{
    public static void Main()
    {
        for (int b = 0; b < 1000; b++)
        {
            var randomString = GetRandomString();
            int milliseconds = 1;
            Thread.Sleep(milliseconds);
            Console.WriteLine(randomString);
        }
    }

    public static string GetRandomString(int length = 20)
    {
        const string alphabet = "abcdefghjkmnpqrstuvwxyz23456789";
        var sb = new StringBuilder();
        while (sb.Length < length)
        {
            sb.Append(alphabet[Random.Shared.Next(alphabet.Length)]);
        }

        return sb.ToString();
    }
}

public static class Program
{
    public static void Main()
    {
        for (int b = 0; b < 1000; b++)
        {
            var randomString = GetRandomString();
            int milliseconds = 1;
            Thread.Sleep(milliseconds);
            Console.WriteLine(randomString);
        }
    }

    public static string GetRandomString(int length = 20)
    {
        const string alphabet = "abcdefghjkmnpqrstuvwxyz23456789";
        var sb = new StringBuilder();
        while (sb.Length < length)
        {
            sb.Append(alphabet[Random.Shared.Next(alphabet.Length)]);
        }

        return sb.ToString();
    }
}
