如何将加性噪声添加到数字序列中，C#？

Question

我是 C# 的初学者。 如何将加性噪声添加到数字序列中？ 例如，我想将 Noise(3,2,1) 添加到这个序列中：

1:1
2:1
3:1
4:1
5:2
6:1
6:2
6:60
7:1
8:1
9:2
10:1

预期结果如下，噪声会随机添加。

1:1
2:1
3:1
4:1**,3**
5:2
6:1
6:2
6:60**,2**
7:1
8:1
9:2**,1**
10:1

以下是使用通用列表完成任务的一种方法。泛型列表类型在概念上类似于数组，但包含额外的功能，让生活更轻松。

否则，您可以使用简单的数组来获得相同的结果。

        //using System.Collections.Generic;
        //using System.Linq;
        Console.Clear();
        List<String> Clean = new List<string>() { "1:1", "2:1", "3:1", "4:1", "5:2", "6:1", "6:2", "6:60", "7:1", "8:1", "9:2", "10:10" };
        for (int i = 0; i < 3; i++)
        {
            Random rnd = new Random(DateTime.Now.Millisecond);
            int index = rnd.Next(0, Clean.Count);
            if (Clean[index].Contains("*"))
            {//Already has noise.
                i--;
            }
            else
            {//Make some noise.
                Clean[index] = Clean[index] + "**" + i.ToString() + "* *";
            }
        }
        Clean.ForEach(var => Console.WriteLine(var));
        Console.WriteLine();
        Console.ReadLine();

        using (OpenFileDialog ofd = new OpenFileDialog())
        {
            if (ofd.ShowDialog() != DialogResult.OK)
                return;

            string fn = ofd.FileName;


            string[] lines = File.ReadAllLines(fn);

            txtData.Text = "";

            List<string> Clean = new List<string>(lines);
            for (int i = 0; i < 3; i++)
            {
                Random rnd = new Random(DateTime.Now.Millisecond);
                int index = rnd.Next(0, Clean.Count);
                if (Clean[index].Contains(","))
                {//Already has noise.
                    i--;
                }
                else
                {//Make some noise.
                    Clean[index] = Clean[index] + "," + i.ToString();
                }
            }
            //Clean.ForEach(var => Console.WriteLine(var));
            // Console.WriteLine();
            // Console.ReadLine();
            for (int i = 0; i < Clean.Count; i++)
            {
                txtData.Text += Clean[i] + Environment.NewLine;
            }
        }
