无法在c#中看到列表中的值

Question

我有以下代码:但我无法响应在列表中写入值以进行调试...

 public void LottoWinners(object sender, EventArgs e)
    {

        Dictionary<int, int> number = new Dictionary<int, int>();
        Random generator = new Random();
        while (number.Count < 6)
        {
            number[generator.Next(1, 49)] = 1;
        }

        int[] lotto = number.Keys.OrderBy(n => n).ToArray();

       List<int> lst = lotto.OfType<int>().ToList();


       StringBuilder builder = new StringBuilder();
       for (int i = 0; i < lst.Count; i++) // Loop through List with for
       {
           builder.Append(lst).Append("|"); // Append string to StringBuilder
       }
       string result = builder.ToString(); // Get string from StringBuilder

       Response.Write(result);

    }

但我所看到的只是我的结果.我应该看到我的名单的价值!

System.Collections.Generic.List`1

你需要这样做:

builder.Append(lst[i])

获取您尝试访问的列表元素.目前你只是附加整个列表,这没有意义.
