在C#中实现SplayTrees，添加到树结构时出错 [英] Implementing SplayTrees in C#, error in adding to tree sturcture

问题描述

你好，
我正在尝试使用我发现的此类在此链接下在线实现splaytree:
https://raw.github.com/gist/940104/01bb918f4190b8e8016ab968724a3f0953c14416/SplayTree%602.cs [ ^ ]

香港专业教育学院做出了以下代码，以将用户的一组值添加到树中，但它给了我一个参数异常，即键已存在? 我做错了什么?

Hello,
I''m trying to use this class i found for implementing a splaytree online under this link:
https://raw.github.com/gist/940104/01bb918f4190b8e8016ab968724a3f0953c14416/SplayTree%602.cs[^]

ive made the following code to add a set of values from the user to the tree but it gives me an argument exception that the key already exists??
What am I doing wrong?

private void makeTreeBtn_Click(object sender, EventArgs e)
       {
SplayTree<int, int> tree = new SplayTree<int, int>();           

           values = values_textBox.Text;
           string [] split = values.Split(new Char [] {' ', ',' });

           foreach(string s in split)
           {
               int i = 1;
               try
               {
                   tree.Add(i, Convert.ToInt32(s));
               }
               catch (ArgumentException error)
               {
                   MessageBox.Show("Element with key " + i + " and value " + tree[i] + " already exists.\n"+error);
               }
               i++;
           }

           foreach (KeyValuePair<int, int> kvp in tree)
           {
              MessageBox.Show("\n" +kvp.Key+" "+kvp.Value);
           }

       }

推荐答案

我并不感到惊讶！取出不会导致问题的代码:

I''m not surprised! Taking out the code that doesn''t contribute to the problem:

foreach(string s in split)
{
    int i = 1;
        tree.Add(i, Convert.ToInt32(s));
    i++;
}

尝试将"i"的声明移出循环...

Try moving the declaration of "i" outside the loop...
