Dictionary <string，int =“”>没有值</string，>

Question

我将值放入字典时遇到问题。

我的代码：

Dictionary<string, Dictionary<string, int>> cnDict = new Dictionary<string, Dictionary<string, int>>();

Dictionary<string, int> cn = new Dictionary<string,int>();

cn.Add("DynamicPanel_1", 0);
cn.Add("DynamicPanel_3", 1);
cn.Add("DynamicPanel_4", 0);
this.cnDict.Add("DynamicPanel_2", cn);

cn.Clear();

cn.Add("DynamicPanel2", 1);
cn.Add("DynamicPanel3", 0);
this.cnDict.Add("DynamicPanel1", cn);
foreach(KeyValuePair<string, int> pos in cnDict["DynamicPanel_2"])
{
    MessageBox.Show("DynamicPanel_2 has values: "+ pos.Key + " ----> " + pos.Value.ToString()); ;
}

foreach (KeyValuePair<string, int> pos in cnDict["DynamicPanel_1"])
{
    MessageBox.Show("DynamicPanel_1 has values: " + pos.Key + " ----> " + pos.Value.ToString()); ;
}

此代码显示错误消息：

• DynsmicPanel_2的值为：DynamicPanel_2 ----＆gt; 1

• DynsmicPanel_2的值为：DynamicPanel_3 ----＆gt; 0

• DynsmicPanel_1的值为：DynamicPanel_2 ----＆gt; 1

• DynsmicPanel_1的值为：DynamicPanel_3 ----＆gt; 0

应该是：

• DynsmicPanel_2的值为：DynamicPanel_1 ----＆gt; 0
• DynsmicPanel_2的值为：DynamicPanel_3 ----＆gt; 1

• DynsmicPanel_2的值为：DynamicPanel_4 ----＆gt; 0

• DynsmicPanel_1的值为：DynamicPanel_2 ----＆gt; 1

• DynsmicPanel_1的值为：DynamicPanel_3 ----＆gt; 0

我做错了什么？

将相同的cn对象添加两次到cnDict字典。创建新对象：将cn.Clear();替换为cn = new Dictionary<string,int>();
