字典 <string, int> 沒有價值

Question

將值放入Dictionary中時遇到問題。

我的代碼：

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()); ;
}

此代碼顯示錯誤消息：

• DynsmicPanel_2具有值：DynamicPanel_2 ----> 1

• DynsmicPanel_2具有值：DynamicPanel_3 ----> 0

• DynsmicPanel_1具有值：DynamicPanel_2 ----> 1

• DynsmicPanel_1具有值：DynamicPanel_3 ----> 0

應該：

• DynsmicPanel_2具有值：DynamicPanel_1 ----> 0
• DynsmicPanel_2具有值：DynamicPanel_3 ----> 1

• DynsmicPanel_2具有值：DynamicPanel_4 ----> 0

• DynsmicPanel_1具有值：DynamicPanel_2 ----> 1

• DynsmicPanel_1具有值：DynamicPanel_3 ----> 0

我做錯了什么？

謝謝

您將相同的cn對象兩次添加到cnDict字典。 創建新對象：替換cn.Clear(); by cn = new Dictionary<string,int>();
