C# Dictionary的使用執行個體代碼

複製代碼 代碼如下:class Dirctonary
{
public void DictionaryGet()
{
Dictionary<int, string> productList = new System.Collections.Generic.Dictionary<int, string>();
productList.Add(1, "ProductionOne");
productList.Add(2, "ProductionTwo");

foreach (KeyValuePair<int, string> production in productList)
{
MessageBox.Show(string.Format("{0},{1}", production.Key, production.Value));
}
//MessageBox.Show(productList.Count.ToString());
//MessageBox.Show(productList[1].ToString());
Dictionary<int, string>.KeyCollection keys = productList.Keys;
foreach (var item in keys)
{
MessageBox.Show(item.ToString());
}

Dictionary<int, string>.ValueCollection collection = productList.Values;
foreach (var item in collection)
{
MessageBox.Show(string.Format("{0}", item));
}
//productList.Remove(1);
//productList.Clear();
MessageBox.Show("判斷是否包含索引值對中的鍵為”1“的值");
if (productList.ContainsKey(1))
{
MessageBox.Show(productList[1]);
}
MessageBox.Show("判斷是否包含索引值對中的值為”ProductionTwo“的值");
if (productList.ContainsValue("ProductionTwo"))
{
MessageBox.Show(string.Format("{0}", "this really exists"));
}
}
