(1)循环遍历字典中的元素：

List<IDictionary<object, object>> items = (List<IDictionary<object, object>>)dictItems.Values[i_page];

if (items != null && items.Count > 0)

{

for (int k = 0; k < items.Count; k++)

{

IDictionary<object, object> item = (IDictionary<object, object>)items[k];

string url = "";

string pic = "";

foreach (KeyValuePair<object, object> kvp in item)

{

if (kvp.Key.ToString().ToLower().Contains("url"))

{

url = kvp.Value.ToString();

}

if (kvp.Key.ToString().ToLower().Contains("pic"))

{

pic = kvp.Value.ToString();

}

(2)给字典添加元素：

List<IDictionary<object, object>> items = null;

Dictionary<object, object> item = new Dictionary<object, object>();

item["Url"] = dr["url"].ToString();

item["Pic"] =dr["pic"].ToString();

items.Add(item);
