从Dictionary<string、object>中提取数组值

Dictionary<string, object> dictionary = new Dictionary<string, object>();
dictionary.Add("key1", "value1");
dictionary.Add("key2", new List<int> { 1, 2, 3 });
dictionary.Add("key3", "value3");

string key = "key2";
if (dictionary.ContainsKey(key))
{
    if (dictionary[key] is List<int>)
    {
        List<int> arrayValue = (List<int>)dictionary[key];
        // 对数组值进行处理
        foreach (int value in arrayValue)
        {
            // 处理数组中的每个元素
            Console.WriteLine(value);
        }
    }
    else
    {
        // 键对应的值不是数组类型
        Console.WriteLine("The value is not an array.");
    }
}
else
{
    // 字典中不存在该键
    Console.WriteLine("The key does not exist in the dictionary.");
}
