class Program
{
    static void Main()
    {
        // 创建一个字典
        Dictionary<string, int> myDictionary = new Dictionary<string, int>();

        // 向字典中添加键值对
        myDictionary.Add("apple", 10);
        myDictionary.Add("banana", 5);
        myDictionary.Add("orange", 8);

        // 或者使用索引器
        myDictionary["grape"] = 15;

        // 打印字典中的键值对
        foreach (var kvp in myDictionary)
        {
            Console.WriteLine("Key: " + kvp.Key + ", Value: " + kvp.Value);
        }
