原因是:使用ContainsKey,如果键存在,则会在每次循环中再次取值,但TryGetValue,会直接存储结果值,然后马上用于求和。 参考网址: https://www.dotnetperls.com/trygetvalue https://blog.csdn.net/qq_38721111/article/details/83508909 https://blog.csdn.net/joyhen/article/details/9310743 代码存于:..CSharpBasic...

get()方法语法:dict.get(key, default=None) 1. 先定义字典>>>dict = {'A':1, 'B':2} 2. 当key值存在于dict.keys()中时,调用get()方法,返回的是对应的value值>>>print(dict.get('A')) 返回为:1 3. 当key值不存在于dict.keys()中时,调用get()方法,返回的是None>>>print(dict.get('C'...
然后我们假设需要执行一个Add操作,dictionary.Add("a","b"),其中key = "a",value = "b"。 根据key的值,计算出它的 hashCode。我们假设"a"的 hash 值为 6(GetHashCode("a") = 6)。 通过对 hashCode 取余运算,计算出该 hashCode 落在哪一个 buckets 桶中。现在桶的长度(buckets.Length)为 4,那么就...
1、首先可以通过‘键’来找到访问字典所需要的值，类似于列表和元组的访问方式。2、如果‘键’在字典里不存在，则就会出现报错。3、所以就需要判断‘键’是否存在。4、也可以使用get( )方法获取指定键的值。注意事项：C#是一种安全的、稳定的、简单的、优雅的，由C和C++衍生出来的面向对象的编程语言...
