HashSet<T>(Int32) 初始化HashSet<T>类的新实例,该实例为空,但为capacity项保留空间,并为集类型使用默认相等比较器。 HashSet<T>(Int32, IEqualityComparer<T>) 初始化HashSet<T>类的新实例,该实例使用集类型的指定相等比较器,并且有足够的容量来容纳capacity元素。
Console.WriteLine((int)ht["A"] + 1);//编译通过,输出结果为:2 Console.WriteLine(dic["A"] + 1); 1. 2. 3. 4. 5. 6. 7. 第二、读取数据的顺序与添加数据的顺序的一致性 Dictionary和Hashtable的读取数据的顺序和添加数据时的数据的顺序的一致性均不能够保证,或者可以说没有一致性。
public HashSet(int initialCapacity, float loadFactor) Constructs a new, empty set; the backingHashMapinstance has the specified initial capacity and the specified load factor. Parameters: initialCapacity- the initial capacity of the hash map
