BitArray 是 C# 中用于表示一组位(bit)值的集合。 BitArray 属于 System.Collections 命名空间,主要用于处理二进制数据或进行位操作,相比使用布尔数组(bool[]),BitArray 更加高效,因为它以紧凑的方式存储每个位。 BitArray 类管理一个紧凑型的位值数组,它使用布尔值来表示,其中 true 表示位是开启的(1),false ...

创建一个包含指定对象的不可变数组。 C# publicstaticSystem.Collections.Immutable.ImmutableArray<T> Create<T> (T item1, T item2, T item3); 类型参数 T 数组中存储的元素的类型。 参数 item1 T 要存储在数组中的第一个对象。 item2 T 要存储在数组中的第二个对象。
傳回序列的第一個元素;如果序列中沒有包含任何元素,則傳回預設值。 FirstOrDefault<T>(ImmutableArray<T>.Builder) 傳回集合中第一個元素,如果集合是空的則傳回預設值。 FirstOrDefault<T>(ImmutableArray<T>, Func<T,Boolean>) 傳回序列中符合條件的第一個元素;如果找不到這類元素,則傳回預設值。Fi...

There can't be multiple matching methods that are equally good. Collection expressions can initialize explicitly typed variables of a collection type. If the variable isn't a collection or array type, or is implicitly typed (using var), a collection initializer can't be used. A ref struct ...
