方法

Clear()	从不可变队列中移除所有对象。Removes all objects from the immutable queue.
Dequeue()	移除位于不可变队列开始处的元素，并返回新队列。Removes the element at the beginning of the immutable queue, and returns the new queue.
Dequeue(T)	移除位于不可变队列开始处的项，并返回新队列。Removes the item at the beginning of the immutable queue, and returns the new queue.
Enqueue(T)	将元素添加到不可变队列的末尾，并返回新队列。Adds an element to the end of the immutable queue, and returns the new queue.
Equals(Object)	确定指定的对象是否等于当前对象。Determines whether the specified object is equal to the current object. (继承自 Object)
GetEnumerator()	返回一个循环访问不可变队列的枚举器。Returns an enumerator that iterates through the immutable queue.
GetHashCode()	用作默认哈希函数。Serves as the default hash function. (继承自 Object)
GetType()	获取当前实例的 Type。Gets the Type of the current instance. (继承自 Object)
MemberwiseClone()	创建当前 Object 的浅表副本。Creates a shallow copy of the current Object. (继承自 Object)
Peek()	返回位于不可变队列开始处的元素但不将其移除。Returns the element at the beginning of the immutable queue without removing it.
PeekRef()	获取对队列前部元素的只读引用。Gets a read-only reference to the element at the front of the queue.
ToString()	返回一个表示当前对象的 string。Returns a string that represents the current object. (继承自 Object)

显式界面实现

IEnumerable.GetEnumerator()	返回循环访问集合的枚举数。Returns an enumerator that iterates through a collection.
IEnumerable<T>.GetEnumerator()	返回一个循环访问集合的枚举器。Returns an enumerator that iterates through the collection.
IImmutableQueue<T>.Clear()	从不可变队列中移除所有元素。Removes all elements from the immutable queue.
IImmutableQueue<T>.Dequeue()	移除位于不可变队列开始处的元素，并返回新队列。Removes the element at the beginning of the immutable queue, and returns the new queue.
IImmutableQueue<T>.Enqueue(T)	将元素添加到不可变队列的末尾，并返回新队列。Adds an element to the end of the immutable queue, and returns the new queue.

扩展方法

Dequeue<T>(IImmutableQueue<T>, T)	移除位于不可变队列开始处的项，并返回新队列。Removes the item at the beginning of the immutable queue, and returns the new queue.
CopyToDataTable<T>(IEnumerable<T>)	在给定其泛型参数 `T` 为 DataTable 的输入 DataRow 对象的情况下，返回包含 IEnumerable<T> 对象副本的 DataRow。Returns a DataTable that contains copies of the DataRow objects, given an input IEnumerable<T> object where the generic parameter `T` is DataRow.
CopyToDataTable<T>(IEnumerable<T>, DataTable, LoadOption)	在给定其泛型参数 `T` 为 DataRow 的输入 DataTable 对象的情况下，将 IEnumerable<T> 对象复制到指定的 DataRow。Copies DataRow objects to the specified DataTable, given an input IEnumerable<T> object where the generic parameter `T` is DataRow.
CopyToDataTable<T>(IEnumerable<T>, DataTable, LoadOption, FillErrorEventHandler)	在给定其泛型参数 `T` 为 DataRow 的输入 DataTable 对象的情况下，将 IEnumerable<T> 对象复制到指定的 DataRow。Copies DataRow objects to the specified DataTable, given an input IEnumerable<T> object where the generic parameter `T` is DataRow.
Cast<TResult>(IEnumerable)	将 IEnumerable 的元素强制转换为指定的类型。Casts the elements of an IEnumerable to the specified type.
OfType<TResult>(IEnumerable)	根据指定类型筛选 IEnumerable 的元素。Filters the elements of an IEnumerable based on a specified type.
