如何将队列的值设置为另一个队列

Question

我如何将队列的值(不参考(插入另一个队列？它就像我在C (Queue＆lt;*Word>(中的点队一样工作，但是我想像这样复制缓冲区队列的值

a = 1;
int[] array = new int[1]
array[0] = a //array[0] now is 1
a = 0 // but array[0] doesn't change, array[0] is 1!

我有问题。

using word = System.Collections.Generic.Queue<char>;
Queue<word> words = new Queue<word>();  //word is the custom type, that was def in file top
word buffer = new word();
for (var symbol_count = 0; symbol_count < text.Length; ++symbol_count)
{
    if (text[symbol_count] != ' ' && text[symbol_count] != '.' && text[symbol_count] != ',')
    {
        buffer.Enqueue(text[symbol_count]); //store one char in word
    } 
    else 
    {
        buffer.Enqueue(text[symbol_count]); //store end of word symbol
        words.Enqueue(buffer);  //store one word in words queue, but compiler do it like I try to copy a reference of buffer, not it value!!!
        //System.Console.WriteLine(words.Count); DEBUG
        buffer.Clear(); //clear buffer and when i do this, value in words queue is deleted too!!!
    }
}

Answer 1

问题是您在循环中重复使用相同的buffer，因此，当您清除它时，所有对其的参考也将被清除。

相反，将本地buffer变量设置为对象的a new 实例，以使其任何更改都不会影响我们刚刚存储的参考：

foreach (char chr in text)
{
    buffer.Enqueue(chr);
    if (chr == ' ' || chr == '.' || chr == ',')
    {                     
        words.Enqueue(buffer);
        // reassign our local variable so we don't affect the others
        buffer = new Queue<char>();   
    }
}

当您将新单词保存到队列时(顺便说一句，您可能有一个错误的错误(

(

words.Enqueue(buffer);

您不应该使用buffer变量本身：它具有对临时数据的引用，您需要先制作它的副本，这将在下一行中不会修改。

尝试，例如

words.Enqueue(new word(buffer));
