存储多个真假值列表的最佳方法 [英] Best way to store multiple lists of true false values

问题描述

这只是为了解决好奇心 - 假设，在我的 C# 项目中，我有一个包含数百万个字符串的列表，每个字符串如下:

This is just to settle a curiosity - Suppose, in my C# project, I have a list containing millions of strings, each along the following lines:

"123Hi1234Howdy"
"Hi1Howdy23"
....

我需要知道的是，对于字符串中的每个字符，它是数字还是字母.

And all I need to know is, for each character in the string, if it is a digit or is it a letter.

所以，我认为存储它的最简单方法是 0 和 1 或 True/False.因此，在上面的示例中，假设我可以分配 IsLetter = 1 和 IsDigit = 0，我可以将每一行转换为:

So, I was thinking the easiest way to store this would be as 0's and 1's or True / False. So, in the example above, assuming I could assign IsLetter = 1 and IsDigit = 0, I could transform each line to:

"123Hi1234Howdy"  >> 00011000011111
"Hi1Howdy23"      >> 1101111100
....

这在我看来是存储我正在寻找的数据的最有效方式(但如果我错了，请已经纠正我 - 我仍然几乎编程新手).

That seems to me to be the most efficient way to store the data I'm looking for (but please do already correct me if I'm wrong on this - I'm still pretty much a newbie with programming).

因此，编写循环一行并检查每个字符是数字还是字母并将其转换为 true/false 或 1/0 的代码非常简单.我的问题是存储每行输出的最佳方式是什么?

So, writing the code that loops through a line and checks for whether each character is a digit or a letter and converting it to true/false or 1/0 is easy enough. My question is what would be the best way to store each line's output?

我应该将每一行的输出存储为一个位数组吗?它是否可以存储为其他类型(例如整数)，然后可以转换回一系列位?它应该存储为布尔数组吗?关于存储这个的最佳方式还有其他想法吗?当这一切都说完了，我需要有一个我可以知道的清单，例如:

Should I store each line's output as a bit array? Could it be stored as some other type (maybe, say, integer) that could then be converted back to a series of bits? Should it be stored as a boolean array? Any other thoughts on the best way to store this? When it's all said and done, I need to have a list where I can know, for example:

myList[0] = 00011000011111
myList[1] = 1101111100

然后，因此 myList[0] <>myList[1]

推荐答案

您可以为每个单词使用 BitArray 并将位设置为 true 或 false，如果它们是数字或不是数字.请参阅此可能的解决方案:

You could use a BitArray for each word and set the bits to true or false if they are a digit or not. See this possible solution:

void Main()
{
    string[] words = 
    {
        "123Hi1234Howdy", 
        "Hi1Howdy23"
    };

    //Create an array of BitArray
    var bArrays = words.Select(w => new BitArray(w.Select(c => char.IsDigit(c)).ToArray()));

    //You can also create string too
    var strings = words.Select(w => new string(w.Select(c => char.IsDigit(c) ? '1' : '0').ToArray())).ToArray();


}

这不一定是最快或最有效的.我想这取决于您打算对字符串做什么，但至少它很简单！

This is not necessarily the fastest or most efficient. I guess it depends on what you intend to do with the strings, but at least it's simple!
