Array.Contains() 总是错误的

Question

几天来我一直在为这个问题绞尽脑汁，并尝试了很多不同的方法。我在论坛上到处都是，尝试了我所看到的一切，但没有成功。我的问题可能是我没有覆盖，但我不知道如何让它工作。

我想检查包含 5,000 多个元素的数组是否包含用户输入的单词。这个词一个字符一个字符地输入，并组合成一个字符串（guessString）。然后我使用 .Contains() 来查看该单词是否在数组中。

Answer 1

嗯，你的 WordArray 总是空的。您将文件内容放入名为 AllWords.

的 local 变量中

永远不会在空数组中找到您的单词。

Answer 2

我已经把你那行不起作用的代码一字不差地复制了下来。然后，我获取了您所说的 WordArray 和 guessString 变量中的数据并进行了设置。然后我运行这个：

var WordArray = new [] { "WHICH", "THERE", "THEIR", "ABOUT" };
var guessString= "THERE";
bool match = WordArray.Contains(guessString);
Console.WriteLine(match);

match出来True.

您的变量不包含您认为的数据。

很可能您调用 .Split('\n') 的 content 实际上包含 Windows 行尾标记，因此是 "\r\n" 的组合。由于您仅在 '\n' 上拆分，因此 '\r' 可能保留在您的字符串中，因此 "THERE" 与 "THERE\r".

不匹配

试试这个：

.Split(new[] { Environment.NewLine }, StringSplitOptions.None);

如果您的代码在 Windows 或 Linux 上是运行，则以上行有效。请注意混合结尾的文件。
