Array.Contains() 总是假的

Question

几天来，我一直在努力解决这个问题，并尝试了很多不同的方法。我一直在论坛上，尝试了我所看到的一切，但没有运气。我的问题可能是我没有覆盖，但我不知道如何让它工作。

我想检查一个包含 5,000 多个元素的数组是否包含用户输入的单词。单词逐个字符输入并组合成一个字符串（guessString）。然后我使用 .Contains() 查看该单词是否在数组中。

Answer 1

我已将您的那行不起作用的代码逐字复制。然后，我获取了您所说的位于WordArray 和guessString 变量中的数据并进行了设置。然后我运行了这个：

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' 可能仍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 上运行，则上述行有效。请注意混合结尾的文件。

Answer 2

嗯，你的WordArray 总是空的。您将文件内容放入名为 AllWords 的 local 变量中。

您的单词永远不会在空数组中找到。
