我现在已经查看所有内容太久了，看不出有什么不妥。我正在获取一个 100% 有数据的文件（并在没有任何数据的情况下使用 try catch 块），并处理其信息，然后将其吐回文本文件中。我没有得到任何输出，我觉得（由于我不得不使用多少次 ? 来消除空文件警告）我的错误存在于 fileContent = reader?.ReadLine()?.ToLower(); 行或 var words = fileContent?.Split(' ', StringSplitOptions.RemoveEmptyEntries);线。任何帮助将不胜感激
编辑：通过将 reader?.readLine()?.ToLower(); 更改为 reader.readToEnd() 并分离 fileContent = fileContent.toLower().
来修复我的文件 IO 问题
现在遇到对同一个文件进行多次迭代的问题。当输入我的测试数据时（其中我只是使用全部大写的原始口袋妖怪列表），我得到了它迭代的每个单词的输出（我不确定我明确在哪里声明以单词形式输出每个单词），我得到了相同内容的多个输出。
这是我更新的代码：`private async void btnClickThis_Click(object sender, EventArgs e)

//使用示例代码来自：https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.filedialog?view=windowsdesktop-6.0

var filePath = string.Empty;

int lengthMax = 0;
//for storing first and last words alphabetically

String last = "";

这是我的文件输出，它应该是一个格式化的文本文件，不显示大写字母（检查），第一个和最后一个单词按字母顺序排列（最后一个有效，第一个无效），最长的单词（检查），和元音最多的单词（检查）。

在这里您尝试找到第一个（最小）单词。
string first = "";
....
if (String.Compare(word, first) < 0)
{
first = word;
}
但是“”出现在所有字符串之前。所以比较总是错误的。做
string first = "";
....
if (String == "" || String.Compare(word, first) < 0)
{
first = word;

我现在已经查看所有内容太久了，看不出有什么不妥。我正在获取一个 100% 有数据的文件（并在没有任何数据的情况下使用 try catch 块），并处理其信息，然后将其吐回文本文件中。我没有得到任何输出，我觉得（由于我不得不使用多少次 ? 来消除空文件警告）我的错误存在于 fileContent = reader?.ReadLine()?.ToLower(); 行或 var words = fileContent?.Split(' ', StringSplitOptions.RemoveEmptyEntries);线。任何帮助将不胜感激
编辑：通过将 reader?.readLine()?.ToLower(); 更改为 reader.readToEnd() 并分离 fileContent = fileContent.toLower().
现在遇到对同一个文件进行多次迭代的问题。当输入我的测试数据时（其中我只是使用全部大写的原始口袋妖怪列表），我得到了它迭代的每个单词的输出（我不确定我明确在哪里声明以单词形式输出每个单词），我得到了相同内容的多个输出。
这是我更新的代码：`private async void btnClickThis_Click(object sender, EventArgs e) { //使用示例代码来自：https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.filedialog?view=windowsdesktop-6.0 //打开文件对话框并允许选择

这是我的文件输出，它应该是一个格式化的文本文件，不显示大写字母（检查），第一个和最后一个单词按字母顺序排列（最后一个有效，第一个无效），最长的单词（检查），和元音最多的单词（检查）。

在这里您尝试找到第一个（最小）单词。
string first = "";
....
if (String.Compare(word, first) < 0)
{
first = word;
}
但是“”出现在所有字符串之前。所以比较总是错误的。做
string first = "";
....
if (String == "" || String.Compare(word, first) < 0)
{
first = word;
}
