推荐答案

有在从文件中读取文本没有转义字符。转义字符，当你写一个字符串中使用，例如在程序code。我假设你的意思是要与普通的空格替换任何写入空格字符。

There are no escape characters in a text that you read from a file. Escape characters are used when you write a string literal, for example in program code. I assume that you mean that you want to replace any write space characters with plain spaces.

您可以使用常规的前pression匹配空格字符，用空格代替。它更容易使用 File.ReadAllText 来读取文件中的文本：

You can use a regular expression to match white space characters and replace them with spaces. It's easier to use the File.ReadAllText to read the text from the file:

string text = Regex.Replace(File.ReadAllText(fileName), @"[\r\n\t ]+", " ");
