Hey there, this is my new challenge:

I have some info in a plain text file. I want to recover it and publish it to the user using C#. This text has some escape commands such as \n or \t. I tried with a RichTextBox and it doesn''t work :thumbsdown:.

Is there any method to do it? I know there is, but I can''t find it :(

推荐答案

如果您想摆脱所有这些转义字符，则可以使用建议的方法在来自MSDN.Social的该线程中 [ ^ ].

If you want to get rid of all these escaped characters then you could use the method suggested in this thread from MSDN.Social[^].

在表单上创建一个文本框(假设您正在使用Windows窗体)，然后使用以下代码:

Create a Textbox on your form (assuming you are using Windows Forms), then use this code:

textBox1.Multiline = true;
textBox1.Dock = DockStyle.Fill;
textBox1.Text = "\r\nHello\r\n\r\n\tHow are you?";

在Windows中，新行用"\ r \ n"表示，而不仅仅是"\ n".如果您的文件包含"\ n"字符，则可以使用正则表达式或String.Replace修复要显示的字符:

In Windows, a new line is represented by "\r\n" rather than just "\n". If you have a file that contains "\n" characters, you can use a regular expression or String.Replace to fix the characters for display:

textBox1.Text = "\nHello\n\n\tHow are you?".Replace("\n", "\r\n");

或:

Or:

textBox1.Text = System.Text.RegularExpressions.Regex.Replace("\nHello\n\n\tHow are you?", "(?<!\r)\n", "\r\n");

删除了我在此处忘记的一些测试代码.
