允许用户在TextBox中输入转义字符 [英] Allow user to enter escape characters in a TextBox

问题描述

我有一个Windows.Forms.TextBox，我想允许用户输入转义序列，然后解释为它们所代表的字符。

I have a Windows.Forms.TextBox that I'd like to allow the user to enter escape sequences that are then interpreted as the character they represent.

例如，如果输入以下内容：

For example, if the following is entered:

Hello\r\nWorld

我希望将其存储为字符数组：

I'd like it to be stored as the character array:

   H     e     l     l     o    \r    \n     W     o     r     l     d
0x48, 0x65, 0x6C, 0x6C, 0x6F, 0x0D, 0x0A, 0x57, 0x6F, 0x72, 0x6C, 0x64

到目前为止，我使用以下内容来处理'\r'和'\\\
'，但我也喜欢能够处理任何其他转义序列，如 \\\ （ctrl + z）或 \\\ （esc）

Thus far, I'm using the following to handle '\r' and '\n', but I'd also like to be able to handle any other escape sequence, like \u001A (ctrl+z), or \u001B (esc)

string str = txtBox.Text.Replace("\\r","\r").Replace("\\n","\n");

...必须有一个更通用的方法来处理这个...

...There has to be a more general way of handling this...

推荐答案

您可以尝试使用 System.Text.RegularExpressions.Regex.Unescape 静态方法：

You could try to use the System.Text.RegularExpressions.Regex.Unescape static method:

string str = Regex.Unescape(txtBox.Text);

但不幸的是，它主要适用于正则表达式控制字符。

But unfortunately it applicable mainly for Regex control characters.
