C＃-Regex使用点替换任何字符。 在括号[]中

Question

Example:

string str = "Example[1]";
string output = Regex.Replace(str, "[.]", "");

But it doesnt work, the output is still: Example[1]

I though the result will be "Example" only?

Please help :(

Answer 1

Your approach is correct.. just use escape characters for brackets..

string output = Regex.Replace(str, @"\[.\]", "");

Output : Example

EDIT : if you have more than one characters in brackets.. use "\\[.+?\\]"

Answer 2

Use the following expression:

string output = Regex.Replace(str, @"\[\d+\]", "");

It looks for symbol [ , any number of digits and symbol ]
