在字符串中找到的正则表达式替换匹配项

Question

I am using a Regex to find a pattern within a string. After I find a match I would then like to remove it from the existing string.

For example:

starting string ex: "Billed Hours (.5);" 
converted string: "Billed Hours"

The regex pattern I am using is @"([az.]+);$" - Not sure if this is correct, I want to check that only whole numbers or decimals are within the parentheses. If the pattern matches then remove parentheses, the value inside as well as the following semi-colon.

This is what I have so far:

string testString = "Billed Hours (.5);"
testString = Regex.Replace(testString, @"\([a-z.]+\);$", "");

This is in C#.

Any ideas?

Answer 1

考虑...

string testString= Regex.Replace(testString, @"\(\d*\.?\d*]*\);$", "");

Answer 2

Try the regex:

@"\s+\([^)]+\);$"

And replace by nothing.

The \\s+ is to avoid having to trim spaces and [^)]+ matches any character except closing paren.
