今天反编译了一个项目，里面的Property 的形式变成了最原始的形式，如get_xxx(),set_xxx(val)，而且还很多，手动改的话要费很多时间，因此想用正则表达式的分组匹配进行替换，查了一下资料，vs里的分组符号使用{}，好象用（）是不行的，我试了好多次都没有成功，比如：
要将obj.get_Name()替换成obj.Name可以使用
get_{[^(]+}\(\)
替换为
\1
就可以了，\1就相当于{[^\(]+}这一部分，^\(表示非左括号的所有字符
如果要将obj.set_Name(“abcd”)替换为obj.Name = “abcd”可以使用如下的方法
set_{[^\(]+}\({[^\)]+}\)
替换为
\1 = \2
就可以了，另外在vs里：
:w可以匹配([a-zA-Z0-9]).
:c可以匹配([a-zA-Z]).
:d可以匹配([0-9]).
\n表示分组匹配里捕获到的子串，按序号1-9表示第一个至第九个子串，即\1-\9，\0表示整个匹配到的串。
msdn里有比较详细的说明，不过是英文的，地址如下：

Visual Studio
Regular Expressions
Regular expressions are a concise and flexible notation for finding and replacing patterns of text. The regular expressions used within Visual Studio are a superset of the expressions used in Visual C++ 6.0, with a simplified syntax.
You can use the following regular expressions in the Find, Replace, Find in Files or Replace in Files dialog boxes to refine and expand your search.
Note You must select the Use check box in the Find, Replace, Find in Files, and Replace in Files dialog boxes before using any of the following expressions as part of your search criteria.
The following expressions can be used to match characters or digits in your search string:
Expression
Syntax
Description
Any character
.
Matches any one character except a line break.
Maximal — zero or more
*
Matches zero or more occurrences of the preceding expression.
Maximal — one or more
+
Matches at least one occurrence of the preceding expression.
Minimal — zero or more
@
Matches zero or more occurrences of the preceding expression, matching as few characters as possible.
Minimal — one or more
#
Matches one or more occurrences of the preceding expression, matching as few characters as possible.
Repeat n times
^n
Matches n occurrences of the preceding expression. For example, [0-9]^4 matches any 4-digit sequence.
Set of characters
[]
Matches any one of the characters within the []. To specify a range of characters, list the starting and ending character separated by a dash (-), as in [a-z].
Character not in set
[^...]
Matches any character not in the set of characters following the ^.
Beginning of line
^
Anchors the match to the beginning of a line.
End of line
$
Anchors the match to the end of a line.
Beginning of word
<
Matches only when a word begins at this point in the text.
End of word
>
Matches only when a word ends at this point in the text.
Grouping
()
Groups a subexpression.
Or
|
Matches the expression before or after the OR symbol (|). Mostly used within a group. For example, (sponge|mud) bath matches "sponge bath" and "mud bath."
Escape
\
Matches the character following the backslash (\). This allows you to find characters used in the regular expression notation, such as { and ^. For example, \^ Searches for the ^ character.
Tagged expression
{}
Tags the text matched by the enclosed expression.
nth tagged text
\n
In a Find or Replace expression, indicates the text matched by the nth tagged expression, where n is a number from 1 to 9.
In a Replace expression, \0 inserts the entire matched text.
Right-justified field
\(w,n)
In a Replace expression, right-justifies the nth tagged expression in a field at least w characters wide.
Left-justified field
\(-w,n)
In a Replace expression, left-justifies the nth tagged expression in a field at least w characters wide.
Prevent match
~(X)
Prevents a match when X appears at this point in the expression. For example, real~(ity) matches the "real" in "realty" and "really," but not the "real" in "reality."
Alphanumeric character
:a

([a-zA-Z0-9]).
Alphabetic character

Matches a character given by Unicode value where #### is hexadecimal digits. You can specify a character outside the Basic Multilingual Plane (that is, a surrogate) with the ISO 10646 code point or with two Unicode code points giving the values of the surrogate pair.
The following table lists the syntax for matching by standard Unicode character properties. The two-letter abbreviation is the same as listed in the Unicode character properties database. These may be specified as part of a character set. For example, the expression [:Nd:Nl:No] matches any kind of digit.
