Answer 2

(1) \\red[^;]+
(2) (?<=\\cf[^ ]+\s+)\S+(?=\s*\\par)

Answer 3

这个
“ aaaaaaaaaa ” “ bbbbbbbbbbbbb ” “ cccccccccc ” ...
是根据什么规则？

Answer 4

    private static void TestRegex22()
    {
        string a = @"{\rtf1\ansi\ansicpg936\deff0\deflang1033\deflangfe2052{\fonttbl{\f0\fmodern\fprq6\fcharset134 \'cb\'ce\'cc\'e5;}{\f1\fnil ;}{\f2\fnil\fcharset134 \'b7\'bd\'d5\'fd\'d2\'a6\'cc\'e5;}{\f3\fnil\fcharset134 \'b7\'bd\'d5\'fd\'ca\'e6\'cc\'e5;}{\f4\fnil\fcharset134 \'bf\'ac\'cc\'e5_GB2312;}{\f5\fnil\fcharset134 \'c1\'a5\'ca\'e9;}{\f6\fnil\fcharset134 \'ba\'da\'cc\'e5;}{\f7\fswiss\fcharset0 Arial;}}

        Regex reg1 = new Regex(@"\\red[^;]+", RegexOptions.Compiled);
        Regex reg2 = new Regex(@"(?<=\\cf[^ ]+\s+)\S+(?=\s*\\par)", RegexOptions.Compiled);

    }输出\red0\green0\blue0
\red0\green255\blue255

\red165\green42\blue42
\red169\green169\blue169
\red255\green0\blue0
\red0\green255\blue0
\red255\green255\blue0
--------------神奇的分割线--------------
aaaaaaaaaa
bbbbbbbbbbbbb
cccccccccc
ddddddddddd
eeeeeeeeee
ffffffffffffffffffff

Answer 5

 这个是RTF格式的内容  aaaaaaaaaa   前面标记的是一个样式。  bbbbbbbbbbbbb  前面标记的又是另一个样式

Answer 6

 求“\red0\green0\blue0”  的  能不能限制下是在  {\colortbl ;\red0\green0\blue0;} 里的？ {\colortbl ;                   } 

Answer 7

“ aaaaaaaaaa ” “ bbbbbbbbbbbbb ”  这个之后 不一定有   \par   但是是在最后一个花括号之前的。。要怎么弄呢？

Answer 8

如果\par不一定有
Regex reg2 = new Regex(@"(?<=\\cf[^ ]+\s+)\S+(?=\s*\\par|})", RegexOptions.Compiled);
