求一字符串解析方法问题
str="#0||1.txt||0.00 KB||~/Upload/FileUpload20121007073636062.txt||file-0#0||2.txt||0.00 KB||~/Upload/FileUpload20121007073640375.txt||file-1"

我想对上面的字符串先通过#0进行解析出两条数据，再通过||进行解析将得到的数据放入一个list集合中，最好是用正则表达式来实现，这样可以去掉中间的空格之类的，谢谢！

我先是这样写的
string pattern = "(?is)(?<=" + Regex.Escape("#0") + ").+?(?=" + Regex.Escape("#0") + ")";
Regex reg = new Regex(pattern);
MatchCollection mc = reg.Matches(str);
foreach (Match m in mc)
{
这中间的｜｜正则怎么写，同时要去掉空格
}

[解决办法]
这个正则真不会，先帮顶！
