在线等—字符串的切割，坐等高手

[消失的尘芥]

string str = "all(a=2,b=3)and dfdsafd all(c=4,d=5)";

首先取出字符串

“2 3 4 5”要求分组，“2，3”取出后要作为一个参数传递到一个方法，然后“4,5”

最后替换字符串 把“all(...)“替换为其它字符串，替换后的格式为字符串为：

string str = "ss and dfdsafd ff";

RegEx

all\(a=(\d+),b=(\d+)\).+all\(c=(\d+),d=(\d+)\)

[人生难得一只鸡]

  string tempStr = @"all(a=2,b=3)and dfdsafd all(c=4,d=5)"; //File.ReadAllText(@"C:\Documents and Settings\Administrator\桌面\Test.txt", Encoding.GetEncoding("GB2312"));
            string pattern = @"(?im)all\([^=]+=([^,]+),[^=]+=([^,]+)\)";
            MatchCollection mc = Regex.Matches(tempStr, pattern, RegexOptions.IgnoreCase | RegexOptions.Multiline);
            foreach (Match m in mc)
            {
                //循环输出
                string title = m.Value;//all(a=2,b=3)
                string num_1 = m.Groups[1].Value;//2
                string num_2 = m.Groups[2].Value;//3
                tempStr = Regex.Replace(tempStr,pattern,"ss");//循环替换
         

            }

我真是无聊
下面是刚才代码的输出：

5
完整匹配：
all(a=2,b=3)and dfdsafd all(c=4,d=5)
匹配a的值：
2
匹配b的值：
3
替换后：
_1st value_and dfdsafd _2nd value_
