使用正则表达式提取字符串!

[zwl850918]

helloworld:myname is tianya

MIME-Version: 1.0
Content-Type: Multipart/report;
report-type=delivery-status;

-----Content-Description: Delivery error report

我想使用正则表达式 c#提取:
MIME-Version: 1.0
Content-Type: Multipart/report;
report-type=delivery-status;

应该怎么写?

[wuhq030710914]

MIME-Version[\s\S]+(?=---)

好像不行...而且helloworld:myname is tianya 与-----Content-Description: Delivery error report 之间的字符串是动态的..

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;

namespace ConsoleApplication4
{
    class Program
    {
        static void Main(string[] args)
        {
            string strText = "helloworld:myname is tianya\r\n\r\nMIME-Version: 1.0\r\nContent-Type: Multipart/report;\r\nreport-type=delivery-status;\r\n\r\n-----Content-Description: Delivery error report";
            Console.WriteLine(strText);
            Console.WriteLine("正则表达式匹配的结果如下:");
            Console.WriteLine(Regex.Match(strText, @"(?<result>MIME-Version[\s\S]+(?=-----))").Groups[0].ToString()/*.Result("${result}")*/);
            Console.ReadLine();
        }
    }
}

是动态生成的话,试试

((?<=\r\n)[\s\S]+(?=-----))

strText是动态改变的 不变只是
helloworld:myname is tianya 和-----Content-Description: Delivery error report 我取的就是动态改变的字符串

((?<=helloworld:myname is tianya)[\s\S]+(?=-----))
