例如上述字符串，怎样能获取到
name="expressDealId" 111209511524_1
name="expressCompanyId" wu023shangcheng

目测，应该可以用这个代码
View Code
public void test() { string s = ""; int start = 0; List<data> list = new List<data>(); do { int index = s.IndexOf("name=\"", start); start = index + 6; if (start <= 6 || start > s.Length) break; int end = s.IndexOf("\"", start); if (end < 0) break; data item = new data(); item.Name = s.Substring(start, end - start); start = end; index = s.IndexOf("\r\n\r\n", start); start = index + 4; end = s.IndexOf("\r\n", start); if (start <= 4 || end < 0) break; item.Value = s.Substring(start, end - start); list.Add(item); } while (start > 6); } public class data { public string Name { set; get; } public string Value { set; get; } }

没看明白啥意思？
就是说怎么样解析，可以得到这个结果name="expressDealId" 111209511524_1
name="expressCompanyId" wu023shangcheng

先用换行符把字符串分解成字符串数组，FOR循环，然后如果有name关键字就截取name的值(最好是正则表达式)，然后I+3(或者判断Content-Transfer-Encoding关键字的下一个循环)取值

用正则表达式实现的C#代码如下：
[Test] public void RegexTest() { var text = System.IO.File.ReadAllText("f:\\temp\\text.txt"); var matches = Regex.Matches(text, @"(name=""[^""]+"")(?:\r\n[^\r\n]+){2}\r\n([^\r\n]+)"); foreach (Match match in matches) { Console.WriteLine(match.Groups[1] + " " + match.Groups[2]); } }
