AhEBAxEB / 8QAHwAAAQUBAQEBAQEAAAAAAAAAAAAAAAQAQQAcAQAQA / 8QAtRAAAgA如果需要，可以使用一些可用的库来解析邮件消息。我推荐开源OpenPop.NET：

http://sourceforge.net/projects/hpop [ ^ ]。



这个库编写得不是很好，但它完全适用于所有这些MIME标准，并在代码中包含一个POP3客户端。你可以直接使用它，或者只是用作参考，这也很有用。

另一种方法是使用String.Split：

  private   string  [] splitString =  new   string  [] { @    -  = _ NextPart_SMP _}; 
 
  private  List< string> getSections（ string  source）
 {
  return  source.Split（splitString，StringSplitOptions .RemoveEmptyEntries）.ToList（）; 
} 
 
 
   //  在方法中测试正文  
 
  私人 字符串 source =  @ 您的测试内容在这里;  
 
 List< string> result = getSections（source）; 
 
  if （result ==  null ） throw   new  EvaluateException（ 无法解析来源！）; 
 
  for （ int  i =  0 ; i <  result.Count; i ++）
 {
 Console.WriteLine（  Section：{0}值：{1}，i.ToString（），result [i]）; 
} 

请看下面的例子。

  string  pattern =    -  = _ NextPart_SMP（？< result>。*） -  = _ NextPart_SMP; 
 
正则表达式正则表达式= 新正则表达式（模式）; 
 
匹配匹配= regex.Match（   -  = _ NextPart_SMP_1d0087c4c718772_aee00768_00000001  -  = _ NextPart_SMP< /跨度>）; 
 
  if （match.Success）
 {
  string  result = match.Groups [  RESULT]。值; 
} 

这将给你_1d0087c4c718772_aee00768_00000001



祝你好运，

解决方案

If you want, you can use some available library to parse mail messages. I would recommend open-source OpenPop.NET:
http://sourceforge.net/projects/hpop[^].

This library is not perfectly well written, but it thoroughly works with all those MIME standards and contains a POP3 client in the code. You can use it directly, or simply use as a reference, which is also useful.

Another alternative is to use String.Split:

private string[] splitString = new string[]{@"--=_NextPart_SMP_"};

private List<string> getSections(string source)
{
    return source.Split(splitString, StringSplitOptions.RemoveEmptyEntries).ToList();
}


// test in a method body

private string source = @"Your test content goes here";

List<string> result = getSections(source);

if(result == null) throw new EvaluateException("can't parse source !");
            
for (int i = 0; i < result.Count; i++)
{
    Console.WriteLine("Section: {0} Value: {1}",i.ToString(),result[i]);
}

Hi,

please have a look at the following example.

string pattern = "--=_NextPart_SMP(?<result>.*)--=_NextPart_SMP";

Regex regex = new Regex(pattern);

Match match = regex.Match("--=_NextPart_SMP_1d0087c4c718772_aee00768_00000001--=_NextPart_SMP");

if(match.Success)
{
    string result = match.Groups["RESULT"].Value;
}

This will give you "_1d0087c4c718772_aee00768_00000001"
