解析正文时用的一个函数~

static ArrayList split(ArrayList list) {
		int n = list.Count;
		if (n == 0) {
			return new ArrayList();
		}
		ArrayList ret = new ArrayList();
		string res = "";
		for (int i = 0;i < n;i++) {
			if ((string)list[i] == "This is a multi-part message in MIME format.") {
				continue;
			}
			if (((string)list[i]).Contains("------=_NextPart")) {
				if (res.Trim() != "") {
					ret.Add(GetMailText(res));
				}
				res =  (string)list[i] + "\r\n";
			} else {
				res = res + (string)list[i] + "\r\n";
			}
		}
		if (res.Trim() != "") {
			ret.Add(GetMailText(res));
		}
		
		return ret;
	}
