我有一个字符串，我必须在其中找到 PNR 号码。要获得 PNR 号码，我必须检查两个条件：

乘客中的第一位应该不止一个。

第二个字符串包含 ITINERARY REBOOKED。

如果两个条件都满足，则仅从字符串中提取 PNR 编号，否则不返回任何内容。

我的代码满足了我的第一个条件。

public DataTable GetPnr(List<string> request) // Here we create the function for get pnr.
{
    dt.Columns.Add("PNR", typeof(string));
    foreach (string data in request)
    {
        string item = data;
        dr = dt.NewRow();
        if (item.ToLower().Contains("itinerary rebooked") || item.ToLower().Contains("itineraryrebooked")) // Condition for operated by cases
        {
            Regex regexs = new Regex(@"(\s[A-Z0-9]{6}\s{2})"); // Regular operation for PNR.
            foreach (Match m in regexs.Matches(item))
            {
                output = m.ToString(); // Here we store the PNR value in output string variable.
            }
            dr["PNR"] = output;
            dt.Rows.Add(dr);
        }
    }
    return dt;
}

现在，当我使用正则表达式在我的函数中使用的同一个正则表达式中检查多个乘客时，不会返回任何输出

这是我希望检查两个条件的字符串：

}

根据我的代码，我采用所有包含 ITINERARY REBOOKED 的 PNR，但我也想要如果我只有一个带有 ITINERARY REBOOKED 的人，那么它不会像在 ymt3 中那样获取那个 PNR 号码我有 ITINERARY REBOOKED 条件但只有一个人所以我不想取 PNR 号码

试试这个代码...

 public DataTable GetPNR(List<string> Request)  // Here we create the function for get pnr.
    {
        dt.Columns.Add("PNR", typeof(string));

        foreach (string data in Request)
        {
            string item = data;
            dr = dt.NewRow();

            Regex regex = new Regex(@"(\d+\.[a-zA-Z]\S(.+))", RegexOptions.IgnoreCase | RegexOptions.Compiled);
            foreach (Match m in regex.Matches(item))
            {
                name = m.ToString();
            }

            if((item.ToLower().Contains("itinerary rebooked") || item.ToLower().Contains("itineraryrebooked"))&&name!=null) // Condition for operated by cases
            {
                Regex regexs = new Regex(@"(\s[A-Z0-9]{6}\s{2})"); // Regular operation for PNR.
                foreach (Match m in regexs.Matches(item))
                {
                    output = m.ToString(); // Here we store the PNR value in output string variable.
                }


            }
            dr["PNR"] = output;
            dt.Rows.Add(dr);
        }
        return dt;
    }`enter code here`
