我得到了航班预订网站的回复。我将此响应保存到一个字符串变量中，然后将此字符串拆分为字符，然后尝试将此输出保存在数据表中，但问题是数据格式不正确。

我得到了这个o / p：-

在此处输入图像描述

需要像这样的o / p：-

在此处输入图像描述

注意：- 我想将 J8 C7 D1 I0 S0 Y9 B9 添加到 M9 H9 Q9 K0 L0 U0 T0 E0 然后将结果字符串存储在单独的列中。这是我对客户理解的项目要求。

代码是： -

Here you should use string operation and regular expression. I solved your problem. Please run my code and let me know if you have any doubt. 

    int startindex = request.IndexOf(" 1  ");
    request = request.Substring(startindex - 1); //Remove the special character line from the input

    string subs;

    while (request.Trim() != ">") // Here we create the loop for execute whole string.
    {           
            int r1 = request.IndexOf("\r", 3);
            subs = request.Substring(0, r1); // Here we take the first line of the input.
            dr = dt.NewRow(); // Here we create the new row for each line.

            MatchCollection m1 = Regex.Matches(subs, @"\w{3}\s\d"); // Take the LAS 1 character from the line for merging the seat availability classes value.
            string origin = m1[0].Value; // Here we assign the origin city name to string variable.
            string destination = m1[1].Value; // Here we assign the destination city name to string variable.
            int end = subs.IndexOf(origin);
            int start = end - 1;

            dr["Origin"] = origin; // Here we bind the origin city name to data column.
            dr["Destination"] = destination; // Here we bind the destination city name to data column.

            request = request.Substring(subs.Length); // Here requset variable contain the substring after the took of first line for processing.
            r1 = request.IndexOf("\r\n", 3); // Here we are taking the index of second line.

            string replace = request.Substring(3, r1).TrimStart();

            string result = subs.Substring(0, start) + replace + subs.Substring(end); // here we merge the seat availability classes value.

            Regex regex = new Regex(@"(\s(\w\w\s){2,})"); // Here we create the regular expression for seat availability classes. 
            Match match1 = regex.Match(result);


            dr["COS"] = match1.ToString(); // Here we bind the seat availability classese to data column.
            dr["Segment"] = result.Substring(0, result.IndexOf(match1.ToString()) - 2); // Here we bind the Segments to data column.


            subs = result;
            start = subs.IndexOf(destination);
            dr["Details"] = subs.Substring(start + 5); // Here we bind the further(timing details) details of flight to data column.
            dt.Rows.Add(dr); // Here we are binding whole rows to data table. 

            request = request.Substring(r1); // requset variable contains the remaining substring.

    }

    GridView1.DataSource = dt;
    GridView1.DataBind(); // Here we are binding the whole data table to GridView.
    dt.Dispose(); // Here we dispose the datatable and free the memory.
