Question

我收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然后我将此字符串拆分为字符然后我尝试将此输出保存在数据表上但问题是数据格式不正确。

我得到了这个o / p： -

enter image description here

需要这样的o / p： -

enter image description here

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： -

这里你应该使用字符串操作和正则表达式。我解决了你的问题。如果您有任何疑问，请运行我的代码并告诉我。

    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.

将字符串拆分为数据表
