我想将所选行检索到一个单独的文本文件中，但我的代码只检索了所有行，而不是所选行
我想知道是否有一种方法可以检查我想要检索的行，我的意思是我想要从行中进行选择
我显示了数据表，希望按选择进行选择
请问我怎么做选择过程？？？

<table id="example" class="display" style="width:100%">
        <thead>
            <tr>
                <!-- <th>-</th>-->
                <th>DATE</th>
                <th>ORDBUS</th>
                <th>ORDSER</th>
                <th>SEQUEN</th>
                <th>HEUDEB</th>
                <th>HEUFIN</th>

                <th>Actions</th>
            </tr>
        </thead>
        <tbody>
            @foreach (DataRow row in Model.Tables[0].Rows)
            {
                <tr class="active-row">
                    <!-- <td><input type="checkbox" /> </td>-->
                    <td>@row["DATMVT"]</td>
                    <td>@row["ORDBUS"]</td>
                    <td>@row["ORDSER"]</td>
                    <td>@row["SEQUEN"]</td>
                    <td>@row["HEUDEB"]</td>
                    <td>@row["HEUFIN"]</td>

                    <td>
                        <button type="submit" class="btn btn-primary" value=Edit>EDIT</button>
                    </td>
                </tr>
            }
        </tbody>
    </table>
    <script> $("#btnGetData").click(function () {
            var selData = table.rows(".selected").data();
            alert(selData.length);
        });</script>
   
    @using (Html.BeginForm("ConvertToTextfile", "Display", FormMethod.Get))
    {
        <input type="submit" value="Submit" class="btn btn-success" id="btnGetData" />
    }

这就是

public ActionResult ConvertToTextfile()

        {
            string mySQL;
            DataTable table = new DataTable();
            DataSet myDataSet = new DataSet();
            mySQL = "Select * From MOUVEMSSE.Mouvem11 ";
            string connect = System.Configuration.ConfigurationManager.AppSettings["dsn_AS400"];
            string conn_string = connect + "UID=" + HttpContext.Session["Username"] + ";PWD=" + HttpContext.Session["Password"] + ";";

            db_tools.sg_connStr = conn_string;
            connection = db_tools.Connect();
            table = db_tools.ExecuteSelectCommand(mySQL, CommandType.Text);
            myDataSet.Tables.Add();

            string folderLocation = @"C:\Users\zarai\source\repos\Sms_Chauffeur\Sms_Chauffeur\Extractedfiles"; // your path to save the files 

            for (int i = 0; i<table.Rows.Count; i++)  // iterate each rows to get the value
           {
               string fileName = folderLocation + "\\" + "File-" + i + ".txt";  // file name for saving each row
               string contents = "";
               foreach (DataColumn col in table.Columns)  // iteate each column to get its corresponding value
                   contents += table.Rows[i][col].ToString() + "    ";  // concatenating the contents

               System.IO.File.WriteAllText(fileName, contents);  // create a text file and copy the contents
           }

            return View("data Extracted sucssessfuly");
        }
this is the controller
