C#winform从api拿到的json数据如何转成表格？数据要指定的数据，不是全部

Question

这是我写的触发代码，现在显示的是全部data里面的内容，我只需要一部分data里面的，比如说L值，K值，而不要全部显示，求请教

string url = "xxx";
string jsonParas = "workorder_id=" + 4 + "&" + "product_id=" + 1 + "&" + "process_no=" + 10 + "&" + "process_no_order=" + 1 + "&";
string getJson = HttpUitls.Post(url,jsonParas,"POST");
DataTable x = JsonToDataTable(getJson);
dataGridView1.DataSource = x;
dataGridView1.Rows[0].Selected = false;

JsonToDataTable的方法代码

public static DataTable JsonToDataTable(string strJson)
        {
            //转换json格式
            strJson = strJson.Replace(",\"", "*\"").Replace("\":", "\"#").ToString();
            //取出表名
            var rg = new Regex(@"(?<={)[^:]+(?=:\[)", RegexOptions.IgnoreCase);
            string strName = rg.Match(strJson).Value;
            DataTable tb = null;
            //去除表名
            strJson = strJson.Substring(strJson.IndexOf("[") + 1);
            strJson = strJson.Substring(0, strJson.IndexOf("]"));

            //获取数据
            rg = new Regex(@"(?<={)[^}]+(?=})");
            MatchCollection mc = rg.Matches(strJson);
            for (int i = 0; i < mc.Count; i++)
            {
                string strRow = mc[i].Value;
                string[] strRows = strRow.Split('*');

                //创建表
                if (tb == null)
                {
                    tb = new DataTable();
                    tb.TableName = strName;
                    foreach (string str in strRows)
                    {
                        var dc = new DataColumn();
                        string[] strCell = str.Split('#');

                        if (strCell[0].Substring(0, 1) == "\"")
                        {
                            int a = strCell[0].Length;
                            dc.ColumnName = strCell[0].Substring(1, a - 2);
                        }
                        else
                        {
                            dc.ColumnName = strCell[0];
                        }
                        tb.Columns.Add(dc);
                    }
                    tb.AcceptChanges();
                }

                //增加内容
                DataRow dr = tb.NewRow();
                for (int r = 0; r < strRows.Length; r++)
                {
                    dr[r] = strRows[r].Split('#')[1].Trim().Replace("，", ",").Replace("：", ":").Replace("\"", "");
                }
                tb.Rows.Add(dr);
                tb.AcceptChanges();
            }

            return tb;
        }

Answer 1

    DataTable dt2 = x.Copy();
            foreach (var t in x.Columns)
            {
                if(t.ToString()!= "L" && t.ToString() != "K")
                   dt2.Columns.Remove(t.ToString());
            }

            dataGridView1.DataSource = dt2;
