字符串转JSON

因为form_component_values里的详情返回的不是JSON格式，需要转义

要提取报销金额，承担部门等

 

string strcdbm = listValueVO[1].Value.ToString(); //承担部门编码(费用所属院区)

                    string strbxsm = listValueVO[0].Value;//报销说明.这个listValueVO[0]就是form_component_values节点
                    JArray jarry = (JArray)JsonConvert.DeserializeObject(strbxsm);
                    //JArray jarry = JArray.Parse(jo["rowValue"].ToString());
                    string thisid = "1";//分录ID
                    string parentId = business_id;//主表Id

                    for (var i02 = 0; i02 < jarry.Count; i02++)
                    {
                        JObject j = JObject.Parse(jarry[i02].ToString());

                        JArray jarry1 = JArray.Parse(j["rowValue"].ToString());
                        JObject jk0 = JObject.Parse(jarry1[0].ToString());//报销金额0.12
                        JObject jk1 = JObject.Parse(jarry1[1].ToString());//承担部门编码150867735
                        JObject jk3 = JObject.Parse(jarry1[3].ToString());//费用项目编码，名称办公费

                        string thisAmount = jk0["value"].ToString();//报销金额
                        string payDepart = jk1["extendValue"].ToString();//承担部门编码
                        payDepart = payDepart.Substring(payDepart.IndexOf("id")+2);
                        payDepart = payDepart.Replace("\"", "").Replace(":", "").Replace("}", "").Replace("]", "").Replace(" ", "");
                        string costItem = jk3["value"].ToString();//费用项目编码
                                                                  //for (var k = 0; k < jarry1.Count; k++)
                                                                  //{
                                                                  //    //JObject jk = JObject.Parse(jarry1[k].ToString());
                                                                  //}
                        string a03 = "";
                    }

                    string a02 = "";
