Question

我得到的是我的json结果，如下所示。我在数据中得到 Back Slashes 。

“[{\”Route No _ \“：\”1001 \“，\”Description \“：\”Testing \“，\”Duration \“：120，\”KM Coverage \“：100.00000000000000000000 ，“里程”：20.50000000000000000000，“免税额”：150.55000000000000000000，“修理和维护”：200.22000000000000000000}]“

我的代码是

    public string GetJSONDataForRouteInfo()
    {
        DataTable dt = new DataTable();
        using (SqlConnection con = new SqlConnection(@"Data Source=HITSEDGE\HITSEDGE;Initial Catalog=CCIL1;User ID=dbassist;Password=assist@123"))
        {
            using (SqlCommand cmd = new SqlCommand("select [Route No_],[Description],[Duration],[KM Coverage],[Mileage],[Allowance],[Repair And Maintenance] from dbo.[CRONUS International Ltd_$Route]", con))
            {
                con.Open();
                SqlDataAdapter da = new SqlDataAdapter(cmd);
                da.Fill(dt);
                System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();               
                List<Dictionary<string, object>> rows = new List<Dictionary<string, object>>();
                Dictionary<string, object> row;
                foreach (DataRow dr in dt.Rows)
                {
                    row = new Dictionary<string, object>();
                    foreach (DataColumn col in dt.Columns)
                    {
                        row.Add(col.ColumnName, dr[col]);
                    }
                    rows.Add(row);
                }

                serializer.Serialize(rows);

                string resultjson = serializer.Serialize(rows).Replace(@"\", "");
                return resultjson;
            }
        }
    }

我的界面是

[OperationContract]
    [WebGet(BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "GetJSONDataForCustmerinfo")]
    string GetJSONDataForCustmerinfo();

在这里，我尝试将'\'替换为双重代码'“'。我需要得到我的结果

[{“Route No _”：“1001”，“Description”：“Testing”，“Duration”：120，“KM Coverage”：100.00000000000000000000，“Mileage”：20.50000000000000000000，“Allowance”：150.55000000000000000000， “维修和保养”：200.22000000000000000000}]

如何得到这样的结果。

我替换了我的代码，但是结果相同。

 public string GetJSONDataForRouteInfo()
    {
        DataTable dt = new DataTable();
        using (SqlConnection con = new SqlConnection(@"Data Source=HITSEDGE\HITSEDGE;Initial Catalog=CCIL1;User ID=dbassist;Password=assist@123"))
        {
            using (SqlCommand cmd = new SqlCommand("select [Route No_] as Routeno,[Description],[Duration],[KM Coverage],[Mileage],[Allowance],[Repair And Maintenance] from dbo.[CRONUS International Ltd_$Route]", con))
            {
                con.Open();
                SqlDataAdapter da = new SqlDataAdapter(cmd);
                da.Fill(dt);                
                string json = string.Empty; ;
                json = JsonConvert.SerializeObject(dt);


                string outputjson = json.Replace("\\", "");


                return outputjson;
            }
        }
    }

以这种方式尝试

public string GetJSONDataForRouteInfo()
    {
        DataTable dt = new DataTable();
        using (SqlConnection con = new SqlConnection(@"Data Source=HITSEDGE\HITSEDGE;Initial Catalog=CCIL1;User ID=dbassist;Password=assist@123"))
        {
            using (SqlCommand cmd = new SqlCommand("select [Route No_] as Routeno,[Description],[Duration],[KM Coverage],[Mileage],[Allowance],[Repair And Maintenance] from dbo.[CRONUS International Ltd_$Route]", con))
            {
                con.Open();
                SqlDataAdapter da = new SqlDataAdapter(cmd);
                da.Fill(dt);  
                System.Web.Script.Serialization.JavaScriptSerializer serializer = new    System.Web.Script.Serialization.JavaScriptSerializer();
                List<Dictionary<string, object>> rows = new List<Dictionary<string, object>>();
                Dictionary<string, object> row;
                foreach (DataRow dr in dt.Rows)
                {
                   row = new Dictionary<string, object>();
                   foreach (DataColumn col in dt.Columns)
                   {
                     row.Add(col.ColumnName, dr[col]);
                   }
                   ws.Add(row);
                 }
                  return serializer.Serialize(rows);                    
            }
        }
    }

如果您可以使用Json.NET，则可以执行以下操作

string json = JsonConvert.SerializeObject(dt, Formatting.Indented);

Json的结果是反斜杠
