hello,
Bellow is My Web Service written in C#.
In this, I got a return value and a table from database.
I want to merge it into single JSON Object/Array. How can I do it..?

con.Open();
        SqlDataAdapter da = new SqlDataAdapter("UpdateUserInfo2 ", con);
        da.SelectCommand.CommandType = CommandType.StoredProcedure;
        da.SelectCommand.Parameters.Add("@UserAutoId", SqlDbType.VarChar).Value = UserAutoId;
        da.SelectCommand.Parameters.Add("@userId", SqlDbType.VarChar).Value = userId;
        da.SelectCommand.Parameters.Add("@firstName", SqlDbType.VarChar).Value = fname;
        da.SelectCommand.Parameters.Add("@lastName", SqlDbType.VarChar).Value = lname;
        da.SelectCommand.Parameters.Add("@emailadr", SqlDbType.VarChar).Value = email;
        da.SelectCommand.Parameters.Add("@hieght", SqlDbType.VarChar).Value = hieght;
        da.SelectCommand.Parameters.Add("@retValue", System.Data.SqlDbType.Int).Direction = System.Data.ParameterDirection.ReturnValue;
        da.Fill(tbl);

        int retval = (int)da.SelectCommand.Parameters["@retValue"].Value;
        if (retval == 1)
        {
            string result = "1";

//Here I want to merge table Object(tbl) and return value (result)

            json = new JavaScriptSerializer().Serialize(result);
        }
        else if (retval == 2)
        {
            string result = "2";
            json = new JavaScriptSerializer().Serialize(result);
        }
        con.Close();
        return "json";
    }

What I have tried:

I trying to update single record on database and in response to query fetch, I want to get updated table and return value(or any object).

Why is "json" in quotes? it will return it as a literal (text) not as a json string.

You can create a class for your table columns

public class UserInfo
    {
        public string UserAutoId { get; set; }
        public string userId { get; set; }
        public string firstName { get; set; }
        public string lastName { get; set; }
        public string emailadr { get; set; }
        public string hieght { get; set; }
    }

then select the updated row. You can then serialize your class object.

con.Open();
SqlCommand cmd = new SqlCommand(selectQuery, con);
SqlDataReader reader = cmd.ExecuteReader();
UserInfo userInfo = new UserInfo();
while(reader.Read())
{
info.UserAutoId = reader["UserInfoAutoId"].ToString();
.
.
.

}

//now you can serialize the object
string userJson = ...

From return Table From SP

then

Java

JSONArray obj = new JSONArray();
    try {
         for(int i = 0; i <table.rows.count; i++) {
            // 1st object
            JSONObject list1 = new JSONObject();
            list1.put("val1",i+1);
            list1.put("val2",i+2);
            list1.put("val3",i+3);
            obj.put(list1);
         }
    } catch (JSONException e1) {
        // TODO Auto-generated catch block
      e1.printStackTrace();
    }

    Toast.makeText(MainActivity.this, ""+obj, Toast.LENGTH_LONG).show();
