我认为您应该使用Web API。在https://docs.microsoft.com/en-us/aspnet/web-api/overview/getting-started-with-aspnet-web-api/using-web-api-with-aspnet-web-forms

if (user != null)
    {
        if (user.type != null && user.user != null && user.pass != null)
        {
            SqlConnection con = new SqlConnection(str);
            SqlCommand cmd = new SqlCommand();
            cmd.Connection = con;
            cmd.CommandText = "SELECT ID,UserName From Partner ";
            //Where UserName=@UserName And PassWord=@Pass
            //cmd.Parameters.Add("@UserName", SqlDbType.VarChar, 100).Value = user.user;
            //  cmd.Parameters.Add("@Pass", SqlDbType.NVarChar, 100).Value = user.pass;
            if (ConnectionState.Closed == con.State)
                con.Open();
            SqlDataAdapter sqlDataAdapter = new SqlDataAdapter(cmd);
            con.Close();
            sqlDataAdapter.Fill(datatable);
            int i = 0;
            if (datatable.Rows.Count > 0)
            {
                foreach (DataRow dr in datatable.Rows)
                {
                    json += "A" + i + ":{ID:'" + dr["ID"] + "',User:'" + dr["UserName"] + "'},";
                    i++;
                }
                json = json.Remove(json.Length - 1);
                json += "}";
                JObject json2 = JObject.Parse(json);
                context.Response.Write(json2);
                return;

            else

        JObject json3 = JObject.Parse(json);
