structure map with factory pattern using structuremap.config

I was looking for a very simple example around for integrating structure map with factory pattern , since I found it in bit and pieces.. I am here documenting my own version of it.


Before I  jump in to code and configuration the jist of below code is that, I would like to create Italian or Indian food object based on what customer request.

StructureMap.config -  make sure you set property Copy to out put directory as Copy always

feel free to download complete code from https://github.com/varunpathak/samples.git
 
 <?xml version="1.0" encoding="utf-8" ?>
<StructureMap>


  <PluginFamily Type="StructureMapHelloWorld.IFood" Assembly="StructureMapHelloWorld" DefaultKey="IndianFoodKey">
    <Plugin Type="StructureMapHelloWorld.SouthIndian" Assembly="StructureMapHelloWorld" ConcreteKey="IndianFoodKey" />
    <Plugin Type="StructureMapHelloWorld.Italian" Assembly="StructureMapHelloWorld" ConcreteKey="ItalianFoodKey" />
  </PluginFamily>



</StructureMap>


 FoodEngine.cs

namespace StructureMapHelloWorld
{
    
    public interface IFood
    {
        string GetFood();
    }

    public class SouthIndian : IFood
    {
        public string GetFood()
        {
            return "Idly-Dosa";
        }
    }

    public class Italian : IFood
    {
        public string GetFood()
        {
            return "Pizza";
        }
    }


}





Program.cs


using StructureMap;
using System;

namespace StructureMapHelloWorld
{
    class Program
    {
        static void Main(string[] args)
        {
            ConfigureDependencies();


            Console.WriteLine("Type indian for Indian food / type italian for Italian Food / Press E to Exit");

            string foodKind = Console.ReadLine();

            while (String.IsNullOrEmpty(foodKind) == false && foodKind.ToLower() != "e")
            {

                IFood food;

                if (foodKind.ToLower().Contains("italian"))
                {
                    food = ObjectFactory.GetNamedInstance<IFood>("ItalianFoodKey");
                    Console.WriteLine("Thanks for Ordering " + food.GetFood());
                    foodKind = Console.ReadLine();
                }

                else if (foodKind.ToLower().Contains("indian"))
                {
                    food = ObjectFactory.GetNamedInstance<IFood>("IndianFoodKey");
                    Console.WriteLine("Thanks for Ordering " + food.GetFood());
                    foodKind = Console.ReadLine();
                }

                else
                {
                    Console.WriteLine("Type indian for Indian food / type italian for Italian Food / Press E to Exit");
                    foodKind = Console.ReadLine();
                }


            }

            Environment.Exit(0);

        }


        private static void ConfigureDependencies()
        {
            
            ObjectFactory.Initialize(x =>
            {
                // We put the properties for an NHibernate ISession
                // in the StructureMap.config file, so this file
                // must be there for our application to
                // function correctly
                //http://docs.structuremap.net/ConfiguringStructureMap.htm
                x.UseDefaultStructureMapConfigFile = true;
                //x.PullConfigurationFromAppConfig = true;
            });

        }
    }
}

JSON Date input to WCF Rest service

what's the problem .....in passing date using ajax/JSON method to wcf rest service ,you can read it here ....from Scott and problem here

now you got to pass a date(JSON FORMAT) using ajax/JSON call from asp.net page. ,

I have taken bits of code and modified to my needs from here


using System;
using System.Collections.Generic;
using System.Runtime.Serialization;

namespace SomeNameSpace
{
/// <summary>
/// Class describes the Entities for Persons
/// </summary>
[DataContract(Namespace = "")]
public class Person
{
private int _personId;
private string _emailAddress;
private string _IP;
private DateTime _CreatedOn;
private DateTime _ModifiedOn;
private DateTime _subscribedOn;
private string _statusCD;
private string _sourceCD;


[DataMember]
public virtual int PersonId
{
get
{
return _personId;
}
set
{
_personId = value;
}
}
[DataMember]
public virtual string EmailAddress
{
get
{
return _emailAddress;
}
set
{
_emailAddress = value;
}
}
[DataMember]
public virtual string IP
{
get
{
return _IP;
}
set
{
_IP = value;
}
}
[DataMember]
public virtual DateTime CreatedOn
{
get
{
return _CreatedOn;
}
set
{
_CreatedOn = value;
}
}
[DataMember]
public virtual DateTime ModifiedOn
{
get
{
return _ModifiedOn;
}
set
{
_ModifiedOn = value;
}
}
/// <summary>
/// Gets or sets the subscriptione date.
/// </summary>
/// <value>
/// The subscribed on.
/// </value>
[DataMember]
public virtual DateTime SubscribedOn
{
get
{
return _subscribedOn;
}
set
{
_subscribedOn = value;
}
}
/// <summary>
/// Gets or sets the status cd.this is null when a user unsubscribes
/// </summary>
/// <value>
/// The status cd.
/// </value>
[DataMember]
public virtual string StatusCD
{
get
{
return _statusCD;
}
set
{
_statusCD = value;
}
}
/// <summary>
/// Gets or sets the source cd.To Identify whether a user is valid
/// </summary>
/// <value>
/// The source cd.
/// </value>
[DataMember]
public virtual string SourceCD
{
get
{
return _sourceCD;
}
set
{
_sourceCD = value;
}
}

}
}


                 [OperationContract()]
[WebInvoke(Method = "POST", UriTemplate = "AddUser")]
bool AddUser(Person user);



       
      [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, InstanceContextMode = InstanceContextMode.PerCall)]
public class TestService : ISubscriberService
{

       public bool AddUser(Person user)
{
            return true;
//Do what ever you want
}
    }


download ww.jquey.js from here

under your aspx page refer <script src="scripts/ww.jquery.js"></script>


<script type="text/javascript">

        var date = new Date();

        EmailAddress = 'varunpathak123@gmail.com';
        SourceCD = 'testapp';

       

        var person =
                        {
                            'IP': "12.22.434",
                            'CreatedOn': date,
                            'ModifiedOn': date,
                            'SubscribedOn': date,
                            'StatusCD': "ACTV",
                            'EmailAddress': EmailAddress,
                            'SourceCD': SourceCD,
                           
                        };







                        person = JSON.stringifyWcf(person);

        function PostData() {
            $.ajax(
                        {
                            type: "POST",
                            url: "http://localhost:9234/AddUser",
                            contentType: "application/json; charset=utf-8",
                            data: person,
                            dataType: "json",
                            success: function (result) {
                             
                                alert("Success");
                            },
                            failure: function (result) {
                                alert("Failure");
                            }
                        });
        }
                   

                 

    </script>

I want to give a vote of thanks again to Rick Strahl. There are plenty of post out there which I tried but did not work for me....apart from this one .
I could have changed my wcf service ,but dates have always been a problem be it any world.

I have highlighted the function JSON.stringifyWCF which looks like this

 JSON.stringifyWcf = function(json) {
        /// <summary>
        /// Wcf specific stringify that encodes dates in the
        /// a WCF compatible format ("/Date(9991231231)/")
        /// Note: this format works ONLY with WCF.
        ///       ASMX can use ISO dates as of .NET 3.5 SP1
        /// </summary>
        /// <param name="key" type="var">property name</param>
        /// <param name="value" type="var">value of the property</param>        
        return JSON.stringify(json, function(key, value) {
            if (typeof value == "string") {
                var a = reISO.exec(value);
                if (a) {
                    var val = '/Date(' + new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4], +a[5], +a[6])).getTime() + ')/';
                    this[key] = val;
                    return val;
                }
            }
            return value;
        })
    };

one can make out it is specifically targeting dates format.which is always a issue with JSON to WCF


I hope this post will help some one.

Add JQuery intellisense in Visual Studio

To do this all you got to do is Drag and drop the JQuery file in in the file you are looking to program using JQuery




That's all .Now its time to explore endless capabilities that JQuery provides.
