Nested Ananymous function - real world sample

its been since few of my friends were behind me for Nested ananymous functions real life sample, due to busy consulting hours and work pressure, i couldnt post this.

here u go guys ..............

copy the entity files

using System;

using System.Collections.Generic;

using System.Text;

namespace TestHarness

{

public class MenuItem

{

private int menuID;

public int MenuID

{

get { return menuID; }

set { menuID = value; }

}

private string menuText;

public string MenuText

{

get { return menuText; }

set { menuText = value; }

}

private string description;

public string Description

{

get { return description; }

set { description = value; }

}

private string url;

public string Url

{

get { return url; }

set { url = value; }

}

private int moduleID;

public int ModuleID

{

get { return moduleID; }

set { moduleID = value; }

}

public MenuItem(int menuid, string menutext, string description, string url, int moduleid)

{

this.menuID = menuid;

this.menuText = menutext;

this.description = description;

this.url = url;

this.moduleID = moduleid;

}

}

}

-------------------------------------

using System;

 

using System.Collections.Generic;

 

using System.Text;

 

namespace TestHarness

{

public class ProductKeys

 

{

private int key;

public int Key

{

get { return key; }

set { key = value; }

}

private int value;

public int Value

{

get { return this.value; }

set { this.value = value; }

}

public ProductKeys(int key, int value)

{

this.key = key;

this.value = value;

}

}

}

---------------------------------

using System;

 

using System.Collections.Generic;

 

using System.Text;

 

namespace TestHarness

{

public class UserPermissions

 

{

private int key;

private int value;

public UserPermissions(int key, int value)

{

this.key = key;

this.value = value;

}

public int Key

{

get { return key; }

set { key = value; }

}


public int Value

{

get { return this.value; }

set { this.value = value; }

}


}

}

-----------------------------------

create factoty methods to populate data

using System;
using System.Collections.Generic;
using System.Text;

namespace TestHarness

{

public class MenuFactory

{

public List<MenuItem> GetMenus()

{

List<MenuItem> menus = new List<MenuItem>();

menus.Add(new MenuItem(1, "Organisation", "", "", 1));

menus.Add(new MenuItem(2, "Persons", "", "", 2));

menus.Add(new MenuItem(3, "Accounts", "", "", 3));

menus.Add(new MenuItem(4, "Bookings", "", "", 4));

menus.Add(new MenuItem(5, "Delegates", "", "", 5));

menus.Add(new MenuItem(6, "Course", "", "", 6));

menus.Add(new MenuItem(7, "Elements", "", "", 7));

menus.Add(new MenuItem(11, "Accmodations", "", "", 8));

menus.Add(new MenuItem(14, "Reports", "", "", 9));

menus.Add(new MenuItem(15, "Help", "", "", 10));

return menus;

}

}

}

---------------------------------------

using System;

 

using System.Collections.Generic;

 

using System.Text;

 

namespace TestHarness

{

public class ProductKeyFactory

 

{

public List<ProductKeys> GetProductKeys()

{

List<ProductKeys> productkeys = new List<ProductKeys>();


productkeys.Add(new ProductKeys(1,1));

productkeys.Add(new ProductKeys(2, 1));

productkeys.Add(new ProductKeys(3, 1));

productkeys.Add(new ProductKeys(4, 1));

productkeys.Add(new ProductKeys(5, 1));

productkeys.Add(new ProductKeys(6, 0));

productkeys.Add(new ProductKeys(7, 1));

productkeys.Add(new ProductKeys(8, 1));

productkeys.Add(new ProductKeys(9, 1));

productkeys.Add(new ProductKeys(10, 0));


return productkeys;

}

}

}

-----------------------------------------

using System;

 

using System.Collections.Generic;

 

using System.Text;

 

namespace TestHarness

{

public class UserPermissionFactory

{

public List<UserPermissions> GetUserPermissions()

{

List<UserPermissions> permissions = new List<UserPermissions>();

permissions.Add(new UserPermissions(1, 9));

permissions.Add(new UserPermissions(2, 0));

permissions.Add(new UserPermissions(3, 3));

permissions.Add(new UserPermissions(4, 9));

permissions.Add(new UserPermissions(5, 9));

permissions.Add(new UserPermissions(6, 1));

permissions.Add(new UserPermissions(7, 9));

permissions.Add(new UserPermissions(8, 9));

permissions.Add(new UserPermissions(9, 9));

permissions.Add(new UserPermissions(10, 9));

return permissions;

}

}

}

 


Testharness -- to test

 

using System;
using System.Collections.Generic;
using System.Text;

namespace TestHarness

{

class Program


{

static void Main(string[] args)

{

List<MenuItem> menuItems = new List<MenuItem>(new MenuFactory().GetMenus());

List<ProductKeys> productKeys = new List<ProductKeys>(new ProductKeyFactory().GetProductKeys());

List<UserPermissions> userPermissions = new List<UserPermissions>(new UserPermissionFactory().GetUserPermissions());

int result = 0;

Console.WriteLine(menuItems.FindAll(new Predicate<MenuItem>(delegate(MenuItem mItem)

{

UserPermissions isExist = userPermissions.Find(new Predicate<UserPermissions>

(delegate(UserPermissions permissions)

{

if (permissions.Key == mItem.ModuleID && permissions.Value > 0)

{

return true;

}

return false;

}));

if (null != isExist)

result = isExist.Key;

return mItem.ModuleID == result;

})).Count);

Console.ReadLine();


}

}

}

 

I will give a little more insight tomorrow on ananymous functions and there usage on real time applications..

and gonna post loads of stuff during christmas on design patterns and biztalk ... keep a little eye on my blog :-)
