May at the Israel C# user group: Advanced Use of Delegates and Generics

Earlier this month, My friend Oren Ellenbogen contacted me saying he'd like to do a talk in one of the upcoming user groups here in Israel about .NET about the advanced used of delegates and generics in .NET applications.

I referred him to the C# and VB user groups and surely enough, he'll be speaking at the upcoming C# user group meeting next month.

 

(speaking of user groups, a little bird tells me that a new user group is forming in Israel, for development managers. Shhh. you'll here more in the coming months)

 

I recommend VB.NET developers who know how to read C# code go just as well. It's all the same underneath the covers anyway..

Here's the excerpt from the group site (it's free to just show up, BTW)

Topic: Advanced Use of Delegates and Generics

Lecturer: Oren Ellenbogen

 This lecture will not be just about Delegates or Generics, but it will combine those topics to show you how you can leverage to usability of those semi-new features. Oren will discuss the receiving of delegates as parameters and the implementation of abstraction in this methodology. He will tie the two topics together by refactoring(live!) existing code using a principle he calls “Code Templating”;  a coding method that allows running unique logic within recurrent code.

 Agenda:

1. Looking at a "simple" scenarios of recurrent code
   1. Check if a value exists in a collection.
   2. Get the item index in a collection.
   3. Filtering a collection (get only some of the items based on a condition).
   4. Manipulating every item in the collection (string concatenation for example).
2. Looking at "advanced" scenarios of recurrent code
   1. Querying the database.
   2. Exception handling.
3. Discuss solutions for further abstraction in those scenarios.
4. Introduce "Code Templating" – separating the unique code from the recurrent code.
5. Before we start, getting to know our toolbox: generics & delegates
   1. What are they?
   2. Calling a delegate which was given as parameter – understand the benefits.
   3. Anonymous delegates\methods – how & why
   4. What's going on under the hood?
6. Examples of Code Templating in .Net 2.0
   1. Handle those "simple" scenarios via List<T>.Find, List<T>. FindAll, List.<T>.Exists etc…
7. Refactor (live!) the "advanced" scenarios, step-by-step.
8. Code Templating - What do we gain? What can we lose?
9. Q & A
