Creating classes and extension methods in LINQPAD

A very good thing to know is that you can actually define your own classes in LinqPad. The trick to it is that you must put a closing bracket to the linqpad code and start your class, but omit the last bracket.

This post explains why.

Interacting with Iframes using Javascript

// reference to iframe with id 'ifrm'

var ifrm = document.getElementById('ifrm');

// reference to window in the iframe
var win = ifrm.contentWindow;

// reference to document in iframe
var doc = ifrm.contentDocument? ifrm.contentDocument: ifrm.contentWindow.document;

// reference to a form named 'ifrmTest' in iframe
var form = doc.getElementById('ifrmTest');

Best practices for estimating projects & satisfied customers

* Components of a project (notes from 1/28/2012)

• Customers
• Requirements
• Estimated time
• Estimate a project and communicate any changes to the plan.
• Elapsed hours
• Actual time
• You must track your actual time and compare it to estimated time 

• You are still on track if you spend more time, but explained to customers what's happening.
• this is how you schedule estimated hours

* Completely satisfied customers

Ask customers if they are completely satisfied, not just if they are satisfied. If they are not completely satisfied, ask what can we do to make you completely satisfied.

Linq SelectMany and GroupJoin to do a join

Here's how to do a join between two arrays in a Linq Lambda expression:

var list1 = new int[] {1,2,3,4,5};
var list2 = new int[] {2,3};
var result = list1.SelectMany(l2=>list2, (l1,l2)=>new {l1,l2, sum=l1+l2})
.Where (x=>x.l1==x.l2)
.Select(x=> x); 

The result is this:

And now here is the GroupJoin version which actually does a nice left join:

 
var groupJoinResult = list1
 .GroupJoin(list2, 
  L1=>L1,
  L2=>L2,
  (l1, l2) => new {l1,l2}).Dump();

The result is this:

And finally to do a left join, use DefaultIfEmpty qualifier in inner query of select many, as shown in this stackoverflow q and a.
