The above method calls for using the SavingChanges event which is called before the changes are persisted. If there is an error during the save, you have already cleared your dirty flag. I would think there would be a SavedChanges event exposed as well. |
You can generate data plans with VSTS Database Edition (with the latest 2008 Power tools).

No I wish there was but the programming effort seems too much since there are multiple ways to reference a single element. The best that you can do is use a runtime like FireBug to find duplicates. |
I've always gone the string.Format() route. Being able to store formats in variables like Nathan's example is a great advantage. In some cases I may append a variable but once more than 1 variable is being concatenated I refactor to use formatting. |

What you need to do is determine the ordering of B and then apply that ordering to A. One way to accomplish this is to undo the ordering of B and keep track of what happens along the way. Then you can do the reverse to A.

From MSDN:
"The CompareTo method was designed primarily for use in sorting or alphabetizing
operations. It should not be used when the primary purpose of the method call is to
determine whether two strings are equivalent. To determine whether two strings are
equivalent, call the Equals method."

In the forms you listed here, there's not much difference between the two. <code>CompareTo</code> ends up calling a <code>CompareInfo</code> method that does a comparison using the current culture; <code>Equals</code> is called by the <code>==</code> operator.

> @ Konrad: So how do you use it? Let's say I want to match mo.ID to magicNumber.
In C# 2.0 you'd write:
result = mObjList.Find(delegate(int x) { return x.ID == magicNumber; });
3.0 knows lambdas:
result = mObjList.Find(x => x.ID == magicNumber); |
Using a Lambda expression:
List<MyObject> list = new List<MyObject>();
// populate the list with objects..
return list.Find(o => o.Id == myCriteria); |
Well I guess you have to be rather particular about it, but like people are saying, it makes more sense for String.Format to be static because of the implied semantics. Consider:

It depends on how you're reading and writing the XML.
If XML is being generated automatically - if newlines or explicit **\n** flags are being parsed into **<br />** - then there's nothing to worry about. Your input likely doesn't have any other XML in it so it's just cleaner to not mess with XML at all.
