SystemExtension Project

The first related project is System.Extension. This is an extension of the classes included in Frawework 2.0. It will contains lot of common used, open source classes and methods. Their implementations are normally inherited from the originals.

I'm working in the very first version implementing Default Format, a way to change the behavior of ToString(), adding an array of format rules. This will give you the chance to control how variables are displayed. For me, it is very usefull rendering GridViews.

Some rules implemented are:

MaxLenghtRule(int MaxLenght)
NullRule(string default)
NumericRule(enum StandardNumericFormat, int? decimals)
ToLowerRule()
ToUpperRule()
TrimRule()

For example:

StringExt text = new StringExt(" long text ");
text.DefaultFormat = new System.Format.IFormatRule[] { new System.Format.NullRule(" null "), new System.Format.TrimRule(), new MaxLengthRule(10, true), new ToUpperRule() };

The result of text.ToString() is: "long te..."

I will be checking projects like NetExtension, ApplicationBlocks, BlogEngine and PublicDomain to adopt common used methods. Your code snippets are welcome!!!
