split

I'd like to do a Regex.Split on some separators but I'd like to keep the separators. To give an example of what I'm trying:

"abc[s1]def[s2][s3]ghi" --> "abc", "[s1]", "def", "[s2]", "[s3]", "ghi"

The regular expression I've come up with is new Regex("\\[|\\]|\\]\\["). However, this gives me the following:

"abc[s1]def[s2][s3]ghi" --> "abc", "s1", "def", "s2", "", "s3", "ghi"

The separators have disappeared (which makes sense given my regex). Is there a way to write the regex so that the separators themselves are preserved?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
