String.Split On Steroids

The String.Split function uses a separator to divide a string value into an array of string values. Unfortunately the split function does not support text qualifiers. As a result, if the separator is contained within a text qualified block of characters, the text block gets split.

In this article we will create a new extension called, FullSplit, that will implement the same basic functionality of the String.Split function with the added support of text qualifiers and assignment operators. When assignment operators are used the return value will be of type StringDictionary where the left side of the operator represents the DictionaryEntry.Key property and the right side represents the DictionaryEntry.Value property.

Finally we will conclude the article by updating the code from a previous post, Extending IEnumerable, to support dictionary entries by separating the key/value pair with an operator.

Extending IEnumerable

Often there is the need to take a string value and split it into an array of values. String.Split provides a quick and convenient method to split strings (as long as you don’t have to worry about text qualifiers). Today I ran into the opposite scenario. I needed to combine the different iterations of an array into a single string value.

Immediately my mind turned to extensions. A beautiful, simple and elegant solution.
