| Description |
The Split method is intended to work as a simple string parser. It scans for separating characters, extracting the text either side of the separator into substrings.
The number of substrings can be limited by the Count parameter.
For example, the following string :
Age=47;Name=Neil;Occupation=Programmer
Can be parsed first using ';' as the separator character to give :
Age=47
Name=Neil
Occupation=Programmer
And then each of these can be parsed using the '=' separator character.
Or the original string can be parsed in one go by providing both the ';' and '=' characters in the character array parameter.
the second example illustrates this parsing in one run of split. Be careful doing this in one go - it makes the process more error prone!
