• 12thFret Should StreamWriter Auto-Close in Destructor?

  Hi all, This is a newbie question... I have a StreamWriter that writes some text to a file.

  The ".IndexOf" functionality for determining the position of a char within a string is very useful, but I need to be able to do a similar thing with a string rather than a char. i.e. I would like to be able to say string1.IndexOf("string2") rather than just string1.IndexOf('c'). Is there simple functionality like this that I don't know about (or have just plain forgotten!) If not, what is the recommended strategy ...Show All
