Removing item from dictionary in C#

  There is a method aptly named Remove:

  public bool Remove

  (
 TKey key
  )

  dict.Remove(keyId)

 It will not raise the exception if key does not exist -  handy!

  If you do want to check existence of the key anyways, it will return false if it  is unable to find a key (or unable to remove it for some other odd reason).
