The following classes have been extended:

with these methods:

• BeginsWith()

  Checks if the current string begins with the given target string.
  For example:
  "GCCHigh.Extensions rock!".BeginsWith("GCCHigh")
  will return
  true
  whereas
  "GCCHigh.Extensions rock!".BeginsWith("gcchigh")
  will also return
  true
  because the ignorecase switch defaults to true. Using the
  ignorecase switch like this
  "GCCHigh.Extensions rock!".BeginsWith("gcchigh", false)
  will return
  false
  

• ContainsAny()

  Checks if the given string contains any of the characters or strings
  provided in the IEnumerable.
  This is useful for validating a given set of characters, like
  special characters, or a given set of string, like bad words, is
  not present in the target string.
  

• ContainsOnly()

  Checks if the given string contains only the characters or strings
  provided in the IEnumerable.
  This is useful for validating a string contains only hex chars etc.
  

• DoubleQuote()

  Return the given string encased in double quotes. This is useful
  when working with multi-layer quotes and strings where strings
  contain quoted strings.
  

• EncodeAsXml()

  Encode a given string as XML by encoding all ampersand, single
  quote, greater than, less than and double quote characters into
  their proper XML equivalent.
