A utility library for .Net

Shared.Utilities

A library made up of various small utility functions/classes. The library also contains some experimental stuff that I've been toying round with.

Library contains:

• Generic and Projected comparers that take lambda functions for the comparison operations
• Data structures
  • Bloom filter
  • Counting bloom filter
  • Trie (Prefix tree)
• Custom attribute and resolver class to allow enumeration values to be marked with descriptions
• Extension methods
  • NameValueCollection extensions
  • DataSet extensions to determine whether or not a DataSet is populated
  • Func extensions to allow a Func delegate to be automatically retried a specified number of times
  • Log4Net extensions to allow easier logging of function arguments and exceptions
  • Primitive extensions
    • DateTime
      • Move a DateTime to the start/end of the day
      • Convert DateTime to a file system safe string
      • Convert to Unix Time
    • Event extensions for more convenient event raising
    • Exception extensions to flatten an Exception hierarchies error messages/stack trace string
    • Reflection extensions that allow easier access to a members custom attribute metadata
    • IComparable extensions for IsOdd/IsEven/Between
    • Random extensions for generating random strings
    • StringBuilder
      • StartsWith
      • EndsWith
      • Contains
      • SubString
    • String
      • Contains/Equals ignoring case
      • Levenshtein distance
      • Format
      • Hash (using any supplied hashing algorithm)
      • Pad
      • RemoveLeadingCharacters
      • Wrap (on word boundaries to make outputting to the console easier)
  • Serialization extension methods to allow any object to be serialized/deserialized using the supplied serialization providers
• Functional (experimental)
  • Curry/Uncurry
  • Y Combinator
• Common regular expression matching functions
• Security
  • HMAC One Time Password (RFC4226) for use in two factor authentication
  • Time-based One Time Password (RFC6238) for use in two factor authentication
• SerializationProviders that wrap all of the default .Net serializers (BinaryFormatter, DataContractSerializer, DataContractJsonSerializer, XmlSerializer) and provide a common interface for serializing/deserializing
• Threading
  • ThreadRunner class to run a delegate on a thread in a specific apartment (STA/MTA).
  • ThreadShared and Padlock which allow a thread shared resource to be associated with it's lock. If the resource is accessed outside of it's lock then an exception is generated.
• ConvertEx - Alternative to System.Convert that will return Nullable if the value cannot be converted
• Insist - A whole set of assert functions. Useful for validating preconditions on method entry.
• Maybe - Implementation of the Maybe monad.
• NonNullable - Provides the opposite functionality to Nullable in that it prevents a null reference.
• OperationResult - Generic class for returning success/failure information from a method
• Retry - Allows a delegate to be automatically retried upon failure
• StaticRandom - Thread-safe static class for random number generation.
