Introduction
For historical reasons, .NET has several approaches to value conversion:
- Explicit/Implicit operators
- System.Convert class
- IConvertible interface
- System.ComponentModel.TypeConverter
- To, From, Parse, Create methods
- Constructors (Uri, Guid)
- Meta types(Enums, Nullable Types).
TypeConvert combines all these approaches under one API. Additionally this package has hexadecimal conversion API and type instancing API(cached for better perfomance). Each utility class in this package can be used separately and you are free to embedd them into your project.
TypeConvert
// generic
ToType Convert<FromType, ToType>(value, [format], [formatProvider]);
bool TryConvert<FromType, ToType>(value, out result, [format], [formatProvider])
string ToString<FromType>(value, [format], [formatProvider]);
// non-generic
object Convert(value, toType, [format], [formatProvider]);
bool TryConvert(ref value, toType, [format], [formatProvider]);
string ToString(value, [format], [formatProvider]);
TypeActivator
object CreateInstance(type, forceCreate = false);
object CreateInstance<Arg1T, ...>(type, arg1 ...);
HexConvert
string ToString(buffer, offset, count); // bytes -> hex
byte[] ToBytes(hexString, offset, count); // hex -> bytes
void Encode(buffer, offset, count, hexBuffer, hexBufferOffset); // bytes chunk -> hex chunk
void Decode(hexBuffer, offset, count, buffer, bufferOffset); // hex chunk -> bytes chunk
int WriteTo(number, hexBuffer, offset); // number -> hex
Number ToNumber(hexBuffer, offset) // hex -> number
Installation
Install-Package TypeConvert
Examples
TypeConvert
Convert from string to integer
TypeConvert.Convert<string, int>("1") // 1
Convert from integer to Enum
TypeConvert.Convert<int, ConsoleColor>(1) // DarkBlue
Convert from string to IPAddress
TypeConvert.Convert<string, IPAddress>("127.0.0.1") // 127.0.0.1 via IPAddress.Parse
Convert to string with format(if supported)
TypeConvert.ToString(1000000, format: "x") // f4240
Convert from any to IpAddress
TypeConvert.Convert("127.0.0.1", typeof(IPAddress)); 127.0.0.1 via IPAddress.Parse
Testing conversion
TypeConvert.TryConvert<string, int>("xxx", out intValue) // false
TypeActivator
Creating from default constructor
TypeActivator.CreateInstance(typeof(int)); // 0
Getting class instance without default constructor
TypeActivator.CreateInstance(typeof(EventArgs)); // via EventArgs.Empty
Getting class instance without default constructor and Empty property
TypeActivator.CreateInstance(typeof(IPEndPoint), force: true); // IPEndPoint bypassing constructor
Creating an array
TypeActivator.CreateInstance(typeof(int[])); // int[0] (same instance every time)

# 2.1.6
- fixed 'by-ref-like' parameter errors from .NET 5.0
# 2.1.5
- added case-insensitive EnumHelper.Parse overloads
- fixed: Uri -> string conversion should use Uri.Original string instead of Uri.ToString()
- fixed: HexConvert.ToString(buffer, offset, count) dont respect count parameter
- fixed: HexConvert.ToBytes(hexBuffer, offset, count) dont respect count parameter
- fixed: `Unable to cast object of type 'System.Linq.EmptyPartition1[System.TypeConvert+ConvertMethodInfo]' to type 'ConvertMethodInfo[]'` due breaking change in .NET 3.0
# 2.1.4
- added TypeConvert.RegisterCustomConversion method that allow override conversion operation between selected types.
- fixed Uri conversion. Relative url is now supported.
# 2.1.3
- fixed conversion methods (ToXXX, FromXXX) on value types cause delegate binding exception
# 2.1.2
- added netstandard2.0 and netcoreapp2.1 target platform
- fixed error with netcoreapp2.1 ByRefLike types (they are not supported in conversion operations)
- fixed error with string->enum conversion (new tests are added)
# 2.1.0
- added conversion via constructor support
- added System.ComponentModel.TypeConverter support for netstandard2.0 platform
# 2.0.0
- added fast conversion for numbers (byte, int, float...)
- added priority of conversion methods (formattable methods, implicit operators, explicit operators, Parse/Create/From/To methods, System.Convert methods)
- optimized performance by cutting redundant initialization of internal classes
- added documentation
# breaking changes
- non-generic Convert and TryConvert signature has been changed. Parameter "fromType" has been removed. Order of parameters has been changed.
- new priority of conversion methods could lead to conversion result that differs from v1.2.0.
- TypeConvert.ToString now returns String.Empty instead of null when null value is passed.
- changed signature of HexConvert's methods for better semantic
# 1.2.0
- fixed error in type activator parameters binding (now more specific types binds successfully)
- added new EnumHelper enum's properties DefaultValue, MinValue, MaxValue, Names, Values, UnderlyingType
- added forth argument to TypeActivator.CreateInstance methods
- TypeActivator signature fix to match .NET 4.5 and .NET Standard 1.3/2.0 build targets
# 1.1.0
- added EnumHelper for enum conversion between number and object form
- added '.NET Standard 1.3' platform target
# 1.0.0.1
- fixed object <-> nullable value, enum <-> nullable conversions
