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
```csharp
TypeConvert.Convert<int, ConsoleColor>(1) // DarkBlue
```	
Convert from string to IPAddress
```csharp
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
```csharp
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)

Release Notes

# 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

# braking 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
