TypeExtensionsRegisterConversion Method (Type, Type, ConversionAttempt)

public static void RegisterConversion(
	this Type sourceType,
	Type targetType,
	ConversionAttempt conversion
)

<ExtensionAttribute>
Public Shared Sub RegisterConversion ( 
	sourceType As Type,
	targetType As Type,
	conversion As ConversionAttempt
)

public:
[ExtensionAttribute]
static void RegisterConversion(
	Type^ sourceType, 
	Type^ targetType, 
	ConversionAttempt^ conversion
)

[<ExtensionAttribute>]
static member RegisterConversion : 
        sourceType : Type * 
        targetType : Type * 
        conversion : ConversionAttempt -> unit 

Parameters

sourceType

Type: SystemType
The source Type for which the conversion can be called.

targetType

Type: SystemType
The result Type that conversion produces.

conversion

Type: KGySoft.CoreLibrariesConversionAttempt
A ConversionAttempt delegate, which is able to perform the conversion.

Usage Note

After calling this method the Convert/TryConvert Object extension methods and Parse/TryParse String extension methods will be able to use the registered conversion between sourceType and targetType.

Calling the RegisterConversion methods for the same source and target types multiple times will override the old registered conversion with the new one.

Tip
The registered conversions are tried to be used for intermediate conversion steps if possible. For example, if a conversion is registered from Int64 to IntPtr, then conversions from other convertible types become automatically available using the Int64 type as an intermediate conversion step.

sourceType and targetType can be interface, abstract or even a generic type definition. Preregistered conversions:

• KeyValuePairTKey, TValue to another KeyValuePairTKey, TValue
• KeyValuePairTKey, TValue to DictionaryEntry
• DictionaryEntry to KeyValuePairTKey, TValue
• IEnumerableT of char to IEnumerableT of Rune (.NET Core 3.0 and above)
• IEnumerableT of Rune to IEnumerableT of char (.NET Core 3.0 and above)
