TargetType

abstract

Gets the Type to that an object is mapped using this OpcDataTypeMapper.

public abstract Type TargetType { get; }

Public MustOverride ReadOnly Property TargetType As Type

Methods

Convert

Converts the sourceobject to a specific type.

public object Convert(object source, IFormatProvider provider)

Public Function Convert(source As Object, provider As IFormatProvider) As Object

Parameters

Name	Type	Description
source	Object	The sourceobject to convert.
provider	IFormatProvider	The IFormatProvider to control any formatting which may be necessary for the convertion.

Returns

Object

The converted object determined through the sourceobject and the provider specified.

Implements

Convert

ConvertBack

Converts the targetobject to the type from which the value has been created.

public object ConvertBack(object target, IFormatProvider provider)

Public Function ConvertBack(
    target As Object,
    provider As IFormatProvider) As Object

Parameters

Name	Type	Description
target	Object	The targetobject to convert back.
provider	IFormatProvider	The IFormatProvider to control any formatting which may be necessary for the convertion.

Returns

Object

The source object from which target has been created.

Implements

ConvertBack

ConvertBackCore

protected · abstract

When implemented in a derived class; converts the targetobject to the type from which the value has been created.

protected abstract object ConvertBackCore(
    object target,
    IFormatProvider provider)

Protected MustOverride Function ConvertBackCore(
    target As Object,
    provider As IFormatProvider) As Object

Parameters

Name	Type	Description
target	Object	The targetobject to convert back.
provider	IFormatProvider	The IFormatProvider to control any formatting which may be necessary for the convertion.

Returns

Object

The source object from which target has been created.

Remarks

This method is only used in case there target is not a null reference (Nothing in Visual Basic).

ConvertCore

protected · abstract

When implemented in a derived class; converts the sourceobject to a specific type.

protected abstract object ConvertCore(object source, IFormatProvider provider)

Protected MustOverride Function ConvertCore(
    source As Object,
    provider As IFormatProvider) As Object

Parameters

Name	Type	Description
source	Object	The sourceobject to convert.
provider	IFormatProvider	The IFormatProvider to control any formatting which may be necessary for the convertion.

Returns

Object

The converted object determined through the sourceobject and the provider specified.

Remarks

This method is only used in case there source is not a null reference (Nothing in Visual Basic).

Convertible

static

Provides an OpcDataTypeMapper which utilizes the IConvertible interface implemented by the TSource and TTarget types.

public static OpcDataTypeMapper Convertible<TSource, TTarget>()
    where TSource : IConvertible
    where TTarget : IConvertible

Public Shared Function Convertible(Of TSource As IConvertible, TTarget As IConvertible)() As OpcDataTypeMapper

Type parameters

Name	Description
TSource	The Type implementing the IConvertible interface and which is to be mapped to the TTarget type.
TTarget	The resulting Type (implementing the IConvertible interface) after mapping an object of the TSource type.

Returns

OpcDataTypeMapper

An instance of the OpcDataTypeMapper class utilizing the IConvertible implementations of the TSource and TTarget to convert between the types.

Delegate

static

Provides an OpcDataTypeMapper which uses the convert and convertBack delegates.

public static OpcDataTypeMapper Delegate<TSource, TTarget>(
    Func<TSource, IFormatProvider, TTarget> convert,
    Func<TTarget, IFormatProvider, TSource> convertBack)

Public Shared Function [Delegate](Of TSource, TTarget)(
    convert As Func(Of TSource, IFormatProvider, TTarget),
    convertBack As Func(Of TTarget, IFormatProvider, TSource)) As OpcDataTypeMapper

Type parameters

Name	Description
TSource	The Type which is to be mapped to the TTarget type.
TTarget	The resulting Type after mapping an object of the TSource type.

Parameters

Name	Type	Description
convert	Func<TSource, IFormatProvider, TTarget>	The delegate to use to map the TSourceobject to the TTarget type.
convertBack	Func<TTarget, IFormatProvider, TSource>	The delegate to use to map the TTargetobject back to the TSource type.

Returns

OpcDataTypeMapper

Exceptions

Exception	Condition
ArgumentNullException	The convert or convertBack is a null reference (Nothing in Visual Basic).
