Conversion.CTypeDynamic<TargetType> Method (Object)

Syntax

'Declaration
Public Shared Function CTypeDynamic(Of TargetType) ( _
    Expression As Object _
) As TargetType

public static TargetType CTypeDynamic<TargetType>(
    Object Expression
)

Remarks

The CTypeDynamic method converts the object passed as the Expression parameter to the type specified by the type of the generic parameter. If the object is a dynamic object, the CTypeDynamic method applies available dynamic conversions.

The CTypeDynamic method applies dynamic conversions in accordance with the conversion semantics defined by the object itself. If a dynamic object inherits from DynamicObject, the CTypeDynamic method first attempts to perform the conversion by using a user-defined, static conversion. If the user-defined, static conversion fails, the CTypeDynamic method attempts to perform the conversion by using dynamic conversions. If a dynamic object implements IDynamicMetaObjectProvider, the CTypeDynamic method gives precedence to dynamic conversions over user-defined, static conversions.

Examples

The following example uses the CTypeDynamic method to convert a dynamic object to a string by using the conversion defined by the dynamic object.

Imports System.Dynamic

Module Module1
    Sub Main()
        Dim dyn As Object = New SampleDynamicObject
        Dim str = CTypeDynamic(Of String)(dyn)
        Console.WriteLine(str)
    End Sub
End Module

Class SampleDynamicObject
    Inherits DynamicObject

    Public Overrides Function TryConvert(ByVal binder As ConvertBinder,
                                         ByRef result As Object) As Boolean

        If binder.Type = GetType(String) Then
            result = "Sample String"
            Return True
        End If

        Return False
    End Function
End Class
