Custom type conversion

[MyPantsAreAlive]

Hi all,

How do we convert a source type into a destination type before using reflection to assign value from source field to destination field in below code snippet:

Try
                tempPropertyInfo = tempDestinationObject.GetType.GetProperty(sourceObjectName)
                If Not tempPropertyInfo Is Nothing AndAlso sourceDataTable.Columns.Contains(sourceObjectName) AndAlso tempPropertyInfo.CanWrite Then
                    Select Case tempPropertyInfo.PropertyType.Namespace
                        Case "System"
                            tempPropertyValue = CObj(sourceDataTable.Rows(rowCount).Item(sourceObjectName))
                            If Not tempPropertyValue Is Nothing AndAlso tempPropertyInfo.PropertyType.FullName = "System.DateTime" Then
                                tempPropertyValue = CDate(tempPropertyValue)
                            End If
                        Case Else
                            tempPropertyValue = Activator.CreateInstance(tempPropertyInfo.PropertyType)
                            tempPropertyValue.Value = CObj(sourceDataTable.Rows(rowCount).Item(sourceObjectName))
                    End Select
                    If Not tempPropertyValue Is Nothing Then
                        tempPropertyInfo.SetValue(tempDestinationObject, tempPropertyValue, Nothing)
                    End If
                End If
            Catch ex As Exception
            End Try

When I try to assign a boolean value to a custom data type, I get an unhandled excpetion here

tempPropertyValue.Value = CObj(sourceDataTable.Rows(rowCount).Item(sourceObjectName))

What's the exception message? I notice that you are taking what you suggest might be a boolean, converting it to object, and assigning it to the Value member. You shouldn't need the CObj call, as Item will return an Object anyways, but is Value of type Object? If Value is of type boolean, then CBool would be the correct conversion. However, if Item(sourceObjectName) is not a Boolean, or is Null, that would cause problems, as well.
