Getting a property using reflection part 2
From Wiki
So the first part was simple.
And I want to keep it simple for just a while.
I want to make the reflection part a bit easier for myself and for others.
So I made a Class with shared methods (one for now).
- Namespace Common
- ''' <summary>
- '''
- ''' </summary>
- ''' <typeparam name="T"></typeparam>
- ''' <typeparam name="K"></typeparam>
- ''' <remarks></remarks>
- Public Class GetPropertyByReflection(Of T, K)
- #Region " Public methods "
- ''' <summary>
- '''
- ''' </summary>
- ''' <param name="PropertyName"></param>
- ''' <param name="ObjectToReflect"></param>
- ''' <returns></returns>
- ''' <remarks></remarks>
- Public Shared Function GetProperty(ByVal PropertyName As String, ByVal ObjectToReflect As K) As T
- Dim _Object As Object = ObjectToReflect
- Return CType(_Object.GetType.GetProperty(PropertyName , Reflection.BindingFlags.Instance Or Reflection.BindingFlags.IgnoreCase Or Reflection.BindingFlags.Public).GetValue(ObjectToReflect, Nothing), T)
- End Function
- #End Region
- #Region " Private methods "
- #End Region
- End Class
- End Namespace
As you can see, I use reflection so the users of this Class don't have to cast and so it is type safe.
This will make the test look a bit like this:
- ''' <summary>
- '''
- ''' </summary>
- ''' <remarks></remarks>
- <Test()> _
- Public Sub TestReflectionGetValueForRemarks()
- Dim _Translated As Common.Interfaces.ITranslated
- _Translated = New Common.Translated
- _Translated.Remarks = "Test"
- Assert.AreEqual("Test", Common.GetPropertyByReflection(Of String, Model.KitManagement.Interfaces.ICondition).GetProperty("Remarks", _Translated))
- End Sub
One line and typesafe, what more do you want? I know the K wasn't really necessary but it makes sure it gets the correct object.
Run it, and green again. Life can be so beautiful.
