help you fix your problem By doing a catch (Exception ex) you also catch all exceptions which derive from Exception. If you then want the type of it, you can just call ex.GetType(). Hope it helped ;)

Why does Reflection's SetValue throw an exception?

Hope that helps Your first argument on SetValue is incorrect - it's try to set the property on the PropertyInfo.
You probably meant:
 p.SetValue(this, source.GetValue(v, null), null);

like below fixes the issue I would like to implement a method with the following logic: , You could always try this, which uses generics:
Public Sub ThrowException(Of T As Exception)(message As String)
    Throw DirectCast(Activator.CreateInstance(GetType(T), message), T)
End Sub
ThrowException(Of ArgumentException)("Error Message here")

wish help you to fix your issue If you cast the result of Setup to IThrows, it works. I'm not sure why it fails how you have it; maybe because the runtime type of moq.Setup(func) is not normally visible (it's internal to Moq).
((IThrows)moq.Setup(func)).Throws(new Exception());

it helps some times In field variable in your loop you have the definition of field and when you want to get the value of field you should pass the object to the GetValue method, so in your code you need to write something like this
int[] array = (int[])field.GetValue(testClass);

hope this fix your issue I think I understand what you're trying to do.
It appears that you're trying to set properties like this:
var o2 = new List<MyObject2>();
var mso = new MyStructuredObjects();
SetValuesToObjectsToIntegrate(ref mso, o2);
private void SetValuesToObjectsToIntegrate<T>(MyStructuredObjects returnedObject, T obj)
{
    foreach (var propertyInfo in typeof(MyStructuredObjects).GetProperties())
    {
        if (typeof(T) == propertyInfo.PropertyType)
        {
            propertyInfo.SetValue(returnedObject, obj, null);
        }
    }
}
var o2 = new List<MyObject2>();
var mso = new MyStructuredObjects();
SetValuesToObjectsToIntegrate(mso, o2);
