bytearray

I've got a maybe simple problem, but at the moment I am not able to solve it. I have an Object and I need to convert it into a byte[].

public byte[] GetMapiPropertyBytes(string propIdentifier)
{
    return (byte[])this.GetMapiProperty(propIdentifier); //InvalidCastException 
}

Exception:

Unable to cast COM object of type 'System.__ComObject' to class type 'System.Byte[]'. Instances of types that represent COM components cannot be cast to types that do not represent COM components; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface.

So far so good - I've tried to serialize it, but I got another exception - NOT serializable

Could someone help me? I need a method to convert it...

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
