type-conversion

My Classes are;

class BaseClass
{

}

class DerivedClass1 : BaseClass
{

}

class GenericClass<T>
{

}

class DerivedClass2 : BaseClass
{
    GenericClass<DerivedClass1> subItem;
}

I want to access all fields of DerivedClass2 class. I use System.Reflection and FieldInfo.GetValue() method;

Bu I cant get subItem field. FieldInfo.GetValue() method return type is "object". And I cant cast to GenericClass<DerivedClass1> or I cant get DerivedClass1 type. I try this with BaseClass

BaseClass instance = FieldInfo.Getvalue(this) as GenericClass<BaseClass>;

but instance is null. How to get instance with type or how to get only type?

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

This question might seem trivial and also stupid at the first glance, but it is much more than this. I have an array of any type T (T[]) and I want to convert it into a List generic (List<T>).

I'm hashing a file with one or more hash algorithms. When I tried to parametrize which hash types I want, it got a lot messier than I was hoping. I think I'm missing a chance to make better use of generics or LINQ. I also don't like that I have to use a Type[] as the parameter instead of limiting… >>> More
