Default value of any type

For any given type i want to know its default value.

There is a neat keyword called default for doing this like
object x = default(DateTime);
but I have an instance of Type (called someType) and something like
this cant work
object x = default(someType);


Is there any nice way of doing this? I dont really want to write a
huge switch block enumerating all types in .NET !
 
The default keyword returns null for reference types. Use the GetConstructor
method of the Type class, passing it an empty Type array, to get a
ConstructorInfo instance, and then call the Invoke method, passing null to
it:

object x = someType.GetConstructor(System.Type.EmptyTypes).Invoke(null);
